Uri is not absolute ошибка

I’m trying to connect to a Spring RESTful service on the same server where my webapp is running.

I’d like to use a «relative» path because it could be installed on several environments (localhost, test, production) but I get the error message: URI is not absolute.

How can I call a service running on another webapp on the same server?

My code is like following:

final RestTemplate restTemplate = new RestTemplate();
URI uri;
try {
    String url = "app2/myservice?par=1";
    uri = new URI(url);
    String result = restTemplate.getForObject(uri, String.class);
    System.out.println(result);
} catch (URISyntaxException e) {
    logger.error(e.getMessage());
}

Thanks.

Update:

I solved it by getting the host, port, etc… from the request, could it be a right and elegant solution? This’s my actual simplified code:

String scheme = request.getScheme();
String userInfo = request.getRemoteUser();
String host = request.getLocalAddr();
int port = request.getLocalPort();
String path = "/app2/myservice";
String query = "par=1";
URI uri = new URI(scheme, userInfo, host, port, path, query, null);
boolean isOK = restTemplate.getForObject(uri, Boolean.class);
if (isOK) {
    System.out.println("Is OK");
}

java.lang. IllegalArgumentException: URI is not absolute occurs when a relative url is used to identify the resource. In the spring boot RestTemplate, the complete url will be used to invoke the rest call. If the relative url is used in the restful call, the java exception java.lang. IllegalArgumentException: URI is not absolute would be thrown.

A resource can be invoked in java using a complete url. If the relative url is used, the relative url can not be converted to an absolute url. Therefore, the resource can’t be identified. The exception URI is not absolute will be thrown.

Exception

The exception java.lang. IllegalArgumentException: URI is not absolute stack trace will be shown as below in the spring boot. The root cause will be thrown from the java.

How to recreate this exception

If a relative url is sent to a rest call in the RestTemplate, a relative url can not be converted to an absolute url. This is why the exception “java.lang.IllegalArgumentException: URI is not absolute” would be thrown. In the “/getstudent” rest call invokes another rest call using the relative url “/student”.

package com.yawintutor;

import javax.servlet.http.HttpServletRequest;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
public class TestController {

	@GetMapping(value = "/student")
	public Student getStudent() {
		return new Student(1, "name1");
	}

	@GetMapping(value = "/getstudent")
	private Student getStudentObject(HttpServletRequest request)
	{
	    String uri = "/student";
	    RestTemplate restTemplate = new RestTemplate();
	    Student result = restTemplate.getForObject(uri, Student.class);
	    return result; 
	}
}

Solution 1

If a relative url is sent to a rest call in the RestTemplate, the relative url has to be changed to an absolute url. The RestTemplate will use the absolute url to identify the resource. In the example below, the complete url “http:/localhost:8080/student” is used to invoke a rest call using RestTemplate.

package com.yawintutor;

import javax.servlet.http.HttpServletRequest;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
public class TestController {

	@GetMapping(value = "/student")
	public Student getStudent() {
		return new Student(1, "name1");
	}

	@GetMapping(value = "/getstudent")
	private Student getStudentObject(HttpServletRequest request)
	{
	    String uri = "http://localhost:8080/student";
	    RestTemplate restTemplate = new RestTemplate();
	    Student result = restTemplate.getForObject(uri, Student.class);
	    return result; 
	}
}

Solution 2

If you are using a relative url in a rest call that refers to the same tomcat server, use the HTTPRequest object to construct a complete url before submitting it to the rest template. The example below demonstrates how to create a complete url from the relative url to the same server.

package com.yawintutor;

import javax.servlet.http.HttpServletRequest;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
public class TestController {

	@GetMapping(value = "/student")
	public Student getStudent() {
		return new Student(1, "name1");
	}

	@GetMapping(value = "/getstudent")
	private Student getStudentObject(HttpServletRequest request)
	{
	    String requestURL = request.getRequestURL().substring(0, request.getRequestURL().indexOf(request.getRequestURI()));
	    String uri = requestURL + "/student";
	    RestTemplate restTemplate = new RestTemplate();
	    Student result = restTemplate.getForObject(uri, Student.class);
	    return result; 
	}
}

Solution 3

If the relative url is used in RestTemplete that must be referred to an external host server, the external host server url can be externalized in the application.properties files. The properties can be added to the relative url as shown in the example below.

application.properties

external.server.url=http://www.yawintutor.com

TestController.java

package com.yawintutor;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
public class TestController {

	@Value("${external.server.url}")
	String externalServerURL;
	
	@GetMapping(value = "/student")
	public Student getStudent() {
		return new Student(1, "name1");
	}

	@GetMapping(value = "/getstudent")
	private Student getStudentObject()
	{
	    String uri = externalServerURL + "/student";
	    RestTemplate restTemplate = new RestTemplate();
	    Student result = restTemplate.getForObject(uri, Student.class);
	    return result; 
	}
}

* Trim extraneous whitespace from base64-encoded aia The base64 utility on macOS writes a carriage return at the end of the base64 encoded string. When App Inventor attempts to read a project template with this extra whitespace, it causes an exception to be thrown since the server's decode() implementation expects a string with a length multiple of 4. This change switches to using decodeLines(), which ignores whitespace.

This generally isn't a problem, but it affects the warning indicator toggle button. Blockly starts a drag at the mousedown but then we never will see a mouseup or click event. This change registers a mouse down listener on the toggle to stop propagation to Blockly so that the warning indicator can receive the click event. We also update to include support for touch events on the toggle button to support App Inventor on tablets.

If we don’t App Engine sends RST packets which causes issues for some buildserver infrastructures. Also limit project size to 10MB up-front (rather then after an IOException is thrown). Add reporting to the buildserver status page to report the number of Java threads.

LineString processing was also broken, resulting in a coordinate string without values. Setting the Source to None... would remove the components but not clear the features off the map. This commit addresses three changes: 1. Refactors how naming of map features is handled during the loading of GeoJSON into a MockFeatureCollection so that each component has a unique name. 2. It corrects handling of LineString coordinates when the line string is not part of a MultiLineString construct. 3. It cleans up how features are removed when a feature collection is cleared.

This fix sets the minimum size of a button to 0x0 so that it can take on the image size regardless of what the platform's default dimensions for a button.

This was to optimize the interaction between the load/upgrade process and workspace resizes. However, in rare instances it seems to result in blocks not being placed correctly. This change removes the special handling of upgrading. Instead, it disables and enables the Blockly event system during a load/upgrade operation. At the end of the upgrade process (if needed), it will also force a save of the blocks workspace.

This change enables logging only if the user is an Admin, since only Admins have access to the debugger panel to begin with. This reduces the number of cycles spent on logging for the vast majority of App Inventor users. We also optimize how the log is constructed so that users with Admin rights have reasonable performance on complicated projects.

While using WebRTC assets (images, sounds, etc.) are downloaded directly to the Companion from the MIT App Inventor server without being redirected through the user’s browser. By supporting WebRTC we pave the way for offering MIT App Inventor over https. The current HTTP based communications system used today (without WebRTC) prohibits us from using https for MIT App Inventor itself. This version of code supports both the new WebRTC approach as well as the pre-WebRTC approach both within the MIT App Inventor client (browser) and the Companion. The new Companion will use WebRTC by default, but can be told to use the HTTP based system (called a “Legacy Connection”) by checking a box on the Companion home screen. We will have to remove HTTP (Legacy) support prior to serving MIT App Inventor over https.

So instead, we break the large YAIL forms into smaller YAIL forms that can each be evaled on the device correctly.

However, many people intuitively expect that they can construct a list of components as part of the global declaration. This changes allows for component blocks and property getters to be used in a blocks tree with a global declaration root node. Change-Id: I69d26716ebf4bfcdd52465f15eaf75af1c4170cf * Update LocationSensor documentation Change-Id: I00d6063b297aa17da1e30cd140cf0403b0d3642c * Fix build system dependency relationships (mit-cml#1605) PR mit-cml#1569 moved some constants into the shared ComponentConstants.jar file. Building the full system works with this change, but only due to implicit relationships in the order of how targets are executed. Unfortunately, these implicit relationships are not present when running either `ant extensions` or `ant RunLocalBuildServer`, which results in a broken build. This changes does two things: 1. Add an explicit dependency to CopyToRunLibDir in buildserver on the target to build ComponentConstants.jar 2. Breaks a cyclic dependency of the components module on the buildserver module on the components module due to the extensions mechanism wanting to build the buildserver to aggregate the dependencies of the AndroidRuntime into a single directory. This is accomplished by breaking the move into two parts, one which moves the files into the public build directory, which is now populated by the components build.xml, and the second which copies them into the buildserver in its build.xml. This allows the extensions mechanism to use the public directory so it no longer needs to reference the buildserver.

However, there is a logic bug due to the fact that the empty string is falsey in JavaScript. This fix also checks specifically for the empty string as well so that the default value will be sent. * Simplify AndroidRuntime classpath further (mit-cml#1617) PR mit-cml#1605 made components manage parts of the classpath instead of the buildserver. This move means that all of AndroidRuntime's dependencies are managed within components/build.xml, and so we can further simplify the classpath for all of the targets within the components module. This change introduces an AndroidRuntime.path reference that is constructed from the dependencies set created by the aforementioned PR. It becomes a single point to introduce dependencies targetting the Android platform, including extension writing, and is used both for compilation and unit test evaluation. * Make FormPropertiesAnalyzer handle Windows line endings (mit-cml#1556) Change-Id: Id58ad71b23a4132db983e8a2c9d8dce6919c4433 * WidthPercent, HeightPercent, Width & Height Tooltips, Documentation (mit-cml#1595) * Use built-in (rejection algorithm) random sampling The original method, uniform integer modulo 100000, is biased in distribution.

Once this process starts, enough things are in motion that it is best to quit the Companion and start a fresh copy if a different code is needed. If the same code is entered more then once, we just ignore the second attempt. This often happens when someone scans a QR Code and then presses the "Connect" Button because they do not know that they don't have to do that. Effectively we are "de-bouncing" Change-Id: I06b20c5d9cdb07999a380d9f877edd111e0357c5 * Rename image joinwithseparator.png Changed the extension from PNG to png (because case matters!)

Functionally, it behaves the same as a checkbox: the ON state is equivalent to checked. Since iOS does not have a checkbox and only offers toggle switches, this component paves the way for an on/off component that is shared by both Android and iOS. The toggle switch is a 2-color control, which means that there are 4 configurable colors, 2 for on and 2 for off. * Simplify the WebRTC Poller Eliminate the single threaded executor because it is not needed. Instead use Timer.scheduleAtFixedRate() to trigger the Poller once per second. This approach is more correct and simpler. Also, ignore an empty response from the Rendezvous server (which means that it hasn’t received any ICE Candidates from the browser yet). Previously we attempted to JSON parse it and threw an exception (which was logged and ignored).

This will help us keep track of how many Companions are out there and what version of Android (and the Companion) they are running on. Note: The id is generated by the ACRA Library and is persistent across upgrades of the Companion. However it will be re-created if the Companion is uninstalled and then re-installed. It is not related in any way to any Android provided identifier, which minimizes the privacy impact of this identifier.

This is bad from a UX perspective as the user then has to change the language and wait for the site to reload. It also interrupts whatever workflow they were currently doing (e.g., when opening a template project). This change stores the last locale from the query string as the user's preferred locale. When a locale isn't specified in the URL, we will check the locale and if it is set, redirect to that page automatically. To also save on performing actions that would be canceled by the redirect, we also reorder some initialization of Ode so that it only occurs if the redirect won't happen.

However, when we load the list of projects initially, this will get called `O(n)` times, resulting in `O(n^2 log n)` performance. For many users, the number of projects might be small and this load time may appear negligible. However, for more prolific users with hunders of projects, this may result in multiple seconds wait time while the list is first loaded. This fix defers sorting the list until all projects have been added.

However, the documentation for the properties, methods, and events of an App Inventor component shared in this way must typically be written generic enough so that they make sense when shown on concrete classes. This can lead to either awkward/generic sounding documentation or requires that the component author override all of the relevant features on the component to provide component-specific descriptions. This change makes it so that descriptions of components, properties, methods, and events can contain one or more %type% tokens that can be substituted with the name of the concrete representation shown to the App Inventor user. This allows for documentation to be shared at the super class level while still making it sound specific to the individual component type. Change-Id: Ida4eb22bec12b2e33ac73de2bb5706d1683b227a * Update Sort By Category Function Change-Id: If1fe3358fb87be47a90dd90a79c794a751ab7288 * Register YaFormEditor and YaBlocksEditor earlier Prior to this change, YaFormEditor and YaBlocksEditor are registered in loadDesigner, which is called from onShow. This is problematic because if the screen hasn't been opened in the current session and the user deletes an extension, the unopened screens are not notified of the change. When the project is reloaded, it will fail to load because the unopened screens still referenced the deleted extension. This change moves the registration of YaFormEditor and YaBlocksEditor as FormChangeListeners to the onFileLoaded method so that they are made aware of project-level changes (like removing an extension) even if they are never viewed in a session.

Issue

My Controller calls the service to post information about a car like below and it works fine. However, my unit test fails with the IllegalArgumentException: URI is not absolute exception and none of the posts on SO were able to help with it.

Here is my controller

@RestController
@RequestMapping("/cars")  
public class CarController {
@Autowired
CarService carService;
@PostMapping(consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<CarResponse> getCar(@RequestBody CarRequest carRequest, @RequestHeader HttpHeaders httpHeaders) {
ResponseEntity<CarResponse> carResponse = carService.getCard(carRequest, httpHeaders);
return carResponse;
}
}

Here is my service class:

@Service
public class MyServiceImpl implements MyService {
@Value("${myUri}")
private String uri;
public void setUri(String uri) { this.uri = uri; }
@Override
public ResponseEntity<CarResponse> postCar(CarRequest carRequest, HttpHeaders httpHeaders) {
List<String> authHeader = httpHeaders.get("authorization");
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", authHeader.get(0));
HttpEntity<CarRequest> request = new HttpEntity<CarRequest>(carRequest, headers);
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<CarResponse> carResponse = restTemplate.postForEntity(uri, request, CarResponse.class);
return cardResponse;
}
}

However, I am having trouble getting my unit test to work. The below tests throws IllegalArgumentException: URI is not absolute exception:

public class CarServiceTest {
@InjectMocks
CarServiceImpl carServiceSut;
@Mock
RestTemplate restTemplateMock;
CardResponse cardResponseFake = new CardResponse();
@BeforeEach
void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
cardResponseFake.setCarVin(12345);
}
@Test
final void test_GetCars() {
// Arrange
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", anyString());
ResponseEntity<CarResponse> carResponseEntity = new ResponseEntity(carResponseFake, HttpStatus.OK);
String uri = "http://FAKE/URI/myapi/cars";
carServiceSut.setUri(uri);
when(restTemplateMock.postForEntity(
eq(uri), 
Mockito.<HttpEntity<CarRequest>> any(), 
Mockito.<Class<CarResponse>> any()))
.thenReturn(carResponseEntity);
// Act
**// NOTE: Calling this requires real uri, real authentication,
// real database which is contradicting with mocking and makes
// this an integration test rather than unit test.**
ResponseEntity<CarResponse> carResponseMock = carServiceSut.getCar(carRequestFake, headers); 
// Assert
assertEquals(carResponseEntity.getBody().getCarVin(), 12345);
}
}

UPDATE 1

I figured out why the «Uri is not absolute» exection is thrown. It is because in my carService above, I use @Value to inject uri from application.properties file, but in unit tests, that is not injected.

So, I added public property to be able to set it and updated the code above, but then I found that the uri has to be a real uri to a real backend, requiring a real database.

In other words, if the uri I pass is a fake uri, the call to carServiceSut.getCar above, will fail which means this turns the test into an integration test.

This contradicts with using mocking in unit tests.
I dont want to call real backend, the restTemplateMock should be mocked and injected into carServiceSut since they are annotated as @Mock and @InjectMock respectively. Therefore, it whould stay a unit test and be isolated without need to call real backend. I have a feeling that Mockito and RestTemplate dont work well together.

Solution

You need to construct your system under test properly.
Currently, MyServiceImpl.uri is null.
More importantly, your mock of RestTemplate is not injected anywhere, and you construct a new RestTemplate in method under test.

As Mockito has no support for partial injection, you need to construct the instance manually in test.

I would:

Use constructor injection to inject both restTemplate and uri:

@Service
public class MyServiceImpl implements MyService {
private RestTemplate restTemplate;
private String uri;
public MyServiceImpl(RestTemplate restTemplate, @Value("${myUri}") uri) {
this.restTemplate = restTemplate;
this.uri = uri;
}

Construct the instance manually:

• drop @Mock and @InjectMocks
• drop Mockito.initMocks call
• use Mockito.mock and constructor in test

public class CarServiceTest {
public static String TEST_URI = "YOUR_URI";
RestTemplate restTemplateMock = Mockito.mock(RestTemplate.class);
CarServiceImpl carServiceSut = new CarServiceImpl(restTemplateMock, TEST_URI):
}

Remove creation of restTemplate in method under test.

If needed, add a config class providing RestTemplate bean (for the application, the test does not need that):

@Configuration
public class AppConfig {
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
}

Note that RestTemplate is thread-safe, one instance per app is enough: Is RestTemplate thread safe?
