Ошибка no suitable driver found for jdbc mysql

The error «java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test» occurs when you try to connect MySQL database running on your localhost, listening on port 3306 port from Java program but either you don’t have MySQL JDBC driver in your classpath or driver is not registered before calling the getConnection() method. Since JDBC API is part of JDK itself, when you write a Java program to connect any database like MySQL, SQL Server, or Oracle, everything compiles fine, as you only use classes from JDK but at runtime, when the JDBC driver which is required to connect to the database is not available, JDBC API either throws this error or «java.lang.ClassNotFoundException: com.mysql.jdbc.Driver».

The most common reason for this error is missing MySQL JDBC Driver JAR e.g. mysql-connector-java-5.0.8.jar not available in the classpath. Another common reason is you are not registering the driver before calling the getConnection() and you are running on Java version lower than 6 and not using a JDBC 4.0 compliant driver. We’ll see these reasons in more detail in this article.

JAR not available in Classpath

If mysql-connector-java-5.0.8.jar is not available in classpath then you cannot connect to MySQL database from Java. Your program like below will compile fine but as soon as you will run it you will get the error «java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test» because of the JDBC URL format «jdbc:mysql» is not matching with any registered JDBC driver.

Here is our Java program to demonstrate this error. This program reproduces this error by first leaving out the required JDBC JAR from the classpath and also not explicitly registering the driver before use by not calling the Class.forName() method.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;

/*
 * Java Program to to connect to MySQL database and
 * fix java.sql.SQLException: No suitable driver found 
 * for jdbc:mysql://localhost:3306
 * error which occur if JAR is missing or you fail to register driver.
 */

public class Main {

  public static void main(String[] args) {

    Connection dbConnection = null;

    try {
      String url = "jdbc:mysql://localhost:3306/test";
      Properties info = new Properties();
      info.put("user", "root");
      info.put("password", "test");

      dbConnection = DriverManager.getConnection(url, info);

      if (dbConnection != null) {
        System.out.println("Successfully connected to MySQL database test");
      }

    } catch (SQLException ex) {
      System.out.println("An error occurred while connecting MySQL databse");
      ex.printStackTrace();
    }

  }

}

Output
An error occurred while connecting MySQL databse
java.sql.SQLException: No suitable driver found 
for jdbc:mysql://localhost:3306/test

You need to do two things in order to solve this problem:

1) Add mysql-connector-java-5.0.8.jar or any other MySQL JAR corresponding to the MySQL database you are connecting. If you don’t have MySQL JDBC driver, you can download from here http://dev.mysql.com/downloads/connector/j/3.1.html

2) Add following line of code just before the call to Connection.getConnection(url, props) method

// load and register JDBC driver for MySQL
Class.forName("com.mysql.jdbc.Driver"); 

This will load the class, the JDBC driver to connect MySQL, com.mysql.jdbc.Driver from mysql-connector-java-5.0.8.jar and register it with JDBC API. Once you do that «java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test» will go away.

Also, it’s worth noting that JDBC 4.0 released with Java SE 6 has now introduced auto-loading of JDBC driver class, which means you don’t need Class.forName(«com.mysql.jdbc.Driver»); any more, but only when you are running on at least Java 6 and your driver JAR is also JDBC 4.0 compliant

For example, the driver used in this program «mysql-connector-java-5.0.8.jar» is not JDBC 4.0 compliant, so even if you run this program in Java 6, 7 or Java 8, it will not work, but if you use mysql-connector-java-5.1.36.jar then even without adding «Class.forName(«com.mysql.jdbc.Driver»);», your program will work fine. Why? because JDBC will automatically load and register the driver, provided you have mysql-connector-java-5.1.36.jar file in your classpath. .

That’s all about how to solve «java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test» error in Java program. This error occurs if JDBC is not able to find a suitable driver for the URL format passed to the getConnection() method e.g. «jdbc:mysql://» in our case. 

Друзья, помогите разобраться уже пару дней пытаюсь решить проблему, изучаю работу с БД, создал проект в Idea и БД на MySQL, вроде все подключик как положено, mysql connector импортировал в проект, но при запуске проекта выдает ошибку No suitable driver found for jdbc:mysql:localhost:3306/Park, в чем проблема не пойму mysql connector ставил разных версий и просто так и через maven результат один, в чем может быть проблема.
Если протестить соединение с БД из вкладки Database то проверка проходит, а когда запускаешь проект выдает ошибку

The java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/testdb exception occurs if the suitable driver is not found to connect mysql database from java application. The MySQL JDBC driver is not loaded in java either because the driver jar is not available in the class path, or because it is not possible to load the mysql driver jar. If no suitable driver is found in the java class path, the exception java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/testdb will be thrown.

The MySQL JDBC driver is used to connect your Java application to a MySQL database. The mysql driver sends the database query from java to the database. The Mysql database executes the query and returns the results. The MySQL JDBC driver receives the data from the MySQL database and sends it back to the Java application.

If the MySQL JDBC driver is not loaded, the Java program will throw the exception java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/testdb.

Exception

The stack trace of the exception will be shown as shown below. The exception java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/testdb  is due to the driver class not loaded in java.

Exception in thread "main" java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/testdb
	at java.sql.DriverManager.getConnection(DriverManager.java:689)
	at java.sql.DriverManager.getConnection(DriverManager.java:247)
	at com.yawintutor.DBConnection.main(DBConnection.java:13)

How to reproduce this exception

If the Java application can not load the MySQL JDBC driver class or the MySQL JDBC class is not available in the Java class path, the exception java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/testdb will be thrown. This exception will be reproduced in the example below.

package com.yawintutor;

import java.sql.Connection;
import java.sql.DriverManager;

public class DBConnection {
	public static void main(String[] args) throws Exception {
		String url = "jdbc:mysql://localhost:3306/testdb";
		String username = "root";
		String password = "root";

		Connection con = DriverManager.getConnection(url, username, password);
		if (con != null) {
			System.out.println("Database Connected successfully");
		} else {
			System.out.println("Database Connection failed");
		}
	}
}

Solution 1

If the MySQL JDBC driver jar is available in the class path and the driver class is unable to load, the driver class must be loaded in the java using class.forName() method. The forName() method will load the class from the fully qualified class name specified as an argument. The example below demonstrates how to load the MySQL JDBC driver class using the class.forName() method.

package com.yawintutor;

import java.sql.Connection;
import java.sql.DriverManager;

public class DBConnection {
	public static void main(String[] args) throws Exception {
		Class.forName("com.mysql.cj.jdbc.Driver");
		String url = "jdbc:mysql://localhost:3306/testdb";
		String username = "root";
		String password = "root";

		Connection con = DriverManager.getConnection(url, username, password);
		if (con != null) {
			System.out.println("Database Connected successfully");
		} else {
			System.out.println("Database Connection failed");
		}
	}
}

Solution 2

If you are using mysql database version till 5.x.x, the MySQL JDBC driver “com.mysql.cj.jdbc.Driver” will not be available. For the older mysql databases the driver class “com.mysql.jdbc.Driver” must be used. The java program will be as like below.

package com.yawintutor;

import java.sql.Connection;
import java.sql.DriverManager;

public class DBConnection {
	public static void main(String[] args) throws Exception {
		Class.forName("com.mysql.jdbc.Driver");
		String url = "jdbc:mysql://localhost:3306/testdb";
		String username = "root";
		String password = "root@123";

		Connection con = DriverManager.getConnection(url, username, password);
		if (con != null) {
			System.out.println("Database Connected successfully");
		} else {
			System.out.println("Database Connection failed");
		}
	}
}

Solution 3

If the MySQL JDBC driver jar is not available in the java class path, download the mysql driver jar from https://dev.mysql.com/downloads/connector/j/. The name of mysql driver jar is same as mysql-connector-java-8.0.20.jar. Add the jar to the java class path.

download the jar mysql-connector-java-8.0.20.jar from https://dev.mysql.com/downloads/connector/j/ 
( 
  goto https://dev.mysql.com/downloads/connector/j/
  select "Select Operating System:" as your operating system and install
      or
  select "Select Operating System:" as "Platform Independent", download the zip and extract
)

Add in your java project.

In eclipse
Right click in mysql-connector-java-8.0.20.jar -> Build Path -> Add to Build Path

Solution 4

If the java project is a maven project, add the mysql connector dependency in the pom.xml. The dependency will download the mysql-connector-java-8.0.22.jar in the repository and link to the project. The latest mysql connector dependency can be found in https://mvnrepository.com/artifact/mysql/mysql-connector-java

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.22</version>
</dependency>

Solution 5

If the java project is build using the Gradle, add the dependency as below. When the project is build, the MySQL JDBC driver will be added to the java project.

dependencies {
    compile 'mysql:mysql-connector-java:8.0.22'
}

No suitable driver found for JDBC is an exception in Java that generally occurs when any driver is not found for making the database connectivity. In this section, we will discuss why we get such an error and what should be done to get rid of this exception so that it may not occur the next time.

Before discussing the exception, we should take a brief knowledge that what is a JDBC Driver.

What is a JDBC Driver

The JDBC (Java Database Connectivity) Driver is a driver that makes connectivity between a database and Java software. The JDBC driver can be understood as a driver that lets the database and Java application interact with each other. In JDBC, there are four different types of drivers that are to be used as per the requirement of the application. These JDBC divers are:

1. JDBC-ODBC bridge driver
2. Thin Layer driver
3. Native API driver
4. Network Protocol Driver

All four drivers have their own usage as well as pros and cons. To know more about JDBC Drivers, do visit: https://www.javatpoint.com/jdbc-driver section of our Java tutorial.

What is the Error and Why it Occurs?

Generally, «no suitable driver found» refers to throwing an error, i.e., «java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test» in the console. The error occurs when we are trying to connect to the MySql (or any other) database that is existing on your local machine, i.e., localhost, and listens to the specified port number which is set for the mysql and it founds that either no JDBC driver was registered before invoking the DriverManager.getConnection () method or we might not have added the MySQL JDBC driver to the classpath in the IDE. In case we are running a simple Java code with no requirement of database connectivity, the Java API executes it correctly and well, but if there is the need for a JDBC driver, an error is thrown, which is the «class not found» error. In simple words, such an error is thrown when no suitable driver is found by the Java API so that it could connect the Java application to the database.

How to remove the error

Now the question is how to get rid of such error. In order to resolve the problem or error, one needs to add the MYSQL Connector JAR to the classpath because the classpath includes the JDBC Driver for the MYSQL through which the connection is generated between the Java code and the database. In order to add the MYSQL connector JAR file to the IDE or tool we are using, we need to go through some quite simple steps. These steps are as follows:

For Eclipse and NetBeans IDE

1) Open any internet browser on the system and search for MySQL Connector download in the search tab. Several downloading links will appear. Click on the MYSQL website https://www.mysql.com/products/connector/ from it and download the latest version of the MYSQL connector by selecting your system specs.

2) After the successful download of the MYSQL Connector, it will be seen at the default Downloads folder of your system, as you can see in the below snippet:

3) Now, open the IDE you are working upon, either NetBeans or Eclipse, and also any other tool/IDE, whichever you use. Here, we have used Eclipse IDE.

4) Go to your project and right-click on it. A list of options will appear. Select and click on Build Path > Configure Build Path, and the Java Build Path dialog box will open up, as you can see in the below snippet:

5) Click on Add External JARs and move to the location where you have downloaded the Mysql Connector, as you can see in the below snippet:

6) Select the Mysql Connector and click on Open. The JAR file will get added to your project build path, as you can see in the below snippet:

7) Click on Apply and Close, and the JDBC Driver will be added to your Eclipse IDE.

Run the JDBC connection code once again, and this time you will not get the «No suitable driver found for JDBC» exception instead of other errors if you made any other syntax problem.

9) The JDBC Driver will get connected successfully, and the connection will get established successfully.

Point to be noted:

• If you are using Java SE 6 with JDBC 4.0, then you may not require to load and register the driver because the new Java feature provides autoloading of the JDBC driver class. Due to which there is no requirement of using Class.forName(«com.mysql.jdbc.Driver»); statement. However, if the JDBC Jar you are using is old, i.e., JDBC 4.0 compliant with Java SE 6, then you may need to create this statement.
• In brief, we can say that such an error occurs when no JDBC JAR file is added to the classpath of Java. Just we need to add the JAR file to the classpath and then execute the code. The code will hopefully get executed with success.
