I am working on a Spring project. I have faced a problem; i cannot connect to mysql driver. Here is pom.xml :

<dependencies>
  <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
 <dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
  </dependency>
</dependencies>
And here is  application.properties code: 
 spring.datasource.url=jdbc:mysql://localhost:3306/stock_produit
 spring.datasource.username=root
 spring.datasource.password=
 spring.jpa.hibernate.ddl-auto=create
 spring.datasource.driver-class-name=com.mysql.cj.jdbc

Any help is appreciated. 
                which database you trying to connect with your application. Please put the drivers accordingly..

In application.properties driver class name that you defined is not found in spring data dependency. So,
I think you should try this..
spring.datasource.url=jdbc:mysql://localhost:3306/stock_produit
spring.datasource.driverClassName=com.mysql.jdbc.Driver
instead of 
spring.datasource.url=jdbc:mysql://localhost:3306/stock_produit
spring.datasource.driver-class-name=com.mysql.cj.jdbc 
  
Note: You trying to connect with mysql database, which requires com.mysql.jdbc.Driver and it is available in spring-boot-data dependency. 
Hope this help you out..
