How to Connect a Java Spring Boot Application to a MySQL Database

Connecting a Spring Boot application to a MySQL database is straightforward with the right dependencies and configurations. Here's a step-by-step guide:

1. Add Dependencies

In your pom.xml (for Maven projects), include:

xml

<dependency>

    <groupId>mysql</groupId>

    <artifactId>mysql-connector-java</artifactId>

</dependency>

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-data-jpa</artifactId>

</dependency>

2. Configure application.properties

In src/main/resources/application.properties, add:

properties

spring.datasource.url=jdbc:mysql://localhost:3306/your_database_name

spring.datasource.username=your_username

spring.datasource.password=your_password

spring.jpa.hibernate.ddl-auto=update

spring.jpa.show-sql=true

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect

3. Create an Entity Class

java

@Entity

public class User {

   @Id

   @GeneratedValue(strategy = GenerationType.IDENTITY)

   private Long id;

   private String name;

   private String email;

}

4. Create a Repository

java

public interface UserRepository extends JpaRepository<User, Long> {

}

5. Use in a Service or Controller

Now you can use UserRepository to interact with your MySQL database.
