Setup Spring Boot with JPA and MySQL

Welcome back to my dev notes!

Few things that I’ve to remember next time I need to setup a Spring Boot project with JPA and MySQL:

Add the following dependencies to your pom.xml:

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
</dependency>

Add the following properties to your application.properties:

spring.datasource.url=jdbc:mysql://localhost:3306/db_name
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

Create your model using @Entity and @Id annotations:

@Entity
public class User {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 private Long id;
 private String name;
 private String email;
 private String password;
 // getters and setters
}

Create your repository extending JpaRepository adding @Repository annotation:

@Repository
public interface UserRepository extends JpaRepository<User, Long> {}

Now you are ready to @Autowired your repository and use it in your services/controllers.

That’s all for today, see you next time!
