mysql template for spring boot
// Step 1: Add the MySQL dependency in the 'pom.xml' file.
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.23</version> <!-- Use the latest version -->
</dependency>
// Step 2: Configure the database properties in 'application.properties' or 'application.yml'.
spring.datasource.url=jdbc:mysql://localhost:3306/your_database_name
spring.datasource.username=your_username
spring.datasource.password=your_password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update
// Step 3: Create a JPA Entity representing your database table.
@Entity
@Table(name = "your_table_name")
public class YourEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
// Add other fields and annotations as needed
}
// Step 4: Create a JpaRepository interface for your entity.
public interface YourEntityRepository extends JpaRepository<YourEntity, Long> {
// Add custom queries if necessary
}
// Step 5: Use the repository in your service or controller.
@Autowired
private YourEntityRepository yourEntityRepository;
// Step 6: Perform database operations using the repository.
YourEntity entity = new YourEntity();
// Set entity fields
yourEntityRepository.save(entity);
List<YourEntity> entities = yourEntityRepository.findAll();
YourEntity retrievedEntity = yourEntityRepository.findById(1L).orElse(null);
yourEntityRepository.deleteById(1L);
Make sure to replace placeholders like "your_database_name," "your_username," "your_password," "your_table_name," and adapt the entity and repository according to your specific use case.
