SpringBoot整合JPA

IDEA 2019.2

jdk 8

Oracle

一、项目结构

 二、依赖POM

 三、创建项目代码

 启动类 App.java

 entity-->Person.java

@Entity
@Table(name = "person_tab")
@SequenceGenerator(name = "ps",sequenceName = "person_seq",allocationSize = 1)//oracle
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Person {
    @Id
    @GeneratedValue(generator = "ps",strategy = GenerationType.SEQUENCE)
    @Column(name = "p_id")
    private Integer id;
    @Column(name = "p_name")
    private  String name;
    @Column(name = "p_gender")
    private String gender;
}

dao-->IPersonDao.java

@Repository
public interface IPersonDao extends CrudRepository<Person,Integer> {
}

service-IPersonService

public interface IPersonService {
    void add(Person person);
    void  delete(Integer id);
    void update(Person person);
    List<Person> findAll();
}

service-->impl--IPersonServiceImpl

@Service("ips")
@Transactional
public class IPersonServiceImpl implements IPersonService {
    @Autowired
    private IPersonDao dao;
    
    @Override
    public void add(Person person) {
        dao.save(person);
    }

    @Override
    public void delete(Integer id) {
        dao.deleteById(id);
    }

    @Override
    public void update(Person person) {
        dao.save(person);
    }

    @Override
    public List<Person> findAll() {
        return (List<Person>) dao.findAll();
    }
}

contoller 此省略

四、配置文件

 application.yml

 application-dev.yml

 五、测试

@SpringBootTest
@RunWith(SpringJUnit4ClassRunner.class)
public class IPersonServiceImplTest {

    @Resource
    private IPersonService ips;

    @Test
    public void add() {
        Person p=new Person(null, "dxj", "女");
        ips.add(p);
    }

    @Test
    public void delete() {
    }

    @Test
    public void update() {
    }

    @Test
    public void findAll() {
    }
}
