hibernate关于视图的处理

hibernate处理视图和处理表情况是一样的，以下是通过springboot和jpa进行的测试
实体：

@Entity
public class Person {
	@Id
	@GeneratedValue
	private Long id;
	private String name;
	private Integer age;
	private String address;
	/*get和set方法*/
}
@Entity
public class Student {
	@Id
	@GeneratedValue
	private Long id;
	private String name;
	/*get和set方法*/
}
@Entity//此类为视图类
public class Vps {
	@Id//此处必须加id，id可以加到任意字段
	private Long pid;
	private Long sid;
	private String sname;
	private Integer age;
	/*get和set方法*/
}

注意：视图实体也是必须有id的，id可以加到任意字段，本人在pid，sid，sname，age四个字段上都实验成功
视图建立的sql语句：

select `person`.`id` AS `pid`,`student`.`id` AS `sid`,`student`.`name` AS `sname`,`person`.`age` AS `age` from (`person` join `student`)

dao层：

public interface VpsRepository extends JpaRepository<Vps, Long> {
}

service层：

@Service
public class DemoServiceImpl implements DemoService {
	@Autowired
	private VpsRepository vpsRepository;

	@Transactional(readOnly = true)
	@Override
	public List<Vps> findAll() {
		return vpsRepository.findAll();
	}
}

控制层：

@RestController
public class MyController {
	@RequestMapping("/vpslist")
	public List<Vps> vpslist() {
		return demoService.findAll();
	}
}

结果：

[ {
  "pid" : 1,
  "sid" : 1,
  "sname" : "s1",
  "age" : 1
} ]
