datajpa只能取得左联接表的数据，右表数据拿不到

Question

先看看实体如下 @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; private String sname; private String age; private Integer tid; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; private String tname; 表1的tid等于表2的id，然后在jpa里面写原生sql public interface StudentRepository extends JpaRepository<Student, Integer> { @Query(value = "select s.id,s.sname,s.age,tid,t.id as ttid,t.tname from student s left join teacher t on s.tid=t.id",nativeQuery = true) public List<Student> allStu(); } 再然后调用 List<Student> students = studentRepository.allStu(); return students; 取出的数据 [{ "id": 1, "sname": "小米", "age": "11", "tid": 1 }, { "id": 2, "sname": "小张", "age": "12", "tid": 2 }, { "id": 3, "sname": "小马", "age": "15", "tid": 1 }, { "id": 4, "sname": "小刘", "age": "12", "tid": 1 }]数据如上，然后consloe出来的sql如下Hibernate: select s.id,s.sname,s.age,tid,t.id as ttid,t.tname from student s left join teacher t on s.tid=t.id 我复制其进入命令行，却能取出教师表的信息 求教大神，我哪里出错了，万谢！

你的Student类不就只定义了这几个字段嘛...
