我有2个表映射到休眠中的实体类,如下所示,

EmployeeEmployeeDetails表之间存在一对多关系,在EmployeeDetails表中有2个不同的列映射回EmployeeleadEmpIdmanagerEmpId表,除了与empId列。

@Entity
@Table(name = "Employee")
public class Employee {

    @Id
    @Column(name = "empId")
    private String empId;

    @Column(name = "name")
    private String name;

    @Column(name = "designation")
    private String designation;

    @OneToMany(mappedBy = "empId", cascade = CascadeType.ALL)
    private List<EmployeeDetails> EmployeeDetails;
}


@Entity
@Table(name = "EmployeeDetails")
public class EmployeeDetails {

    @Id
    @Column(name = "empDetailsId")
    private String empDetailsId;

    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name = "empId")
    private Employee empId;

    @Column(name = "project")
    private String project;

    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name = "leadEmpId")
    private Employee leadEmpId;

    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name = "managerEmpId")
    private Employee managerEmpId;
}


如下所示,有一个更新查询用于更新managerEmpId中的EmployeeDetails

@Modifying
@Query("update EmployeeDetails p set p.managerEmpId = ?1 where "
        + "p.leadEmpId.name = ?2 and "
        + "p.leadEmpId.designation = ?3")
@Transactional
int updateEmployeeDetails(Employee employee, String name, String designation);


如果上述方法使用正确的数据执行,则获取以下异常。

我们不能通过传递父属性来过滤子表行吗,或者它们在更新查询中有问题吗?

最佳答案

正如Deinum M在评论中写道:

managerEmpId的类型为Employee,而不是EmployeeDetails
