Question

我正在建立两个实体之间的关系

@Entity
@Table(name = "DEPARTMENT")
public class Department{
    @Id
    private Long id;

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

    @Column(name = "DEPT_NAME")
    private String deptNAme;
}



@Entity
@Table(name = "EMPLOYEE")
public class Employee{
    @Id
    private Long id;

    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name = "DeptId")    
    private Department dept;

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

    @Column(name = "EMP_NAME")
    private String empName;
}

问题是表上的员工与dept的ID有关，我想将其与deptId链接起来怎么办？

Answer 1

使用

@JoinColumn(name = "DeptId" , referencedColumnName = "DEPT_ID") ;

如何与休眠中的特定列关联？
