@OneToOne与@JoinColumn的双向映射

您的代码应为：

@Entitypublic class Person implements Serializable {    @Id Integer id;    @oneToOne    @JoinColumn(name = "id")    Job myJob;}@Entitypublic class Job implements Serializable {    @Id Integer id;    @oneToOne(mappedBy = "myJob")    Person currentWorker;}

（尝试从工作中删除重复的列’person_id’）

或其他共享主键的方法：

@Entitypublic class Person {    @Id Integer id;    @oneToOne(cascade = CascadeType.ALL)    @PrimaryKeyJoinColumn    Job myJob;}@Entitypublic class Job {    @Id Integer id;}
