hibernate 双向1对1关系

维护端：

@OneToOne(fetch = FetchType.LAZY, targetEntity = com.entity.cn.News.class, cascade = CascadeType.REFRESH)@JoinColumn(name = "INFO_ID", referencedColumnName = "ID")public News getNews() {return news;}public void setNews(News news) {this.news = news;}

被维护端：

@Override@OneToOne(fetch = FetchType.LAZY, cascade=CascadeType.ALL, targetEntity = com.entity.cn.IndexInfoSet.class, optional = false)@PrimaryKeyJoinColumn(name="ID", referencedColumnName="INFO_ID")public IndexInfoSet getIndexInfoSet() {return indexInfoSet;}public void setIndexInfoSet(IndexInfoSet indexInfoSet) {this.indexInfoSet = indexInfoSet;}

其中以下必须使用 不然会报错

@PrimaryKeyJoinColumn(name="ID", referencedColumnName="INFO_ID")
