Java Hibernate:中的未知mappedBy:，引用的属性未知：

我正在尝试映射我的表以使用Hibernate，但是在启动测试时出现了这个错误

有什么解决这个问题的建议吗？对我来说，映射是正确的，还因为它是由hibernate自动生成的

您应该将TEvents变量名从TEvents更改为TEvents：

public class TEventsDetails implements java.io.Serializable {

.....

private TEvents tEvents;

public TEvents getTEvents() {
    return this.tEvents;
}

public void setTEvents(TEvents TEvents) {
    this.tEvents = TEvents;
}
.....

---

}

请在

类TEventsDetails

的下一行中定义列的名称，因为您已经定义了TEventsDetails表中与TEvents表关联的列

@JoinColumn(name = "EVENT_ID")

好的！我想这是一只冬眠虫。我找到了这个

私有TEventsDetails TEventsDetails；的映射是什么？另外，最好是以小写字母开始变量名…Hibernate代码生成完成了这项工作，我同意你的看法。要回答您的问题：@OneToOne（fetch=FetchType.LAZY，mappedBy=“tEvents”）public-TEventsDetails-getEventsDetails（）{返回this.TEventsDetails；}我做到了，但是刚刚在SessionFactory创建中更改的错误失败了。org.hibernate.AnnotationException:未知映射在：it.addvalue.mam.fpk.alertengine.mapping.TEvents.TEvents详细信息中，引用的属性未知：it.addvalue.mam.fpk.alertengine.mapping.TEvents详细信息。TEvents它仅与我执行的事件ID关联，但是没有任何改变@PrimaryKeyJoinColumn（name=“EVENT\u ID”）我已经更新了我的答案，只需使用@JoinColumn（name=“EVENT\u ID”）谢谢你的回复，但没有任何改变。我想是冬眠虫。检查这个

public class TEventsDetails implements java.io.Serializable {

.....

private TEvents tEvents;

public TEvents getTEvents() {
    return this.tEvents;
}

public void setTEvents(TEvents TEvents) {
    this.tEvents = TEvents;
}
.....

@JoinColumn(name = "EVENT_ID")
