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

有什么建议可以解决这个问题吗？对我来说，映射是正确的，也因为它是由hibernate自动生成的
答案 0 :(得分：1)
好的！我认为这是一个Hibernate BUG。我发现了这个
答案 1 :(得分：0)
您应该将TEvents变量名称从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;
}
.....
}
答案 2 :(得分：0)
请在class TEventsDetails的以下行中定义列的名称，因为您已定义TEventsDetails表的哪些列与TEvents表相关联。
@JoinColumn(name = "EVENT_ID")
