出于某种原因，我无法再部署我的项目了。
我收到以下错误消息：

我尝试运行maven clean和maven update项目，但这根本没有效果。导致此错误的原因是什么，我该如何解决？
答案 0 :(得分：2)
我忘了将@OneToMany添加到其中一个集合中。
编辑：我刚刚注意到我获得了这个问题的金奖（“着名问题”），我觉得我不值得。所以我想完成我的答案。我猜大多数人都在继续寻找Jboss服务异常。异常可能意味着什么 - 您必须识别项目的问题。我没有正确读取Stacktrace。它说：
org.hibernate.loader.MultipleBagFetchException: cannot simultaneously fetch multiple bags
因此，寻找该异常将有助于确定问题。在我的情况下，我搞砸了hibernate注释。阅读你的例外情况！
