问题出在哪里？为什么一个可行而另一个不可行？ 我动脑筋了几个小时，没有任何成功……任何帮助将不胜感激。
答案 0 :(得分：0)
问题出在休眠状态。我对数据库表和相关传输对象进行了一些更改。但是对于事件传输对象，我必须实现序列化。然后一切正常。
我的问题是为什么构建过程不会失败并且Hibernate不会抱怨其他已更改（可序列化）且仅针对事件表的传输对象？
答案 1 :(得分：0)
此转移对象（事件）发生了这种情况，因为 第二列用@Id而不是@Basic注释。所以这创造了一个 composite-id 会导致序列化错误。通过替换@Id @Basic项目在第二列/字段中的注释正常构建 没有实现Serializable。
