结贴律过低，不予解答。

[努力新人]

为什么呀，我真的好急呀，都搞了一天了。

[努力新人]

此贴成了百度搜索第一，结果还是未解决。。。。汗。。。

[xinghen88]

楼主该结贴了，要不就真的没人给你回答了！你看看你的实体类是否实现了Serializable接口：implements Serializable，并且添加了默认构造和含有参数的构造，或者是否进行了getter/setter方法。

[努力新人]

哈哈。。。。我终于知道是什么问题了。
两天，两天终于找到原因了。

[xiaobaowan]

对于这种只求别人帮忙，自己解决了又不说出来的人真是深恶痛绝！！！

[十年一剑般的男人]

照报的错来看应该是读取配置文件的时后报的错，或者是映射文件！
我们又不知道你具体的代码，所以也不能体出太具体的答复！

顶6楼，bs中

[Maakey]

艹，你妹的，知道答案了又不把答案弄出来，你个2B，强烈看不起！

[tank98zhang]

是Id问题，Entity必须定义一个Id。 顺便鄙视一下楼主，自己解决了也不说，害得我搞了好几个小时才发现是什么问题，去死吧，骂了隔壁！
