appfuse 2.1 数据表 反向工程二次开发错误处理

appfuse官方说可以使用mvn appfuse:gen命令根据pojo或者数据表直接生成相应的DAO到表示层的全部文件，但在2.1.0struts-basic下实测是不行的，会出现莫名其妙的错误。

首先参考网上appfuse2.1.0的相关文章除掉一大片的错误直到可以BUILD SUCCESSFUL

接着参照http://blog.csdn.net/zhulin902/article/details/3935536(貌似这篇文章里面说的重复ID不怎么正确，不过我也没深究……)这篇文章做到mvn appfuse:gen-model这一步生成相应的pojo，但再往下一步做就会出错了，提示找不到User之类。这时候再运行原先可以通过的install和jetty:run虽然可以运行，但是会报JNDI错误。

根据之前反映的错误http://appfuse.547863.n4.nabble.com/problem-with-hibernate-tutorial-imports-for-annotations-td2541421.html发现是在之前的过程中莫名奇妙的被修改了hibernate.cfg.xml文件，把里面多出来的 name="" 去掉以后一切就恢复原样了。

顺便记录一下自己犯的bug免得自己再犯，写POJO的时候引用外部对象记得把原先的字段field删掉，老想着既可以看到ID值有可以引用会带来好多错误的……

DAO往上的层个人建议还是勤快点手写吧，前面那个错误搞了N久才解决掉，貌似2.1.0bug足够多…………
