经过三个月。自己写的站点(后台运营支撑平台)上线了。投入使用，执行良好。近期站点门户也完活了，如今即将上线。可是发现了一个问题。前后台会有些文件来往。就是前台要用到后台的文件资源。
因为前后台是分server部署的，两个不同的域名。所以解决此问题。非常棘手。
没办法。想了用java jcifs ，可是时间紧，没用过，所以搁浅。最蠢的办法。前后台合并！
合并后，遇到了两个奇葩问题
1。
后台页面不能连续高速刷新(F键)。不然立刻崩溃。

2.关于数据源,因为出现了上述错误。我尝试更换数据源。c3p0 和 JDBC 还真的有点差别。c3p0是不能连续高速的刷新(F5键) ，而jdbc 是登录系统后，一旦和数据库打交道立刻崩溃！ 对此，我笑了
3.出现此问题的。我的操作就是讲两个项目的包都放在项目的src 下，并且保证它们之间没有反复的命名。SSH框架下正常启动。二就是说项目代码。文件配置全然没没问题。
没办法，我又一咬牙，将后台的全部包去掉，将同功能的东西放在了一个包下，比如 接口 ,实体类,实现类。后台启动，測试。没问题了！
！
以上经验让我非常无语，至今无解！
望 路 过 大 鸟 释 疑！
