java微信平台，发源码

最近写了一个微信平台的架构，采用servlet + spring3.0 + hibernate4.1。整体架构由我负责建设，我尽可能的把业务模块分出来。趁着刚搭好的框架，留着这版。代码是大部份都由其他成熟框架直接 copy过来整合，去掉了一些没用的配置。部分我加入的设计也都是自己经过长时间项目提炼出来的，所有代码稳定性大可放心，并且难度不大。源码我也贴网上，希望有人帮我一起完善一下！不足处也请批评指正。

贴出部分代码，用到了部分设计模式，代码可读性比较好。没什么技术含量，里面有一些涉及微信平台的业务代码可能会有点难懂，如果您认为还不错，那就点个赞。如果认为还值得改进，那也麻烦提出来，我也近期慢慢改进。

代码贴在这里，如果有人愿意一同学习进步，后期就放到github上面去，现阶段我将持续改进。
