最近在维护旧系统的时候，发现旧系统的可读性和高重复性的众多问题。但是针对原有的系统在不维护的时候是满足用户的使用，也就可以说旧系统适合在维护前的那个阶段。任何系统都有那么一个阶段。没有什么系统开发完后就不需要去维护。因此就不多说可读性的问题了，这里主要根据重构进行总结。
我相信很多IT界的朋友应该都或多或少有听说《重构》这本书。这里我也是根据读了这本书结合一些想法进行总结。

基于Struts2的开发，如果没有足够的经验和规范做支撑，并不能带很多的好处.
1).Action类及Action Name的命名规范
Action类的后缀统一加上"Action",
Action的Name与类的名称保存一致，但不要"Action"的后缀。
这样是为了通过Action的调用url,很方便的找到Action类。
<action name="searchUser"
class="com.demo.search.action.SearchUserAction">
&l ...
