如何扩充action类,从哪些方面？
如能给出好的代码，另开贴给100分

[onray]

楼主指的扩充 是什么意思
我一般会用DynamicAction 来做

[majy]

action就一个转发类，没啥搞头吧，业务逻辑写这里也不是很合适

见，小孙的精通struts.

原来是要扩展Action ，不好意思。呵呵

[mxlmwl]

应该是扩展RequestProcessor吧？action中就一个execute方法，没什么好扩充的。而且structs1.2之后的版本都是通过RequestProcessor来实行总调度的。

完成错误处理，跳转控制，减少具体action类中的代码

=======================
这是什么意思？什么错误处理？ActionError么？formbean本身不是已经进行了一层拦截了么
跳转控制用mapping.findForward，就这么一句话，你还想怎么做？

减少具体action类中的代码，这个问题问的太没水准了吧，这要看你的实际情况了啊。
一般是把业务逻辑写到Service中，action中只是简单调用业务层的方法而已，已经简化了，你还想如何简化呢？

把你的实际需求说出来让大家帮你参谋一下，你现在的这个想法首先就未必是对的。

[yanxibang]

就是要写一个action基类，完成错误处理，跳转控制，减少具体action类中的代码

建议你看看孙卫勤的 精通struct，里面有详细的介绍

最好还是把你200分收回, 自己好好找找资料.
