struts formbean
理由如下：
1.由于后台数据库表字段的修改造成此formbean的修改，同时前端表现页面展现代码要修改，Action类也要跟着修改,也就是业务代码要修改，开发初期表的字段增删改是非常正常的，没有人能做到设计都是完美不用修改的。
2.有些人美其名曰formbean是面向对象，面向对象造成了开发与维护的如此繁琐，为OO而OO，得不偿失。最需要OO的地方是业务规则以及框架。
我们需要什么：
1.struts的action控制机制还是要保留，tag部分可以彻底扔掉。
2.在表现层与业务逻辑层我们传递的就是VO(数值对象)而已。需要的只是一个数据存放的容器而已，能做到通用就行了。难道非要写成bean.getXXX()的形式才叫OO么？
3.对于刚刚接触struts的人，或者不喜欢用标签的人，怎么样才能更好的完成协作开发呢？
我们只需要他们会html,java就可以了,让标签们见鬼去吧，让formbean见鬼去吧。
改进方案：
1.一个通用的action ,BaseAction extendsAction.负责完成http request,http session的参数收集与整理，形成一个通用的form,BaseForm extends ActionForm.
此BaseForm就可以传递到表现层了。
2.如果你有些地方需要使用标签，可能因为您偏爱或者习惯使用struts标签了，所以你可以继承这个BaseForm,然后添加你的方法和属性。而对于不习惯的人，则可以使用方案1的逻辑了。
3.BaseAction最好能实现几个通用功能，比如分页，普通查询，修改，插入等，这样各个实现的业务action在代码上减少很多,维护就更简单了。
代码实现：

public class OrderAction extends BaseAction {

整个配置文件就一个formbean而已
