详解struts1与struts2的区别

struts1Java代码

1. //业务逻辑控制器必须继承struts1的Action类??
2. public?class?LoginAction?extends?Action???
3. {??
4. ?//处理用户请求的execute方法??
5. public?ActionForward?execute(ActionMapping?mapping,?ActionForm?form,??
6. ?????????HttpServletRequest?request,?HttpServletResponse?response)throws???
7. ????????????????AuctionException???
8. {??
9. ??//获取封装用户请求参数的ActionForm对象??
10. ??//将其强制转换为登陆用的ActionForm???
11. ??LoginForm?loginForm?=?(LoginForm)form;???
12. ??//当用户名为scott,密码为tiger时，返回成功??
13. ??if?("scott".equals(loginForm.getUsername()????
14. ???&&?"tiger".equals(loginForm.getPassword())???
15. ??{???
16. ???//处理成功，返回一个ActionForward对象??
17. ???return?mapping.findForward("success");???
18. ??}???
19. ??else???
20. ??{???
21. ???//处理失败，返回一个ActionForward对象??
22. ???return?mapping.findForward("false");???
23. ??}???
24. }??
25. }??

3）代码严重依赖struts1 API，属于侵入式设计?

struts2不在支持内建的ioc容器，而改为全面支持spring的ioc容器，以spring的ioc容器作为默认的object工厂。?
