struts总结

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN”             “http://struts.apache.org/dtds/struts-2.0.dtd” >
     < include file ="struts-default.xml" />
     < package name ="examples" extends ="struts-default" >    
     < action name ="Logon" class ="examples.LogonAction" >
     < result name ="success" >Hello.jsp </ result >
         < result name ="error" >Hello.jsp </ result >
</ action >
</ packeage >


访问控制器的方法:    
如果控制器的名字为LogonAction 在游览器下"http；//localhost:9090/项目名字/控制器url名字（表单action名字 ）.action"

用框架技术访问Request,Session,Response和Context 对象
HttpServletRequest request=ServletActionContext.getRequest();
HttpServletResponse response=ServletActionContext.getResponse();
HttpSession session=request.getSession();
    

Struts2 控制器将返回信息封装在一个“struts.valueStack”请求属性    ValueStack通过findValue()获取所需要返回的信息
