FixedStarHaHa 2017-10-10 11:49:09

struct.xml:



  <package name="login" namespace="/login" extends="struts-default">

     

     

        <action name="login*" class="com.front.action.LoginAction{1}">

           <result>

               /user_login_success.jsp

           </result>

           

           

           </action>

    </package>

---------------------------------------------------------------------------------
action:
public class LoginAction1 extends ActionSupport {

private Map<String,Object> request;
private Map<String,Object> session;
private Map<String,Object> application;
@SuppressWarnings("unchecked")
public LoginAction1(){
request=(Map<String,Object>)ActionContext.getContext().get("request");//ActionContext:就是action的运行环境
session=(Map<String,Object>)ActionContext.getContext().getSession();
application=ActionContext.getContext().getApplication();

}

public String excute(){
String infor="AAAA";
System.out.println(infor);
request.put("r1", infor);
session.put("s1", infor);
application.put("a1", infor);

return "success";
}
}
-----------------------------------------
index.jsp



<form action="" name="f" method="post">

        用户名：<input type="text" name="name" />

      密码：<input type="text" name="psw" />

        <input type="button" value="submit1" onclick="javascript:document.f.action='login/login1';document.f.submit();">

</form>

------------------------------------------------------
user_login_success.jsp



<body>

      <!-- 值可以通过request.getattribute取到 -->

      <s:property value="#request.r1"/> | <%=request.getAttribute("r1") %>

      <s:property value="#session.s1" />| <%=request.getAttribute("s1") %>

      <s:property value="#application.a1" />| <%=request.getAttribute("a1") %>

      <s:debug></s:debug> 

  </body>

在user_login_success.jsp页面无法得到request.r1的值session.s1的值等
