严重: Developer Notification (set struts.devMode to false to disable this message)

小红_Su 2016-03-08 01:56:09

代码如下

这是struts.xml



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

    "http://struts.apache.org/dtds/struts-2.0.dtd">

 

<struts>

 

  <constant name="struts.devMode" value="true" />

 

  <package name="basicstruts2" extends="struts-default">

    <action name="index">

      <result>/index.jsp</result>

    </action>

         

    <action name="login" class="shopping.LoginTest" method="execute">

      <result name="userbe">/shoppingcart.jsp</result><!-- 用户页面 -->

      <result name="manager">/managercart.jsp</result><!-- 管理员页面 -->

      <result name="usernull">/login.jsp</result>

    </action>

  </package>

</struts>

这是LoginTest类



package shopping;



import java.sql.*;



import java.util.Map;

import org.apache.struts2.interceptor.SessionAware;



import dao.*;

import bean.*;



import com.opensymphony.xwork2.ActionSupport;



public class LoginTest extends ActionSupport implements SessionAware {

	private String username;

	private String password;

	

	private Map<String,Object> session;

	

	public String getUsername() {

		return username;

	}



	public void setUsername(String username) {

		this.username = username;

	}



	public String getPassword() {

		return password;

	}



	public void setPassword(String password) {

		this.password = password;

	}



	//验证登录信息

	public String execute(){

		UserDao dao = new UserDao();

		UserBean user = new UserBean();

		user = dao.selectUser(username);

		//验证

		if(user!=null && password.equals(user.getPassword())){

			session.put("use",user); //登录后将当前user信息保存到session中

			System.out.println(user.getRole());

			if(user.getRole().equals("user")){

				return "userbe";

			}else{

				return "manager";

			}

		}else{

			return "usernull";

		}

	}

	

	@Override

	public void setSession(Map<String, Object> session) {

		// TODO Auto-generated method stub

		this.session = session;

	}

}

跳转后jsp是shoppingcart.jsp



 <body>

  ${sessionScope.user.role}

  </body>

执行后跳转一切正常，但是session上并没有传到值上去，也打印不出来，控制台也提示了错误如下

严重: Developer Notification (set struts.devMode to false to disable this message):
Unexpected Exception caught setting 'role' on 'class shopping.LoginTest: Error setting expression 'role' with value ['user', ]

跪求大神帮忙解决一下，今天等着用，明天要交，拜托了
