这是action

package cn.itcast.action;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;

import com.opensymphony.xwork2.ActionContext;

import cn.itcast.service.EmployeeService;

@Controller //employeeAction
public class EmployeeAction {
@Resource EmployeeService employeeService;

public String execute(){
ActionContext.getContext().put("employee", employeeService.list());

return "list";
}

}

这是jsp页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib uri="/struts-tags" prefix="s"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>员工列表</title>
</head>
<body>
GONL:
 
<s:iterator value="#request.employee">
<s:property value="username"/> ,<s:property value="password"/> ,<s:property value="gender"/> 
</s:iterator>
 
<a href="<s:url action="manage_addUI" namespace="/employee" />">员工添加</a>
 
JSTL/EL:
 
<c:forEach items="${employee}" var="employees">
${employees.username},${employees.password},${employees.gender} 

</c:forEach>

</body>
</html>
