ssh整合 Action中的MAP到Jsp页面

这是Action

import java.util.Map;
import org.apache.struts2.interceptor.RequestAware;

import com.opensymphony.xwork2.ActionSupport;
import ssh.www.service.EmployeeService;
public class EmployeeAction extends ActionSupport implements RequestAware{

private static final long serialVersionUID = 1L;

private EmployeeService employeeService;

public void setEmployeeService(EmployeeService employeeService) {
    this.employeeService = employeeService;
}

public String list(){

    System.out.println("List Action");

    request.put("aa", employeeService.getAll());
    return "list";
}

private Map<String,Object> request;
@Override
public void setRequest(Map<String, Object> arg0) {

    this.request = arg0;

}

}
这是JSP
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Insert title here

employee list page

没有任何员工信息

/s:if

/s:iterator

ID	LASTNAME	EMAIL	BIRTH	CREATETIME	DEPT
${id }	${lastName }	${email }	${birth }	${createTime }	部门

/s:else

没有接受到Action的数据
