springmvc中出现前台无法遍历后台传来结果的问题

Question

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>

上边是加入的标签

${requestScope.tom }//测试可以
    ${requestScope.employees}//单独调用测试可以

    <c:if test=" ${empty requestScope.employees}" >
            没有任何员工信息
    </c:if>

    <c:if test="${!empty  requestScope.employees }">
            <table border="1" cellpadding="10" cellspacing="0">
                    <tr>
                            <th>ID</th>
                            <th>LastName</th>
                            <th>Email</th>
                            <th>Gender</th>
                            <th>Department</th>
                            <th>Edit</th>
                            <th>Delete</th>
                    </tr>
                    <c:forEach items=" ${requestScope.employees }"  var="emp">
                            <tr>
                                <td>${items[fn:trim(emp.id)]}</td>
                                <td>${items[fn:trim(emp.lastname)]}</td>
                                <td>${items[fn:trim(emp.email)]}</td>
                                <td>${items[fn:trim(emp.gender)]==0 ? 'female' :  'male'}</td>
                                <td>${items[fn:trim(emp.department.departmentName)]}</td>
                                <td><a href=" ">Edit</a></td>
                                <td><a href=" ">Delete</a></td>
                            </tr>
                    </c:forEach>
            </table>
    </c:if>

运行结果：

zhang
[Employee [id=1001, lastname=E-AA, email=[e-mail], gender=1, department=com.sxmu.entity.Department@3b8cf60f], Employee [id=1002, lastname=E-BB, email=[e-mail], gender=1, department=com.sxmu.entity.Department@79191bb0], Employee [id=1003, lastname=E-CC, email=[e-mail], gender=0, department=com.sxmu.entity.Department@79df8c75], Employee [id=1004, lastname=E-DD, email=[e-mail], gender=0, department=com.sxmu.entity.Department@34c2959c], Employee [id=1005, lastname=E-EE, email=[e-mail], gender=1, department=com.sxmu.entity.Department@68223185]]

从这个结果可以看到在页面已经拿到了这个结果，页面打印了一个表格，可是数据并没有录入进去

Answer 1

 <td>${fn:trim(emp.id)}</td> 这样试试
