1 导入 jstl 的 jar 包
2. 页面中添加
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
3. 使用 jstl 遍历 employeeList 后端传过来的是一个 集合， 当动存放的是 对象
<c:if test="${empty requestScope.employeeList }"> ???????没有任何员工信息 ???</c:if> ???<c:if test="${!empty requestScope.employeeList }"> ???????<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="${requestScope.employeeList }" var="emp"> ???????????????<tr> ???????????????????<td>${emp.id }</td> ???????????????????<td>${emp.lastName }</td> ???????????????????<td>${emp.email }</td> ???????????????????<td>${emp.gender == 0 ? ‘Female‘ : ‘Male‘ }</td> ???????????????????<td>${emp.department.departmentName }</td> ???????????????????<td><a href="">Edit</a></td> ???????????????????<td><a class="delete" href="emp/${emp.id }">Delete</a></td> ???????????????</tr> ???????????</c:forEach> ???????</table> ???</c:if>jstl 遍历数据
