　　删除功能实现，对应controller类中的代码如下所示：

@RequestMapping(value="/{username}/delete",method=RequestMethod.GET)
public String delete(@PathVariable String username) {
    users.remove(username);
    return "redirect:/user/users";
}

　　在列表页面添加删除某条数据的链接，对应添加如下代码：

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>用户列表</title>
</head>
<body>
<a href="add">添加</a>
    <c:forEach items="${users}" var="um" >
    <a href="${um.value.username}">${um.value.username }</a>
        ----${um.value.nickname }
        ----${um.value.password }--<a href="${um.value.username }/update">修改</a>
        ----${um.value.email }
        <a href="${um.value.username }/delete">删除</a><br/>
    </c:forEach>
</body>
</html>
