 spring springmvc hibernate(ssh)项目整合开发---邮件通信的应用

     ssh项目整合开发“注册成功时的邮件验证”与“忘记密码时通过邮件找回”两个小模块。这两个小模块我在实现与测试完毕之后，觉得其核心就在于javaMail的开发，javaMail，具体我就不介绍了，其实，就是用到了我之前博文说到的这篇博客：javaMail发送邮件（工具类开发） ，本整合项目其实用到的邮件发送工具类就是来源于它！

     但是，那只是核心的一部分而已，其实还有其他需要考虑到的，比如“如何保证验证的那条链接不会失效，如何保证验证的那条链接在点击之后再次点击时提示已经验证过了”，以及最现实的“如何组织好这一 验证用的链接”。在本整合项目中：设定“用于记录是否已经超过了链接有效日期的日期字段”、“用于记录是否已经验证过了的字段”以及“采用序列号、邮箱、用户名字节编码拼接而成的链接作为发送给邮箱的验证链接”。

     好了，说多了，都有点迷迷糊糊的了！咱们先从“忘记密码”模块入手吧！

     当然啦，我先把总体需要用到的UserController类贴完整吧（其中就包括了前面说到的用户登录）：

     点击“忘记密码”链接，出现需要填写注册时的用户名与邮箱，验证用户名与邮箱是匹配的话，就开始发送一条链接到输入的邮箱中：

     这个时候，我的邮箱就收到了一条信息：

     点进去看看：

     然后，点击里面的“找回密码”，你就可以输入新的密码，点击“确认”，即成功找回自己的密码！

     如果，此时再去那个邮箱中点击“找回密码”，则会出现“已经验证过了！”：

     这些的实现已经在上面的UserController类中贴出代码了，其中，可能会用到一些工具类，如JavaMailUtils，这一个可以在我前面的博客：javaMail发送邮件（工具类开发） 可以弄到，其他的工具类我在后面会贴出来。现在讲讲“用户注册”这个功能。点击“用户注册”，既可以进行用户注册（其中，用户名是不能重复的！）

     这时候，注册的邮箱会受到一份邮件，用于注册时候的验证：

     点击“验证信息”，即可完成信息的验证，8s后即可自动跳到首页

     最后，把pages/user里面的页面代码贴一贴吧，首先是forgetPassword.jsp：

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" ".dtd">

</head>
<body><input type="hidden" id="serverUrl" value="${tPath}" /><form><table><tr><td>用户名：</td><td><input type="text" id="userName" name="userName" /></td></tr><tr><td>邮箱：</td><td><input type="text" id="email" name="email" /></td></tr></table></form><a href="${ctx}/user/findPassword" id="findPasword">找回密码</a><br><br><%-- <a href="${ctx}/user/validateInfo?userName=linsen&email=linsenzhong@126&validateSerCode=123123123" >验证信息</a> --%>
</body>
</html>

    接着是index.jsp：

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" ".dtd">

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<body>登录成功当前用户: ${loginUser.userName}

</html>

    接着是register.jsp：

<%@ page language="java" contentType="text/html; charset=utf-8"pageEncoding="utf-8" %>
<%@ taglib prefix="c" uri="" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" ".dtd">

<body>
<input type="hidden" id="serverUrl" value="${tPath}" /><div align="center" style="padding-top: 50px;"><form><table><tr><td>用户名：</td><td><input type="text" id="userName" name="userName" /></td></tr><tr><td>密码：</td><td><input type="password" id="password" name="password" /></td></tr><tr><td>邮箱：</td><td><input type="text" id="email" name="email" /></td></tr><tr><td><input type="button" value="注册" id="regBtn"/></td><td><input type="button" value="重置" /></td></tr><tr><td></td><td id="errorInfo" style="color: #ff0000;"></td></tr></table><div id="errorTip"></div></form></div>
</body>
</html>

    然后是validateInfo.jsp：

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" ".dtd">

</head>
<body><input type="hidden" id="serverUrl" value="${tPath}" /><input type="hidden" id="userId" value="${valiUser.id}"/>验证信息 ${validateRes}<br><c:choose><c:when test="${validateRes=='验证成功'}"><form><table><tr><td>用户名：</td><td><input type="text" value="${valiUser.userName}" readonly="readonly"/></td></tr><tr><td>新密码：</td><td><input type="password" id="oldPassword" /></td></tr><tr><td>确认密码：</td><td><input type="password" id="newPassword" /></td></tr><tr><td><input type="button" value="确认" id="ensureBtn"/></td><td></td></tr></table><div id="errorTip"></div>		</form></c:when><c:otherwise><font size="12" color="#ff000">*${validateRes}</font></c:otherwise></c:choose></body>
</html>

     最后是validateRegister.jsp：

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" ".dtd">

</html>

      觉得页面的代码，不难理解，而且，其与后台的交互，用的是jquery、ajax，所以我觉得比较实用！

      好了，这两个小模块就介绍到这里吧！下面介绍一下用到的DateUtils，SystemUtils和UUIDUtils：
