忘记密码发送验证码到邮箱

1.首先引入所需要的js样式

<script type="text/javascript" src="js/btnsendcode.js"></script>

<script language="javascript">
$(function() {
$.extend($.fn.validatebox.defaults.rules, {   
   equals: {   
       validator: function(value,param){   
           return value == $(param[0]).val();   
       },   
       message: '两次输入的密码不一致,请检查!'  
   }   
});
$('.loginbox').css({
'position' : 'absolute',
'left' : ($(window).width() - 692) / 2
});
$(window).resize(function() {
$('.loginbox').css({
'position' : 'absolute',
'left' : ($(window).width() - 692) / 2
});
})
$('#msform').form({   
   url:'user/reg',
   onSubmit: function(){
    return $(this).form('validate');
   },
   success:function(data){
       alert(data);
       switchDiv();
   }
});
$('.resetForm').form({   
url:'user/resetpassword', 
   onSubmit: function(){
    return $(this).form('validate');
   },
   success:function(data){   
       alert(data);
       if(data=='修改成功!'){
       switchDiv();
       }
   }
});
${message}
});
function switchDiv(){
if($('#flag').text()=='注册用户'){
$('#login').css('display','none');
$('#reg').css('display','block');
$('#flag').text('用户登录');
$('#title').text('欢迎注册Open WiFi管理系统');
}else{
$('#login').css('display','block');
$('#reg').css('display','none');
$('#flag').text('注册用户');
$('#title').text('欢迎登录Open WiFi管理系统');
}
if($('#rest').css('display')=='block'){
$('#rest').css('display','none');
}
}
function reset(){
$('#login').css('display','none');
$('#rest').css('display','block');
$('#flag').text('用户登录');
}
</script>

再看下login.jsp页面的表单内容

<form id="msform" class="resetForm" method="post"  >
<!-- progressbar -->
<ul id="progressbar">
<li class="active">填写账号</li>
<li>邮箱地址</li>
<li>输入密码</li>
</ul>
<!-- fieldsets -->
<fieldset>
<h2 class="fs-title">需要重置的账户</h2>
<h3 class="fs-subtitle">这是第一步</h3>
<input class="easyui-validatebox"  data-options="required:true,missingMessage:'请输入账号!'"  type="text" name="name" placeholder="账户" />
<input type="button" name="next" class="next action-button" value="下一步" />
</fieldset>
<fieldset>
<h2 class="fs-title">邮箱地址</h2>
<h3 class="fs-subtitle">注册账户时候的邮箱</h3>
<input class="easyui-validatebox"  data-options="required:true,validType:'email',missingMessage:'请输入E-Mail!'" type="text" id="sendemail" name="email" placeholder="E-Mail" />
<input class="easyui-validatebox"  data-options="required:true,missingMessage:'请输入验证码!'" type="text" name="checknum" value="" id="checkNum" placeholder="验证码" />
<input id="btnSendCode" type="button" value="发送验证码" onclick="sendMessage()" /></p>
<input type="button" name="previous" class="previous action-button" value="上一步" />
<input type="button" name="next" class="next action-button" value="下一步" />
</fieldset>
<fieldset>
<h2 class="fs-title">请填写新密码</h2>
<h3 class="fs-subtitle">我们将会为你保存它</h3>
<input class="easyui-validatebox"  id="resetpwd"  data-options="required:true,missingMessage:'请输入密码!'" type="password" placeholder="密码" />
<input class="easyui-validatebox" data-options="required:true,missingMessage:'请再次输入密码!'"  type="password" name="password" placeholder="确认密码" validType="equals['#resetpwd']"/>
<input type="button" name="previous" class="previous action-button" value="上一步" />
<input type="submit" class="submit action-button" value="重置"  />
</fieldset>
</form>

2.再写一下btnsendcode.js页面的内容

var InterValObj; // timer变量，控制时间
var count = 60; // 间隔函数，1秒执行
var email;
var curCount;// 当前剩余秒数
function sendMessage() {
email= document.getElementById("sendemail").value;
checknum= document.getElementById("checkNum").value;
curCount = count;
// 设置button效果，开outPrint("用户不存在,请检查是否输入正确!");始计时
$("#btnSendCode").attr("disabled", "true");
$("#btnSendCode").val("请在" + curCount + "秒内输入验证码");
InterValObj = window.setInterval(SetRemainTime, 1000); // 启动计时器，1秒执行一次
// 向后台发送处理数据
$.ajax({
type : "POST",
url : "user/sendemail",
data :"email="+email+"&checknum="+checknum,
success : function(msg) {
alert(msg);
}
});
}
// timer处理函数
function SetRemainTime() {
if (curCount == 0) {
window.clearInterval(InterValObj);// 停止计时器
$("#btnSendCode").removeAttr("disabled");// 启用按钮
$("#btnSendCode").val("重新发送验证码");
code = ""; // 清除验证码。如果不清除，过时间后，输入收到的验证码依然有效
} else {
curCount--;
$("#btnSendCode").val("请在" + curCount + "秒内输入验证码");
}
}

3.这个是Action里面的主要方法的内容

/**
* 重置密码
*/
public void resetpassword(){
try {
code=(String)getSession().getAttribute("code");
getSession().setAttribute("code", null);
//判断session里面的用户是不是null，如果为空，择是在登陆页面重置密码，如果不为null，择是登陆后修改密码
if(user==null){
//查询用户是否存在
List<Criterion> criterions = new ArrayList<Criterion>();
criterions.add(Restrictions.eq("name", name));
user = usersService.executeQueryUnique(criterions, null);
if(user==null){
outPrint("用户不存在,请检查是否输入正确!");
return;
}}
if(user.getEmail().equals(email)&&checknum.equals(code)){
user.setPassword(new MD5Code().getMD5ofStr(password));
usersService.saveOrUpdate(user);
outPrint("修改成功!");
}else {
outPrint("修改失败,请检查!");
}

} catch (Exception e) {
e.printStackTrace();
outPrint("密码修改失败");
}

}
/**
* 给邮箱发送验证码
* 获取到的是email地址和6位验证码 code
*/
public void sendemail(){
try {
String charList = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
code = "";
java.util.Random f = new Random();
for(int i=0;i<6;i++)
{
code += charList.charAt(Math.abs(f.nextInt())%charList.length());
}
getSession().setAttribute("code", code);
SendMail sendemail = new SendMail();
sendemail.setHostName("smtp.qq.com");
sendemail.setSendMailAddress("[e-mail]");
sendemail.setMailPassword("TONG88057309");
sendemail.setMailTitle("重设密码");
String[] mailAddres = {email};
sendemail.setGetMailAddress(mailAddres);
sendemail.setMailContent("您好，您在进行重设密码服务。您的验证码是："+code);

if(sendemail.send()){
outPrint("发送成功!");
}else{
outPrint("发送失败!");
}

} catch (Exception e) {
e.printStackTrace();
outPrint("发送失败!");
}
}

4.由于调用了SendMail的方法所以给出SendMail.java的内容

补充由于自己添加了两个Action方法所以需要在相关xml文件里面增加代码：

<action name="sendemail" class="com.xerxes.action.UsersAction" method="sendemail">
<result name="input">/WEB-INF/page/login.jsp</result>
<result name="login">/WEB-INF/page/login.jsp</result>
</action>
<action name="resetpassword" class="com.xerxes.action.UsersAction" method="resetpassword">
<result name="input">/WEB-INF/page/login.jsp</result>
<result name="login">/WEB-INF/page/login.jsp</result>
</action>
