idea-ssm汽车修配厂（七）通过邮件找回密码(线程池)

在邮箱中把：POP3/SMTP服务，IMAP4服务/SMTP服务开启
spring整合 spring-context-support 使用smtp协议
maven

   <!--邮箱 -->

注意一定要改spring-mybatis

task任务类

package com.xiupeilian.carpart.task;


import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;


public class MailTask implements Runnable {
    private JavaMailSenderImpl mailSender;
    private SimpleMailMessage mailMessage;


    public MailTask(JavaMailSenderImpl mailSender, SimpleMailMessage mailMessage) {
        this.mailSender = mailSender;
        this.mailMessage = mailMessage;
    }

    @Override
    public void run() {
        mailSender.send(mailMessage);

    }
}

发送邮箱，我们要注入JavaMailSenderImpl mailSender;

//发送邮件到用户邮箱  1s  将同步流程异步化 可以采用多线程
			SimpleMailMessage message = new SimpleMailMessage();
			message.setFrom("tu18610679287@sina.com");
			message.setTo(user.getEmail());
			message.setSubject("修配连汽配市场密码找回功能:");
			message.setText("您的新密码是" + password);
			/**
			 创建一个任务，交给线程池就可以了.
			 **/
			MailTask mailTask = new MailTask(mailSender, message);
			//让线程池去执行该任务就可以了
			executor.execute(mailTask);

			response.getWriter().write("2");

后端ajax请求

function getPwd(){
var index = parent.layer.getFrameIndex(window.name);
var email=$("#email").val();
var username=$("#username").val();
if(email!=""&&username!=""){
$.ajax({
    url:"${ctx}/login/getPassword",    //请求的url地址
    async:true,//请求是否异步，默认为异步，这也是ajax重要特性
    data:{"email":email,"loginName":username,},    //参数值
    type:"post",   //请求方式
    success:function(data){
          if(data=='2') {
              alert("恭喜你，新密码已发送到你邮箱");
              parent.layer.close(index);
          }else if(data=='1'){
              alert("账号邮箱不匹配!");
          }

      
    },
});
}else{

alert("用户名和邮箱不能为空");
}
}
</script>
