在Maven项目中关于SSM框架中邮箱验证登陆

1、你如果要在maven项目中进行邮箱邮箱验证，你首先要先到pom.xml文件中配置mail.jar,activation.jar包

   <dependency>
       <groupId>javax.mail</groupId>
       <artifactId>mail</artifactId>
        <version>1.4</version>
       </dependency>

       <dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1.1</version>
</dependency>

2、然后你可以写一个简单的jsp页面进行测试

<form action="<c:url value='/MailLogin/mail'/>" method="post">

  	 邮箱验证<input type="text" name="mail"/><br/><br/>
  	      <input type="submit" value="注册"/>
  	 </form>

　　

然后在springMVC下面注入@Controll

@Controller
@RequestMapping("/MailLogin")
public class mailLogin {

    @RequestMapping("/mail")
    public String mailSucc(HttpServletRequest request) throws Exception{

         String toEMAIL = request.getParameter("mail");         //对方邮箱
          String TITLE = "邮箱注册成功ing了";       //标题
          String CONTENT =toEMAIL+"你成功激活了！！！";        //内容
          JavaEmailSender.sendEmail(toEMAIL, TITLE, CONTENT);
        return "/mailSucc";

    }

之后就写邮件发送代码

package cn.hncu.utils;
import java.util.Date;
import java.util.Properties;

import javax.mail.Address;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import com.sun.mail.util.MailSSLSocketFactory;
public class JavaEmailSender {

     public static void sendEmail(String toEmailAddress,String emailTitle,String emailContent)throws Exception{
            Properties props = new Properties();

            // 开启debug调试
            props.setProperty("mail.debug", "true");
            // 发送服务器需要身份验证
            props.setProperty("mail.smtp.auth", "true");
            // 设置邮件服务器主机名
            props.setProperty("mail.host", "smtp.qq.com");
            // 发送邮件协议名称
            props.setProperty("mail.transport.protocol", "smtp");

            /**SSL认证，注意腾讯邮箱是基于SSL加密的，所有需要开启才可以使用**/
            MailSSLSocketFactory sf = new MailSSLSocketFactory();
            sf.setTrustAllHosts(true);
            props.put("mail.smtp.ssl.enable", "true");
            props.put("mail.smtp.ssl.socketFactory", sf);

            //创建会话
            Session session = Session.getInstance(props);

            //发送的消息，基于观察者模式进行设计的
            Message msg = new MimeMessage(session);
            msg.setSubject(emailTitle);
            //使用StringBuilder，因为StringBuilder加载速度会比String快，而且线程安全性也不错
            StringBuilder builder = new StringBuilder();
            builder.append("\n"+emailContent);
            builder.append("\n时间 " + new Date());
            msg.setText(builder.toString());
            msg.setFrom(new InternetAddress("你的邮箱号码"));

            Transport transport = session.getTransport();
            transport.connect("smtp.qq.com", "你的邮箱号码", "你的登陆密码、（你开启POP3/SMTP服务申请的独立密码）");
            //发送消息
            transport.sendMessage(msg, new Address[] { new InternetAddress(toEmailAddress) });
            transport.close();
          }

        }

如果你没有设置开启SSL，那么你的程序就会报错，就会出现SMTP服务连接失败，还有就是你的QQ邮箱中的POP3/STMP服务要设置打开，你在测试发送给其他邮箱的时候，你的POP3/STMP服务也要打开，不然就会访问不了，报出连接失败的错误信息来！你要查看你自己的是否发送成功可以自己登陆另一个邮箱去查看，也可以去查看你控制台输出的消息：

   /**SSL认证，注意腾讯邮箱是基于SSL加密的，所有需要开启才可以使用**/
            MailSSLSocketFactory sf = new MailSSLSocketFactory();
            sf.setTrustAllHosts(true);
            props.put("mail.smtp.ssl.enable", "true");
            props.put("mail.smtp.ssl.socketFactory", sf);

下面是我发送成功之后控制台输出的消息：

如果你没又没进行设置SSL的话默认的这个端口就是25    ----》
