- 使用Properties对象封装服务器信息
更多可以去 这里 了解要发送邮件,就要和邮件服务器通信,所以需要服务器信息;
常见的有:
mail.smtp.host //主机名
mail.smtp.auth //是事进行身份验证
mail.smtp.port //邮件服务器端口号
mail.smtp.socketFactory.class //ssl工厂类
mail.smtp.socketFactory.port //ssl接口 - 获取session对象
一般在这里时给在后面的参数中给出一个验证器 Authenticator对象//不共享
session session= Session mailsession = Session.getInstance(props,null);
//单例,共享
Session mailsession = Session.getDefaultInstance(props,null);
- 用message封装邮件信息
- 获取Transport对象发送邮件
package cn.mail;
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;
public class MailSender {
public void send() throws Exception{
//设置邮件信息
Address formMail = new InternetAddress("zhangsan@126.com");
Address toMail = new InternetAddress("1001000@qq.com");
String subject = "测试邮件";
String content="测试邮件的内容";
/*设置邮件服务器信息*/
Properties props=System.getProperties();
props.put("mail.smtp.host", "smtp.126.com");//主机
props.put("mail.smtp.auth", "true");//做身份验证
//获取session对象
Session mailsession=Session.getInstance(props,new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
//返回 用户名 与 密码
return new PasswordAuthentication("zhangsan@126.com", "zhansanpass");
}
});
/*设置删除件信息*/
Message msg=new MimeMessage(mailsession) ;
msg.setFrom(formMail);//发件人
msg.addRecipient(RecipientType.TO, toMail);//收件人
msg.setSubject(subject);//主题
msg.setContent(content, "text/html;charset=utf-8");//正文及MIME,此处指定编码有助于防止乱码
msg.setSentDate( new Date() );//发送时间
/*获取Trans并发送*/
Transport trans= mailsession.getTransport("smtp");
trans.send(msg, msg.getAllRecipients());//发送组所有收件人
trans.close();
}
public static void main(String[] args) {
MailSender sender=new MailSender();
try {
sender.send();
} catch (Exception e) {
e.printStackTrace();
}
}
}
- 创建邮件发送类
package mail.service;
import mail.entity.MailInfo;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
/**
* 邮件发送业务
*
* @author Administrator
*
*/
public class SimpleMailServiceImpl implements IMailService {
// 邮件发送器
private JavaMailSenderImpl sender;
@Override
public void sendMail(MailInfo mail) throws Exception {
// 建立邮件消息
SimpleMailMessage mailMessage = new SimpleMailMessage();
mailMessage.setTo("xxxxxxxx@qq.com");// 收件人
mailMessage.setFrom("xxxxxx@qq.com");// 发件人
mailMessage.setSubject("测试简单文本邮件发送！ ");// 主题
mailMessage.setText(" 测试我的简单邮件发送机制！！ ");// 内容
// 发送邮件
sender.send(mailMessage);
System.out.println(" 邮件发送成功.. ");
}
public JavaMailSenderImpl getSender() {
return sender;
}
public void setSender(JavaMailSenderImpl sender) {
this.sender = sender;
}
}
- 在spring的配置文件中配置MailSender实现Bean
完成以上步骤就可以发简单邮件了<?xml version="1.0" encoding="UTF-8"?>

- MailSender用JavaMailSender这个实现类
private JavaMailSender sender;
- MailMessage 用 MimeMessage这个实现类
//创建 复杂邮件内容对象
MimeMessage msg=sender.createMimeMessage(); - 设置MimeMessage中的内容时,用工具类 MimeMessageHelper
//创建 复杂邮件内容 帮助 对象
MimeMessageHelper helper=new MimeMessageHelper(msg,true,encoding);
....//设置发件人
helper.setFrom(mail.getFromAddr()); - 处理附件文件名乱码用 MimeUtility类
//用 MimeUtility进行转码防止中文文件名乱码
helper.addAttachment( MimeUtility.encodeWord(file.getName()), file);
