发送邮件工具类

MailUtis.java

package cn.stylefeng.guns.utils;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

@Component
public class MailUtil {

    @Autowired
    private JavaMailSenderImpl javaMailSender;

    public static MailUtil mailUtil;

    @PostConstruct
    public void init(){
        mailUtil=this;
        mailUtil.javaMailSender=this.javaMailSender;
    }

       
    public static void sendMail(){
        SimpleMailMessage mailMessage=new SimpleMailMessage();
        mailMessage.setSubject("测试");   #主题
        mailMessage.setText("aaa");      #发送的内容
        mailMessage.setTo("[email protected]");   #发送给谁邮箱地址
        mailMessage.setFrom("[email protected]"); #发送人，这里与yml配置的username一样
        mailUtil.javaMailSender.send(mailMessage);
    }

    //发送附件代码　
public static void sendMailAttach() {
    MimeMessage mimeMessage=mailUtil.javaMailSender.createMimeMessage();
    MimeMessageHelper helper= null;
    try {
        helper = new MimeMessageHelper(mimeMessage,true);
        helper.setSubject("测试");
        helper.setText("aaa",true);   //发送含有html代码的内容
        helper.setTo("[email protected]");
        helper.setFrom("[email protected]");

        helper.addAttachment("1.jpg",new File("C:\\Users\\Pictures\\1.jpg"));  发送附件 可以多个，前面是附件名称，后面是附件绝对路径
        helper.addAttachment("2.jpg",new File("C:\\Users\\Pictures\\1.jpg"));
    } catch (MessagingException e) {
        e.printStackTrace();
    }

    mailUtil.javaMailSender.send(mimeMessage);
　　}
