Springboot企业邮箱发送邮件

一：引入依赖

<!--mail-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>

二：编写工具类

package com.ambul.core.config;

import com.sun.mail.util.MailSSLSocketFactory;

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.security.GeneralSecurityException;
import java.util.Date;
import java.util.Properties;

public class SendMail {
    private static  Properties prop = null;
    private static MimeMessage mimeMessage;
    final static String E_ACCOUNT = "xx企业邮箱账号";
    final static String E_PAW = "密码";

    private static void init(){
        try {
            prop = new Properties();
            prop.setProperty("mail.transport.protocol", "smtp");
            prop.setProperty("mail.smtp.host", "smtp.exmail.qq.com");    //服务器
            prop.setProperty("mail.smtp.port", "465");                    //端口
            prop.setProperty("mail.smtp.auth", "true");                    //使用smtp身份验证

            //使用SSL，企业邮箱必需！
            //开启安全协议
            MailSSLSocketFactory sf = null;
            try {
                sf = new MailSSLSocketFactory();
                sf.setTrustAllHosts(true);
            } catch (GeneralSecurityException e1) {
                e1.printStackTrace();
            }
            prop.put("mail.smtp.ssl.enable", "true");
            prop.put("mail.smtp.ssl.socketFactory", sf);
            //
            //获取Session对象
            Session session = Session.getDefaultInstance(prop,new Authenticator() {
                //此访求返回用户和密码的对象
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    PasswordAuthentication pa = new PasswordAuthentication(E_ACCOUNT, E_PAW);
                    return pa;
                }
            });
            //设置session的调试模式，发布时取消
            //session.setDebug(true);
            mimeMessage = new MimeMessage(session);
            mimeMessage.setFrom(new InternetAddress(E_ACCOUNT,E_ACCOUNT));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * 发送邮件
     */
    public static void mailSend(String recEmail,String subject,String text){
        try {
            if(prop == null){
                init();
            }

            mimeMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(recEmail));
            mimeMessage.setSubject(subject);        //设置主题
            mimeMessage.setSentDate(new Date());
            mimeMessage.setText(text);         //设置内容
            mimeMessage.saveChanges();
            Transport.send(mimeMessage);        //发送
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

三：测试代码

@Test
    public void test12() {
        SendMail.mailSend("[e-mail]", "异常通知", "中央缓存宕机");
    }

四：邮件消息
