1.引入jar包 pom.xml

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

添加配置 application.yml 本人采用163邮箱

spring:
   mail:
     host: smtp.163.com #邮箱服务器地址
     username: ***@163.com #用户名
     password: *** #开启POP3之后设置的客户端授权码
     default-encoding: UTF-8 #编码

126邮箱配置

spring.mail.host=smtp.126.com
spring.mail.username=***.126.com
spring.mail.password=*** #开启POP3之后设置的客户端授权码
spring.mail.default-encoding=UTF-8

qq邮箱配置

spring.mail.host=smtp.qq.com
spring.mail.username=***@qq.com
spring.mail.password=*** #开启POP3之后设置的客户端授权码
spring.mail.default-encoding=UTF-8

2. 邮箱开启客户端授权码进入163邮箱，根据提示开启客户端授权码会让你输入客户端授权码，就是上面配置的密码。

3. 代码实现：创建一个借口一个普通文本方法，一个富文本方法

package com.juxinli.normandy.service;

import javax.mail.MessagingException;

public interface MailService {

  public void sendSimpleMail(String to, String subject, String content);
  
  
  public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) throws MessagingException;
}

实现接口：

package com.juxinli.normandy.service.impl;

import java.io.File;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import com.juxinli.normandy.service.MailService;

/**
 * MailService实现类
 */
@Service
public class MailServiceImpl implements MailService {

    @Autowired
    private JavaMailSender mailSender;

    @Value("${spring.mail.username}")
    private String from;
    //简单文本
    @Override
    public void sendSimpleMail(String to, String subject, String content) throws MailException {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from); // 邮件发送者
        message.setTo(to); // 邮件接受者
        message.setSubject(subject); // 主题
        message.setText(content); // 内容

        mailSender.send(message);
    }
     // 复杂文本 带图片
	@Override
	public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) throws MessagingException {
	    MimeMessage message = mailSender.createMimeMessage();
	    MimeMessageHelper helper = new MimeMessageHelper(message, true);
	    helper.setFrom(from);
	    helper.setTo(to);
	    helper.setSubject(subject);
	    helper.setText(content, true);
	    File file = new File(rscPath);
	    FileSystemResource res = new FileSystemResource(file);
	    helper.addInline(rscId, res);

	    mailSender.send(message);
	}
}

4.测试接口使用

@Test
	public void test2() throws MessagingException {
	    String to = "***@qq.com";
	    String subject = "深空之下";
	    // 此处为linux系统路径
	    String content = "天地无终极。人命若朝霞";
	    mailService.sendSimpleMail(to, subject, content);
		System.out.println("成功了");
	}
	
	@Test
	public void test3() {
	    String to = "***@163.com";
	    String subject = "今晚要加班，不用等我了";
	    String rscId = "img110";
	    String content = "<html><body><img width='250px' src=\'cid:" + rscId + "\'></body></html>";
	    // 此处为linux系统路径
	    String imgPath = "/Users/kx/WechatIMG16.jpeg";
	    try {
	        mailService.sendInlineResourceMail(to, subject, content, imgPath, rscId);
	        System.out.println("成功了");
	    } catch (MessagingException e) {
	        System.out.println("失败了");
	        e.printStackTrace();
	    }
	}

5，结果：因项目只需要简单文本这里只对简单文本进行测试，富文本没有测试过。可以自行测试，如有问题请自行改正。
