1、在pom.xml中添加maven依赖

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

2、在application.properties文件中添加邮件相关配置

#邮件配置
    spring.mail.host=邮件服务器地址
    spring.mail.username=用户名
    spring.mail.password=密码
    spring.mail.default-encoding=UTF-8
    #登录服务器是否需要认证
    spring.mail.properties.mail.smtp.auth=true
    #SSL证书Socket工厂
    spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
    #使用SMTPS协议465端口
    spring.mail.properties.mail.smtp.socketFactory.port=465
     
    #显示在收件人邮箱里面的发件人名称
    spring.mail.self.username=用户名

3、编写邮件发送代码：MailSendService.java

package com.ldy.bootv2.demo.service;
 
 import java.io.File;
 import java.util.List;
 
 import javax.mail.MessagingException;
 import javax.mail.internet.InternetAddress;
 import javax.mail.internet.MimeMessage;
 import javax.mail.internet.MimeMessage.RecipientType;
 
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.beans.factory.annotation.Value;
 import org.springframework.mail.javamail.JavaMailSender;
 import org.springframework.mail.javamail.MimeMessageHelper;
 import org.springframework.stereotype.Service;
 import org.springframework.util.StringUtils;
 
 /**
 * @类名: MailSender 
 * @描述: 邮件发送 
 */
 @Service
 public class MailSendService {
 	
 	@Autowired
 	JavaMailSender mailSender;
 	
 	//发件人名称设置
 	@Value("${spring.mail.self.username}")
 	private String sendUser;
 	
 	public void sendEmail(String toMail, String title, String content) throws MessagingException {
 		final MimeMessage mimeMessage = mailSender.createMimeMessage();
 		final MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
 		message.setFrom(sendUser);
 		message.setTo(toMail);
 		message.setSubject(title);
 		message.setText(content);
 		 
 mailSender.send(mimeMessage);
 }
 	
 	/**
 	 * @方法名: sendSimpleMail 
 	 * @描述: 发送普通文本格式的邮件 
 	 * @param toMail 收件人，多个用英文格式逗号分隔
 	 * @param replyTo 抄送人，多个用英文格式逗号分隔
 	 * @param title 邮件主题
 	 * @param content 邮件内容
 	 * @param flies 附件
 	 * @throws Exception
 	 */
 	public void sendSimpleMail(String toMail, String replyTo, String title, String content, List<File> files) throws Exception {
 		final MimeMessage mimeMessage = mailSender.createMimeMessage();
 		final MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
 		helper.setFrom(sendUser);
 		helper.setSubject(title);
 		helper.setText(content);
 		
 		//设置多个收件人
 		String[] toAddress = toMail.split(",");
 		helper.setTo(toAddress);
 		
 		//设置多个抄送
 		if(!StringUtils.isEmpty(replyTo)) {
 			//helper.setReplyTo(replyTo);
 			InternetAddress[] internetAddressCC = InternetAddress.parse(replyTo); 
 			mimeMessage.setReplyTo(internetAddressCC);
 		}
 		
 		//添加附件
 		if(null != files) {
 			for (File file : files) {
 				helper.addAttachment(file.getName(), file);
 			}
 		}
 		
 		mailSender.send(mimeMessage);
 	}
 	
 	/**
 	 * @方法名: sendHtmlMail 
 	 * @描述: 发送HTML格式的邮件 
 	 * @param toMail 收件人，多个用英文格式逗号分隔
 	 * @param replyTo 抄送人，多个用英文格式逗号分隔
 	 * @param title 邮件主题
 	 * @param htmlContent 邮件内容
 	 * @param files 附件
 	 * @throws Exception
 	 */
 	public void sendHtmlMail(String toMail, String replyTo, String title, String htmlContent, List<File> files) throws Exception {
 		final MimeMessage mimeMessage = mailSender.createMimeMessage();
 		final MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
 		helper.setFrom(sendUser);
 		helper.setSubject(title);
 		helper.setText(htmlContent, true);
 		
 		//设置多个收件人
 		String[] toAddress = toMail.split(",");
 		helper.setTo(toAddress);
 		
 		//设置多个抄送
 		if(!StringUtils.isEmpty(replyTo)) {
 			//helper.setReplyTo(replyTo);
 			InternetAddress[] internetAddressCC = InternetAddress.parse(replyTo); 
 			mimeMessage.setRecipients(RecipientType.CC,internetAddressCC);
 		}
 		
 		//添加附件
 		if(null != files) {
 			for (File file : files) {
 				helper.addAttachment(file.getName(), file);
 			}
 		}
 		
 		mailSender.send(mimeMessage);
 	}
 	
 }

完成上面的代码后，在发送邮件的java类里面注入MailSendService，直接调用对应的方法即可
