import org.slf4j.LoggerFactory;
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.Component;

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

@Component
public class MailClient {
    private static final Logger logger = LoggerFactory.getLogger(MailClient.class);

    @Autowired
    private JavaMailSender mailSender;

    @Value("${spring.mail.username}")
    private String from;

    public void sendMail(String to, String subject, String content) {
        try {
            MimeMessage message = mailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(message);
            helper.setFrom(from);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(content, true);
            mailSender.send(helper.getMimeMessage());
        } catch (MessagingException e) {
            logger.error("发送邮件失败:" + e.getMessage());
        }
    }
}

测试类：

package com.now.community.community;

import com.now.community.community.util.MailClient;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = CommunityApplication.class)
public class MailTests {
    @Autowired
    private MailClient mailClient;
    @Autowired
    private TemplateEngine templateEngine;

    @Test
    public void testTextMail(){
        mailClient.sendMail("[email protected]","TEST","welcome");
    }

    @Test
    public void testHtmlMail(){
        Context context=new Context();
        context.setVariable("username","fantianzuo");
        String content=templateEngine.process("/mail/demo",context);
        System.out.println(content);
        mailClient.sendMail("[email protected]","HTML",content);
    }
