这是4中发送邮件的方式
public interface SendMailService {
//简单邮件
public void sendSimpleMail(String to,String centent,String subject);
//html邮件
public void sendHtmlMail(String to,String subject,String content);
//带附件的邮件
public void sendAttachmentMail(String to,String subject,String content,String filePath);
//带静态资源文件的邮件
public void sendInlineResourceMail(String to,String subject,String content,String rscPath,String rscId);

}
//创建实现类实现4中方法
package com.mgetwd.jspdemo.sendservice;

@Component
@Slf4j
public class SendService implements SendMailService {
@Autowired
private JavaMailSender mailSender;
@Value("${spring.mail.username}")
private String from;

@Override
public void sendSimpleMail(String to, String centent, String subject) {
    SimpleMailMessage message = new SimpleMailMessage();
    message.setFrom(from);
    message.setTo(to);
    message.setText(centent);
    message.setSubject(subject);
    try {
        mailSender.send(message);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

@Override
public void sendHtmlMail(String to, String subject, String content) {
    MimeMessage message = mailSender.createMimeMessage();
    try {
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
        helper.setFrom(from);
        helper.setSubject(subject);
        helper.setTo(to);
        helper.setText(content,true);
        helper.setCc("xxxxxx @qq.com");
        mailSender.send(message);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

@Override
public void sendAttachmentMail(String to, String subject, String content, String filePath) {
    MimeMessage message = mailSender.createMimeMessage();
    try {
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
        helper.setFrom(from);
        helper.setTo(to);
        helper.setSubject(subject);
        helper.setText(content);
        helper.setCc("xxxxxx @qq.com");//抄送
        FileSystemResource file = new FileSystemResource(new File(filePath));
        String fileName = file.getFilename();
        helper.addAttachment(fileName, file);
        mailSender.send(message);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

@Override
public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) {
    MimeMessage message = mailSender.createMimeMessage();
    try {
    MimeMessageHelper helper=new MimeMessageHelper(message,true);
    helper.setFrom(from);
    helper.setTo(to);
    helper.setSubject(subject);
    helper.setText(content);
    helper.setCc("xxxxxx @qq.com");
    FileSystemResource file=new FileSystemResource(new File(rscPath));
    helper.addInline(rscId,file);
    mailSender.send(message);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

}
//编写测试类
package com.mgetwd.jspdemo.test;

@RunWith(SpringRunner.class)
@SpringBootTest
public class SenMailTest {
@Autowired
private SendService sendService;

@Autowired
private TemplateEngine templateEngine;

@Test
public void testSimpleMail() throws Exception {
    sendService.sendSimpleMail("xxxxxx @qq.com", "从此随心所欲地老去", "我仅仅是用来测试的");
}

@Test
public void testHtmlMail() throws Exception {
    String content = "<html > \n" +
            "<head >\n" +
            "<title > 网页恶搞程序，关不掉的弹出框</title >\n" +
            "</head >" +
            "<body >" +
            "<input type = button value = \"点我之前要有心理准备哦，我是永远也不关不完的对话框！\" onClick = \"var e=1;while(1==1){alert('烈火网提示：这个对话框是关不掉的！')}\" >\n" +
            " 关掉窗口的方法：按下ctrl + alt + del打开任务管理器，结束浏览器进程！\n" +
            "</body >\n" +
            "</html >\n" +
            " <div style = \"text-align:center;margin:30px 0 0 0;\" >" +
            "<hr style = \"color:#999;height:1px;\" > " +
            "如不能显示效果，\n 请按Ctrl + F5刷新本页，更多网页代码：" +
            "<a href = 'http://www.veryhuo.com/' target = '_blank' > " +
            "http://www.baidu.com/</a></div>";
    sendService.sendHtmlMail("xxxxxx @qq.com", "这是一个html页面", content);
}

@Test
public void testsendInlineResourceMail() {
    String filePath = "E:\\start\\测试的.doc";
    sendService.sendAttachmentMail("xxxxxx @qq.com", "请看附件内容", "有附件,请查收", filePath);
}
@Test
public void sendInlineResourceMail() {
    String rscId = "neo006";
    String content="<html><body>这是有图片的邮件：<img src=\'cid:" + rscId + "\' ></body></html>";
    String imgPath = "C:\\bqs\\分期还打包目录\\test\\login-bg.jpg";
    sendService.sendInlineResourceMail("1132879189@qq.com", "主题：这是有图片的邮件", content, imgPath, rscId);
}

}
要想实现发送邮件还需要在qq邮箱上面
! 在这里插入图片描述

之后是配置文件
spring.mail.host=smtp.qq.com
spring.mail.username=2xxxxxxx@qq.com
spring.mail.password=aoierfnzcfjwdbge
#密码是生成的授权码
spring.mail.default-encoding=UTF-8
spring.application.name=spirng-boot-mail
