这里没用最新版，从后面回来了，复制依赖到pom 文件

记得刷一下

修改配置文件

spring.mail.host=smtp.sina.com
    spring.mail.port=465
    spring.mail.username=dingdaydayup@sina.com
    spring.mail.password=nowcoder123
    spring.mail.protocol=smtps
    spring.mail.properties.mail.smtp.ssl.enable=true

使用 JavaMailSender 发送邮件

package com.nowcoder.community.util;
    
    import org.slf4j.Logger;
    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;
    
    /**
     * @Projectname: community
     * @Classname: MailClient
     * @Author: Ding Jiaxiong
     * @Date:2023/4/17 18:53
     */
    
    @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 mimeMessage = mailSender.createMimeMessage();
                MimeMessageHelper helper = new MimeMessageHelper(mimeMessage);
                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());
            }
    
        }
    
    }

来个测试类，测试一下

package com.nowcoder.community;
    
    import com.nowcoder.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;
    
    /**
     * @Projectname: community
     * @Classname: MailTest
     * @Author: Ding Jiaxiong
     * @Date:2023/4/17 19:01
     */
    
    @SpringBootTest
    @RunWith(SpringRunner.class)
    @ContextConfiguration(classes = CommunityApplication.class)
    public class MailTest {
        
    
        @Autowired
        private MailClient mailClient;
    
        @Test
        public void testTextMail() {
        
            mailClient.sendMail("dingjiaxiong@qq.com", "Test", "发送邮件测试~");
        }
    
    }

运行结果

没问题，接收到了

【使用 Thymeleaf 发送 HTML 邮件】

<!DOCTYPE html>
    <html lang="en" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8">
        <title>邮件示例</title>
    </head>
    <body>
    
    <p>欢迎你, <span style="color: red"th:text="${username}"></span>!</p>
    
    </body>
    </html>

做一个模板出来

![在这里插入图片描述][d641ea0cbf654bbfaddae9b641ca4c31.png_pic_center]

编写测试方法

@Autowired
        private TemplateEngine templateEngine;
    
        @Test
        public void testHtmlMail() {
        
            Context context = new Context();
            context.setVariable("username", "dingjiaxiong");
    
            String content = templateEngine.process("/mail/demo", context);
            System.out.println(content);
    
            mailClient.sendMail("dingjiaxiong@qq.com", "HTML", content);
        }

运行结果
