接口代码
package com.qiankai.qqlogin.util.sendmail; /** * 发送邮件接口 * * @author kai_qian * @version v1.0 * @since 2020/02/25 11:32 */ public interface IMailService { /** * 发送文本邮件 * @param to 收件人 * @param subject 主题 * @param content 内容 */ void sendSimpleMail(String to, String subject, String content); /** * 发送HTML邮件 * @param to 收件人 * @param subject 主题 * @param content 内容 */ void sendHtmlMail(String to, String subject, String content); /** * 发送带附件的邮件 * @param to 收件人 * @param subject 主题 * @param content 内容 * @param filePath 附件 */ void sendAttachmentsMail(String to, String subject, String content, String filePath); }

业务实现代码
package com.qiankai.qqlogin.util.sendmail; 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.core.io.FileSystemResource; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import java.io.File; /** * 发送邮件的实现类 * * @author kai_qian * @version v1.0 * @since 2020/02/25 11:32 */ @Service public class IMailServiceImpl implements IMailService { private final Logger logger = LoggerFactory.getLogger(this.getClass()); @Autowired private JavaMailSender mailSender; /** * 我的QQ邮箱 */ @Value("${spring.mail.from}") private String from; @Override public void sendSimpleMail(String to, String subject, String content) { //创建SimpleMailMessage对象 SimpleMailMessage message = new SimpleMailMessage(); //邮件发送人 message.setFrom(from); //邮件接收人 message.setTo(to); //邮件主题 message.setSubject(subject); //邮件内容 message.setText(content); //发送邮件 mailSender.send(message); } @Override public void sendHtmlMail(String to, String subject, String content) { //获取MimeMessage对象 MimeMessage message = mailSender.createMimeMessage(); MimeMessageHelper messageHelper; try { messageHelper = new MimeMessageHelper(message, true); //邮件发送人 messageHelper.setFrom(from); //邮件接收人 messageHelper.setTo(subject); //邮件主题 message.setSubject(subject); //邮件内容,html格式 messageHelper.setText(content, true); //发送 mailSender.send(message); //日志信息 logger.info("邮件已经发送。"); } catch (MessagingException e) { logger.error("发送邮件时发生异常!", e); } } @Override public void sendAttachmentsMail(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, true); FileSystemResource file = new FileSystemResource(new File(filePath)); String fileName = filePath.substring(filePath.lastIndexOf(File.separator)); helper.addAttachment(fileName, file); mailSender.send(message); //日志信息 logger.info("邮件已经发送。"); } catch (MessagingException e) { logger.error("发送邮件时发生异常!", e); } } }

直接调用方法即可
@RestController
-
@RequestMapping("/mail")
public class EmailController {
/** 邮件接收者 */
private static final String TEST_RECEIVER = "xxxxxxx@qq.com";
@Autowired
private IMailService mailService;
@GetMapping("/simple")
public String sendSimpleMail() {
mailService.sendSimpleMail(TEST_RECEIVER, "你好,普通邮件","内容:第一封邮件");
return "simple-ok";
}
@GetMapping("/html")
public String sendHTMLMail() {
mailService.sendSimpleMail(TEST_RECEIVER,"主题:你好html邮件","<h1>内容:</h1><p>第一封html邮件<p>");
return "html-ok";
}
}
```
