实现最简单的带标题以及文本内容的邮件发送：

实现

在上面成功实现发送简单邮件的基础上

发送附件就是添加一个文件

这里在static下添加一个文件

在Controller中新增方法

@RequestMapping("sendAttachmentEmail")@ResponseBodypublic String sendAttachmentEmail() {File file = new File("src/main/resources/static/badao.gif");emailService.sendAttachmentMail("****@qq.com", "测试附件发送", "霸道流氓气质", file);return "success";}

在service中添加方法

package com.example.demo.email;import java.io.File;import org.springframework.stereotype.Service;@Service public interface EmailService {//发送简单邮件void sendSimpleMail(String sendTo,String title,String content);//发送带附件的邮件void sendAttachmentMail(String sendTo,String title,String content,File file); }

在实现类中添加方法

package com.example.demo.email;import java.io.File;import javax.mail.internet.MimeMessage;import org.springframework.beans.factory.annotation.Autowired; 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; @Service public class EmailServiceImpl implements EmailService {@Autowiredprivate EmailConfig emailConfig;@Autowiredprivate JavaMailSender mailSender;@Overridepublic void sendSimpleMail(String sendTo, String title, String content) {//简单邮件的发送SimpleMailMessage message = new SimpleMailMessage();message.setFrom(emailConfig.getEmailFrom());message.setTo(sendTo);message.setSubject(title);message.setText(content);mailSender.send(message);}//发送带附件的邮件@Overridepublic void sendAttachmentMail(String sendTo, String title, String content, File file) {MimeMessage message =mailSender.createMimeMessage();try {MimeMessageHelper helper =new MimeMessageHelper(message,true);helper.setFrom(emailConfig.getEmailFrom());helper.setTo(sendTo);helper.setText(content);FileSystemResource resource = new FileSystemResource(file);helper.addAttachment("附件", resource);} catch (Exception e) {e.printStackTrace();}mailSender.send(message);}}

效果

启动项目，访问
