## 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")
     @ResponseBody
     public 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 {
    
    
     @Autowired
     private EmailConfig emailConfig;
     
     @Autowired
     private JavaMailSender mailSender;
     
     @Override
     public 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
     @Override
     public 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);
     }
    
    }
