更新時間：2017年04月18日 16:34:50 作者：偶遇晨光

本篇文章主要介紹了springMVC發(fā)送郵件的簡單實(shí)現(xiàn) ，主要是利用利用javax.mail發(fā)送郵件，圖片與附件都可發(fā)送，有興趣的可以了解一下

利用javax.mail發(fā)送郵件，圖片與附件都可發(fā)送

1，Controller類

package com.web.controller.api;

import javax.annotation.Resource;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.service.EmailService;

@Controller
@RequestMapping("api")
public class EmailTaskController {

  private static final Logger logger = LoggerFactory.getLogger(EmailTaskController.class);

  @Resource 
  EmailService emailService;
  
  @RequestMapping("sendEmailTask")
  public void sendEmailTask() {
    logger.info("-------------執(zhí)行發(fā)送郵件START---------------");
      //寫入excel
      //insuranceService.excelManage();
      //發(fā)郵件
      emailService.emailManage();
    
    logger.info("-------------執(zhí)行發(fā)送郵件END---------------");
    
  }

}

2,service類

package com.service.impl;

import java.io.File;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

import javax.annotation.Resource;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.apache.log4j.Logger;
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 com.entity.MailModel;
import com.service.EmailService;
import com.SimpleException;

@Service
public class EmailServiceImpl implements EmailService {
  private static Logger logger = Logger.getLogger(EmailServiceImpl.class);

  private String excelPath = "d://";
  
  @Resource
  private JavaMailSender javaMailSender;
  
  @Resource
  private SimpleMailMessage simpleMailMessage;
  
  @Override
  public void emailManage(){
    MailModel mail = new MailModel();
    //主題
    mail.setSubject("清單"); 
    
    //附件
    Map<String, String> attachments = new HashMap<String, String>();
    attachments.put("清單.xlsx",excelPath+"清單.xlsx");
    mail.setAttachments(attachments);
    
    //內(nèi)容
    StringBuilder builder = new StringBuilder();
    builder.append("<html><body>你好！<br />");
    builder.append("&nbsp&nbsp&nbsp&nbsp附件是個人清單。<br />");
    builder.append("&nbsp&nbsp&nbsp&nbsp其中人信息；<br />");
    builder.append("</body></html>");
    String content = builder.toString();
    
    mail.setContent(content);
    
    sendEmail(mail);
  }

MailModel實(shí)體類

  private String[] attachFileNames;//附件
