springMVC发送邮件的简单实现

2019年07月22日 | 移动技术网IT编程 | 我要评论

利用javax.mail发送邮件，图片与附件都可发送

1，controller类

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("-------------执行发送邮件start---------------");
      //写入excel
      //insuranceservice.excelmanage();
      //发邮件
      emailservice.emailmanage();
    
    logger.info("-------------执行发送邮件end---------------");
    
  }

}

2,service类

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();
    //主题
    mail.setsubject("清单"); 
    
    //附件
    map<string, string> attachments = new hashmap<string, string>();
    attachments.put("清单.xlsx",excelpath+"清单.xlsx");
    mail.setattachments(attachments);
    
    //内容
    stringbuilder builder = new stringbuilder();
    builder.append("<html><body>你好！<br />");
    builder.append("    附件是个人清单。<br />");
    builder.append("    其中人信息；<br />");
    builder.append("</body></html>");
    string content = builder.tostring();
    
    mail.setcontent(content);
    
    sendemail(mail);
  }

mailmodel实体类

package com.support.entity;

   */

  /**
   * 发件人密码
   */
  private string emailpassword;

  /**
   * 收件人邮箱，多个邮箱以“;”分隔
   */
  private string toemails;
  /**
   * 邮件主题
   */
  private string subject;
  /**
   * 邮件内容
   */
  private string content;
  /**
   * 邮件中的图片，为空时无图片。map中的key为图片id，value为图片地址

   */
  private map<string, string> attachments;
  
  
  private string fromaddress;//发送人地址1个
  
  private string toaddresses;//接收人地址,可以为很多个，每个地址之间用";"分隔，比方说450065208@qq.com;lpf@sina.com
  
  private string[] attachfilenames;//附件 

  public string getfromaddress() {

spring.xml添加配置信息

dev.properties配置
