springMVC发送邮件的简单实现

springMVC发送邮件的简单实现

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 attachments = new HashMap();

attachments.put("清单.xlsx",excelPath+"清单.xlsx");

mail.setAttachments(attachments);

//内容

StringBuilder builder = new StringBuilder();

builder.append("

builder.append("&nbsp&nbsp&nbsp&nbsp附件是个人清单。
");

builder.append("&nbsp&nbsp&nbsp&nbsp其中人信息；
");

builder.append("");

String content = builder.toString();

mail.setContent(content);

sendEmail(mail);

}

/**

*/

@Override

public void sendEmail(MailModel mail) {

// 建立邮件消息

MimeMessage message = javaMailSender.createMimeMessage();

MimeMessageHelper messageHelper;

try {

messageqGLpGKwAHelper = new MimeMessageHelper(message, true, "UTF-8");

// 设置发件人邮箱

if (mail.getEmailFrom()!=null) {

messageHelper.setFrom(mail.getEmailFrom());

} else {

messageHelper.setFrom(simpleMailMessage.getFrom());

}

// 设置收件人邮箱

if (mail.getToEmails()!=null) {

String[] toEmailArray = mail.getToEmails().split(";");

List toEmailList = new ArrayList();

if (null == toEmailArray || toEmailArray.length <= 0) {

throw new SimpleException("收件人邮箱不得为空！");

} else {

for (String s : toEmailArray) {

if (s!=null&&!s.equals("")) {

toEmailList.add(s);

}

}

if (null == toEmailList || toEmailList.size() <= 0) {

throw new SimpleException("收件人邮箱不得为空！");

} else {

toEmailArray = new String[toEmailList.size()];

for (int i = 0; i < toEmailList.size(); i++) {

toEmailArray[i] = toEmailList.get(i);

}

}

}

messageHelper.setTo(toEmailArray);

} else {

messageHelper.setTo(simpleMailMessage.getTo());

}

// 邮件主题

if (mail.getSubject()!=null) {

messageHelper.setSubject(mail.getSubject());

} else {

messageHelper.setSubject(simpleMailMessage.getSubject());

}

// true 表示启动HTML格式的邮件

messageHelper.setText(mail.getContent(), true);

// 添加图片

if (null != mail.getPictures()) {

for (Iterator> it = mail.getPictures().entrySet()

.iterator(); it.hasNext();) {

Map.Entry entry = it.next();

String cid = entry.getKey();

String filePath = entry.getValue();

if (null == cid || null == filePath) {

throw new RuntimeException("请确认每张图片的ID和图片地址是否齐全！");

}

File file = new File(filePath);

if (!file.exists()) {

throw new RuntimeException("图片" + filePath + "不存在！");

}

FileSystemResource img = new FileSystemResource(file);

messageHelper.addInline(cid, img);

}

}

// 添加附件

if (null != mail.getAttachments()) {

for (Iterator> it = mail.getAttachments()

.entrySet().iterator(); it.hasNext();) {

Map.Entry entry = it.next();

String cid = entry.getKey();

String filePath = entry.getValue();

if (null == cid || null == filePath) {

throw new RuntimeException("请确认每个附件的ID和地址是否齐全！");

}

File file = new File(filePath);

if (!file.exists()) {

throw new RuntimeException("附件" + filePath + "不存在！");

}

FileSystemResource fileResource = new FileSystemResource(file);

messageHelper.addAttachment(cid, fileResource);

}

}

messageHelper.setSentDate(new Date());

// 发送邮件

javaMailSender.send(message);

logger.info("------------发送邮件完成----------");

} catch (MessagingException e) {

e.printStackTrace();

}

}

}

MailModel实体类

package com.support.entity;

import java.util.Map;

public class MailModel {

/**

* 发件人邮箱服务器

*/

private String emailHost;

/**

* 发件人邮箱

*/

private String emailFrom;

/**

* 发件人用户名

*/

private String emailUserName;

/**

* 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 pictures;

/**

* 邮件中的附件，为空时无附件。map中的key为附件ID，value为附件地址

*/

private Map 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() {

return fromAddress;

}

public void setFromAddress(String fromAddress) {

this.fromAddress = fromAddress;

}

public String getToAddresses() {

return toAddresses;

}

public void setToAddresses(String toAddresses) {

this.toAddresses = toAddresses;

}

public String getSubject() {

return subject;

}

public void setSubject(String subject) {

this.subject = subject;

}

public String getContent() {

return content;

}

public void setContent(String content) {

this.content = content;

}

public String[] getAttachFileNames() {

return attachFileNames;

}

public void setAttachFileNames(String[] attachFileNames) {

this.attachFileNames = attachFileNames;

}

public String getEmailHost() {

return emailHost;

}

public void setEmailHost(String emailHost) {

this.emailHost = emailHost;

}

public String getEmailFrom() {

return emailFrom;

}

public void setEmailFrom(String emailFrom) {

this.emailFrom = emailFrom;

}

public String getEmailUserName() {

return emailUserName;

}

public void setEmailUserName(String emailUserName) {

this.emailUserName = emailUserName;

}

public String getEmailPassword() {

return emailPassword;

}

public void setEmailPassword(String emailPassword) {

this.emailPassword = emailPassword;

}

public String getToEmails() {

return toEmails;

}

public void setToEmails(String toEmails) {

this.toEmails = toEmails;

}

public Map getPictures() {

return pictures;

}

public void setPictures(Map pictures) {

this.pictures = pictures;

}

public Map getAttachments() {

return attachments;

}

}

spring.xml添加配置信息
