利用javax.mail发送邮件，图片与附件都可发送

1，Controller类

packagecom.web.controller.api;

importjavax.annotation.Resource;

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

importcom.service.EmailService;

@Controller
@RequestMapping("api")
publicclassEmailTaskController{

privatestaticfinalLoggerlogger=LoggerFactory.getLogger(EmailTaskController.class);

@Resource
EmailServiceemailService;

@RequestMapping("sendEmailTask")
publicvoidsendEmailTask(){
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

packagecom.service.impl;

importjava.io.File;
importjava.util.ArrayList;
importjava.util.Date;
importjava.util.HashMap;
importjava.util.Iterator;
importjava.util.List;
importjava.util.Map;

importjavax.annotation.Resource;
importjavax.mail.MessagingException;
importjavax.mail.internet.MimeMessage;

importorg.apache.log4j.Logger;
importorg.springframework.beans.factory.annotation.Value;
importorg.springframework.core.io.FileSystemResource;
importorg.springframework.mail.SimpleMailMessage;
importorg.springframework.mail.javamail.JavaMailSender;
importorg.springframework.mail.javamail.MimeMessageHelper;
importorg.springframework.stereotype.Service;

importcom.entity.MailModel;
importcom.service.EmailService;
importcom.SimpleException;

@Service
publicclassEmailServiceImplimplementsEmailService{
privatestaticLoggerlogger=Logger.getLogger(EmailServiceImpl.class);

privateStringexcelPath="d://";

@Resource
privateJavaMailSenderjavaMailSender;

@Resource
privateSimpleMailMessagesimpleMailMessage;

@Override
publicvoidemailManage(){
MailModelmail=newMailModel();
//主题
mail.setSubject("清单");

//附件
Mapattachments=newHashMap();
attachments.put("清单.xlsx",excelPath+"清单.xlsx");
mail.setAttachments(attachments);

//内容
StringBuilderbuilder=newStringBuilder();
builder.append("你好！
");
builder.append("    附件是个人清单。
");
builder.append("    其中人信息；
");
builder.append("");
Stringcontent=builder.toString();

mail.setContent(content);

sendEmail(mail);
}



/**
*发送邮件

*@authorchenyq
*@date2016-5-9上午11:18:21
*@throwsException
*/
@Override
publicvoidsendEmail(MailModelmail){
//建立邮件消息
MimeMessagemessage=javaMailSender.createMimeMessage();

MimeMessageHelpermessageHelper;
try{
messageHelper=newMimeMessageHelper(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(";");
ListtoEmailList=newArrayList();
if(null==toEmailArray||toEmailArray.length<=0){
thrownewSimpleException("收件人邮箱不得为空！");
}else{
for(Strings:toEmailArray){
if(s!=null&&!s.equals("")){
toEmailList.add(s);
}
}
if(null==toEmailList||toEmailList.size()<=0){
thrownewSimpleException("收件人邮箱不得为空！");
}else{
toEmailArray=newString[toEmailList.size()];
for(inti=0;i>it=mail.getPictures().entrySet()
.iterator();it.hasNext();){
Map.Entryentry=it.next();
Stringcid=entry.getKey();
StringfilePath=entry.getValue();
if(null==cid||null==filePath){
thrownewRuntimeException("请确认每张图片的ID和图片地址是否齐全！");
}

Filefile=newFile(filePath);
if(!file.exists()){
thrownewRuntimeException("图片"+filePath+"不存在！");
}

FileSystemResourceimg=newFileSystemResource(file);
messageHelper.addInline(cid,img);
}
}

//添加附件
if(null!=mail.getAttachments()){
for(Iterator>it=mail.getAttachments()
.entrySet().iterator();it.hasNext();){
Map.Entryentry=it.next();
Stringcid=entry.getKey();
StringfilePath=entry.getValue();
if(null==cid||null==filePath){
thrownewRuntimeException("请确认每个附件的ID和地址是否齐全！");
}

Filefile=newFile(filePath);
if(!file.exists()){
thrownewRuntimeException("附件"+filePath+"不存在！");
}

FileSystemResourcefileResource=newFileSystemResource(file);
messageHelper.addAttachment(cid,fileResource);
}
}
messageHelper.setSentDate(newDate());
//发送邮件
javaMailSender.send(message);
logger.info("------------发送邮件完成----------");

}catch(MessagingExceptione){

e.printStackTrace();
}
}

}

MailModel实体类

packagecom.support.entity;

importjava.util.Map;

publicclassMailModel{

/**
*发件人邮箱服务器
*/
privateStringemailHost;
/**
*发件人邮箱
*/
privateStringemailFrom;

/**
*发件人用户名
*/
privateStringemailUserName;

/**
*发件人密码
*/
privateStringemailPassword;

/**
*收件人邮箱，多个邮箱以“;”分隔
*/
privateStringtoEmails;
/**
*邮件主题
*/
privateStringsubject;
/**
*邮件内容
*/
privateStringcontent;
/**
*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
*/
privateMappictures;
/**
*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
*/
privateMapattachments;


privateStringfromAddress;//发送人地址1个

privateStringtoAddresses;//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

privateString[]attachFileNames;//附件

publicStringgetFromAddress(){
returnfromAddress;
}

publicvoidsetFromAddress(StringfromAddress){
this.fromAddress=fromAddress;
}

publicStringgetToAddresses(){
returntoAddresses;
}

publicvoidsetToAddresses(StringtoAddresses){
this.toAddresses=toAddresses;
}

publicStringgetSubject(){
returnsubject;
}

publicvoidsetSubject(Stringsubject){
this.subject=subject;
}

publicStringgetContent(){
returncontent;
}

publicvoidsetContent(Stringcontent){
this.content=content;
}

publicString[]getAttachFileNames(){
returnattachFileNames;
}

publicvoidsetAttachFileNames(String[]attachFileNames){
this.attachFileNames=attachFileNames;
}

publicStringgetEmailHost(){
returnemailHost;
}

publicvoidsetEmailHost(StringemailHost){
this.emailHost=emailHost;
}

publicStringgetEmailFrom(){
returnemailFrom;
}

publicvoidsetEmailFrom(StringemailFrom){
this.emailFrom=emailFrom;
}

publicStringgetEmailUserName(){
returnemailUserName;
}

publicvoidsetEmailUserName(StringemailUserName){
this.emailUserName=emailUserName;
}

publicStringgetEmailPassword(){
returnemailPassword;
}

publicvoidsetEmailPassword(StringemailPassword){
this.emailPassword=emailPassword;
}

publicStringgetToEmails(){
returntoEmails;
}

publicvoidsetToEmails(StringtoEmails){
this.toEmails=toEmails;
}

publicMapgetPictures(){
returnpictures;
}

publicvoidsetPictures(Mappictures){
this.pictures=pictures;
}

publicMapgetAttachments(){
returnattachments;
}

publicvoidsetAttachments(Mapattachments){
this.attachments=attachments;
}


}

spring.xml添加配置信息








${mail.host}



true
25000



${mail.username}


${mail.password}


UTF-8

dev.properties配置

#emailconfiguration
mail.host=smtp.163.com
mail.username=chenyanqing5945
mail.password=123456

mail.from=chenyanqing5945@163.com#发件人
mail.to=164792930@qq.com#收件人（多个用,隔开）
mail.subject=testEmail#主题
