本文内容纲要：
**springMVC发送邮件**
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;
importcom.entity.MailModel;
publicinterfaceEmailService{
/**
*email配置
*@return
*/
publicbooleanemailManage();
/**
*发送邮件
*@parammail
*/
publicbooleansendEmail(MailModelmail);
}
packagecom.service.impl;
importjava.io.File;

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

@Override
publicvoidemailManage(){
MailModelmail=newMailModel();
//主题
mail.setSubject("清单");
//附件
Map<String,String>attachments=newHashMap<String,String>();
attachments.put("清单.xlsx",excelPath+"清单.xlsx");
mail.setAttachments(attachments);
//内容
StringBuilderbuilder=newStringBuilder();
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>");
Stringcontent=builder.toString();
mail.setContent(content);
sendEmail(mail);
}
/**

@Override

MailModel实体类
packagecom.support.entity;
importjava.util.Map;
publicclassMailModel{

/**

*/

/**
*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
*/
privateMap<String,String>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
*/
privateMap<String,String>attachments;
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(){
