基于SpringBoot实现发送带附件的邮件

基于SpringBoot实现发送带附件的邮件

这篇文章主要介绍了基于SpringBoot实现发送带附件的邮件,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

org.springframework.boot

spring-boot-starter-mail

service

package com.ykmimi.job.service;

import org.springframework.stereotype.Service;

import java.util.Map;

@Service

public interface MailService {

/**

* TODO 发送带附件的邮件 , 需要进行重载方法

*/

Map sendAttachmentsMail(String to, String subject, String content, String filePath);

}

servictRyvmdRme实现

package com.ykmimi.job.service.impl;

import com.ykmimi.job.service.MailService;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.mail.javamail.JavaMailSender;

import org.springframework.mail.javamail.MimeMessageHelper;

import org.springframework.stereotype.Service;

import org.springframework.util.ResourceUtils;

import javax.annotation.Resource;

import javax.mail.MessagingException;

import javax.mail.internet.MimeMessage;

import java.io.File;

import java.io.FileNotFoundException;

import java.util.HashMap;

import java.util.Map;

@Service

public class MailServiceImpl implements MailService {

@Resource

private JavaMailSender mailSender;

//发送者

@Value("${mail.fromMail.addr}")

private String from;

//TODO 设置发送邮件重载方式

@Override

public Map sendAttachmentsMail(String to, String subject, String content, String filePath) {

System.out.println("in sendAttachmentsMail");

System.out.println(filePath);

MimeMessage message = mailSender.createMimeMessage();

Map map = new HashMap<>();

try {

MimeMessageHelper helper = new MimeMessageHelper(message, true);

helper.setFrom(from);

helper.setTo(to);

helper.setSubject(subject);

helper.setText(content, true);

// FileSystemResource file = new FileSystemResource(new File(filePath));

// 发送附件

File file = new File(filePath);

file = ResourceUtils.getFile(file.getAbsolutePath());

String fileName = filePath.substring(filePath.lastIndexOf(File.separator));

// String fileName = filePath.substring(filePath.lastIndexOf("/"));

// String fileName = "附件";

System.out.println(fileName);

//添加多个附件可以使用多条 helper.addAttachment(fileName,file);

//helper.addAttachment(fileName,file);

helper.addAttachment(fileName, file);

mailSender.send(message);

map.put("code", 1);

map.put("message", "发送成功");

return map;

} catch (MessagingException e) {

e.printStackTrace();

map.put("code",0);

map.put("message","发送失败");

return map;

} catch (FileNotFoundException e) {

e.printStackTrace();

map.put("code",-1);

map.put("message","没有文件");

return map;

} finally {

}

}

}

或将邮件内容及邮件地址等封装为EmailContent的bean实体

通过Controll而接受.

下面是我的邮件主机配置,大家可以拿去用

##上传文件限制大小

spring.servlet.multipart.max-file-size=10MB

spring.servlet.multipart.max-request-size=10MB

##发送email设置

spring.application.name=spring-boot-mail

spring.mail.host=smtp.126.com

spring.mail.username=hostinbj@126.com

spring.mail.password=1314520jy

spring.mail.default-encoding=UTF-8

##邮件主机地址

mail.fromMail.addr=hostinbj@126.com

spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

#邮件端口

spring.mail.properties.mail.smtp.socketFactory.port=465

spring.mail.properties.mail.smtp.auth=true

spring.mail.properties.mail.smtp.starttls.enable=true

spring.mail.properties.mail.smtp.starttls.required=true
