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

<!--发送email依赖--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>

service

package com.ykmimi.job.service;import org.springframework.stereotype.Service;import java.util.Map;@Servicepublic interface MailService { /** * TODO 发送带附件的邮件 , 需要进行重载方法 */ Map<String, Object> sendAttachmentsMail(String to, String subject, String content, String filePath);}

service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;@Servicepublic 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<String, Object> sendAttachmentsMail(String to, String subject, String content, String filePath) { System.out.println("in sendAttachmentsMail"); System.out.println(filePath); MimeMessage message = mailSender.createMimeMessage(); Map<String, Object> 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=10MBspring.servlet.multipart.max-request-size=10MB##发送email设置spring.application.name=spring-boot-mailspring.mail.host=smtp.126.comspring.mail.username=hostinbj@126.comspring.mail.password=1314520jyspring.mail.default-encoding=UTF-8##邮件主机地址mail.fromMail.addr=hostinbj@126.comspring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory#邮件端口spring.mail.properties.mail.smtp.socketFactory.port=465spring.mail.properties.mail.smtp.auth=truespring.mail.properties.mail.smtp.starttls.enable=truespring.mail.properties.mail.smtp.starttls.required=true

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
