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;
@Service
public 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;
@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<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=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
