这篇文章给大家分享的是有关基于SpringBoot如何实现发送带附件的邮件的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
<!--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
