1.文件组织结构
2.建立Maven项目，写pom文件

3.邮件服务接口
package com.player.service;
public interface MailService {
/**
* 发送普通文本
* @param to
* @param subject
* @param content
*/
public void sendSimpleMail(String to, String subject, String content);
/**
* 发送 html 代码的邮件
* @param to
* @param subject
* @param content
*/
public void sendHtmlMail(String to, String subject, String content);
/**
* 发送附件的邮件
* @param to
* @param subject
* @param content
* @param filePath
*/
public void sendAttachmentsMail(String to, String subject, String content, String filePath);
/**
* 发送内嵌的文件
* @param to
* @param subject
* @param content
* @param rscPath
* @param rscId
*/
public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId);
}
4.邮件服务实现
package com.player.service.impl;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;
import com.player.service.MailService;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;
@Component
public class MailServiceImpl implements MailService{
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private JavaMailSender mailSender;
@Value("${fromMail}")
private String from;
/**
* 发送文本邮件
* @param to
* @param subject
* @param content
*/
@Override
public void sendSimpleMail(String to, String subject, String content) {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(content);
try {
mailSender.send(message);
logger.info("简单邮件已经发送。");
} catch (Exception e) {
logger.error("发送简单邮件时发生异常！", e);
}
}
/**
* 发送html邮件
* @param to
* @param subject
* @param content
*/
@Override
public void sendHtmlMail(String to, String subject, String content) {
MimeMessage message = mailSender.createMimeMessage();
try {
//true表示需要创建一个multipart message
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
mailSender.send(message);
logger.info("html邮件发送成功");
} catch (MessagingException e) {
logger.error("发送html邮件时发生异常！", e);
}
}
/**
* 发送带附件的邮件
* @param to
* @param subject
* @param content
* @param filePath
*/
public void sendAttachmentsMail(String to, String subject, String content, String filePath){
MimeMessage message = mailSender.createMimeMessage();
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));
String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
helper.addAttachment(fileName, file);
mailSender.send(message);
logger.info("带附件的邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送带附件的邮件时发生异常！", e);
}
}
/**
* 发送正文中有静态资源（图片）的邮件
* @param to
* @param subject
* @param content
* @param rscPath
* @param rscId
*/
public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId){
MimeMessage message = mailSender.createMimeMessage();
try {
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
System.out.println("content="+content);
System.out.println("rscId="+rscId);
System.out.println("rscPath="+rscPath);
FileSystemResource res = new FileSystemResource(new File(rscPath));
helper.addInline(rscId, res);
mailSender.send(message);
logger.info("嵌入静态资源的邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送嵌入静态资源的邮件时发生异常！", e);
}
}
}
5.全局配置application.properties
前排提示：password并不是你的密码，而是授权码，拿网易举例：
server.port=8080
spring.application.name=spirngboot-mail
spring.mail.host=smtp.163.com
spring.mail.username=edw358@163.com
spring.mail.password=EHIDCDQIWAHYQFGT
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.default-encoding=UTF-8
spring.mail.port=465
spring.mail.properties.mail.smtp.socketFactory.port = 465
spring.mail.properties.mail.smtp.socketFactory.class = javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback = false
fromMail=edw358@163.com
#log
logging.file=E:\\logs\\mail_log.log
6.MailController
package com.player.controller;
import com.player.service.MailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class MailController {
@Autowired
MailService mailService;
@PostMapping(value = "/sendSimpleMail")
public String sendSimpleMail(String to, String subject, String content){
mailService.sendSimpleMail(to, subject, content);
return "发送成功";
}
@PostMapping(value = "/sendHtmlMail")
public String sendHtmlMail(String to, String subject, String content){
mailService.sendHtmlMail(to, subject, content);
return "发送成功";
}
@PostMapping(value = "/sendAttachmentMail")
public String sendAttachmentsMail(String to, String subject, String content, String filePath){
mailService.sendAttachmentsMail(to, subject, content, filePath);
return "发送成功";
}
@PostMapping(value = "/sendInlineResourceMail")
public String sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId){
mailService.sendInlineResourceMail(to, subject, content, rscPath, rscId);
return "发送成功";
}
}
7.运行
