如何在Spring boot中配置和发送邮件呢，今天我们就以QQ邮件为例，给大家说一下在spring Boot中发送，包括简单邮件，html格式邮件，包含附件的邮件，和发送图片内容的邮件
spring boot配置邮件
1.配置邮件
1.1配置maven依赖
1.2在application.properties中配置发送邮件的用户名 密码等信息
1.3配置QQ邮箱的IMAP/SMTP信息，来配置spring.mail.password的信息
1.3.1登录QQ邮箱，打开设置
1.3.2 点击设置后，点击账号，找到以下模块，点击开启，就可以生成授权码
1.4编写Service
package com.team.base.service;
import lombok.extern.java.Log;
import lombok.extern.log4j.Log4j;
import lombok.extern.slf4j.Slf4j;
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.Service;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;
/**
* @com.team.base.service
* @fenghaiju
* @2018/3/19-16:46
* @springBootBase
**/
@Service
@Slf4j
public class MailService {
@Autowired
private JavaMailSender sender;
@Value("${spring.mail.username}")
private String from;
/**
* 发送纯文本的简单邮件
* @param to
* @param subject
* @param content
*/
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 {
sender.send(message);
log.info(" 简单邮件已经发送。");
} catch (Exception e) {
log.error(" 发送简单邮件时发生异常！",e);
}
}
/**
* 发送html格式的邮件
* @param to
* @param subject
* @param content
*/
public void sendHtmlMail(String to, String subject, String content){
MimeMessage message = sender.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);
sender.send(message);
log.info("html 邮件已经发送。");
} catch (MessagingException e) {
log.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 = sender.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);
FileSystemResource file = new FileSystemResource(new File(filePath));
String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
helper.addAttachment(fileName, file);
sender.send(message);
log.info(" 带附件的邮件已经发送。");
} catch (MessagingException e) {
log.error(" 发送带附件的邮件时发生异常！",e);
}
}
/**
* 发送嵌入静态资源（一般是图片）的邮件
* @param to
* @param subject
* @param content 邮件内容，需要包括一个静态资源的id，比如：<img src=\"cid:rscId01\" >
* @param rscPath 静态资源路径和文件名
* @param rscId 静态资源id
*/
public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId){
MimeMessage message = sender.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);
FileSystemResource res = new FileSystemResource(new File(rscPath));
helper.addInline(rscId, res);
sender.send(message);
log.info(" 嵌入静态资源的邮件已经发送。");
} catch (MessagingException e) {
log.error(" 发送嵌入静态资源的邮件时发生异常！",e);
}
}
}
1.5编写Controller
package com.team.base.controller;
import com.team.base.service.MailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @com.team.base.controller
* @fenghaiju
* @2018/3/19-16:51
* @springBootBase
**/
@RestController
@RequestMapping("/mail")
public class MailController {
@Autowired
private MailService mailService;
/**
* 简单发送
* @return
*/
@RequestMapping("/sendSimpleMail")
public ResponseEntity<?> sendSimpleMail(){
mailService.sendSimpleMail("fenghaiju@sohu.com", "简单邮件", "简单的邮件测试");
return ResponseEntity.ok(true);
}
/**
* 发送html内容
* @return
*/
@RequestMapping("/sendHtmlMail")
public ResponseEntity<?> sendHtmlMail(){
mailService.sendHtmlMail("fenghaiju@sohu.com", "html邮件", "<html><body><h3>你好， 这是一封模板邮件!</h3></body></html>");
return ResponseEntity.ok(true);
}
/**
* 发送附件
* @return
*/
@RequestMapping("/sendAttachmentsMail")
public ResponseEntity<?> sendAttachmentsMail(){
mailService.sendAttachmentsMail("fenghaiju@sohu.com", "附件邮件", "测试邮件内容","D:\\article\\结尾.txt");
return ResponseEntity.ok(true);
}
/**
* 发送图片
* @return
*/
@RequestMapping("/sendInlineResourceMail")
public ResponseEntity<?> sendInlineResourceMail(){
mailService.sendInlineResourceMail("fenghaiju@sohu.com", "发送图片", "<img src=\"cid:rscId01\" >","D:\\article\\架构师.png","rscId01");
return ResponseEntity.ok(true);
}
}
1.6测试邮件
1.6.1测试简单邮件
1.6.2 测试Html格式邮件
1.6.3 测试附件邮件
1.6.4 测试图片邮件
