相信使用过Spring的众多开发者都知道Spring提供了非常好用的JavaMailSender接口实现邮件发送，在Spring Boot的Starter模块中也为此提供了自动化配置。下面通过实例来讲解如何在Spring Boot中使用JavaMailSender发送邮件。
一、引入依赖
org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-mail
二、application.properties配置
##端口号 server.port=8888 ##根据自己的情况填写 ##邮箱服务器地址 ##QQ smtp.qq.com ##sina smtp.sina.cn ##aliyun smtp.aliyun.com ##163 smtp.163.com spring.mail.host=smtp.qq.com ##邮箱用户名 [email protected] ##邮箱密码（注意：QQ邮箱应该使用授权码） spring.mail.password=**************** ##编码格式 spring.mail.default-encoding=UTF-8 ##发送邮件地址 [email protected] ##接收邮件地址 [email protected]
三、邮件发送控制器
package com.xieke.test.demo;
import java.io.File;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
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.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* 邮件发送控制器
*
* @author 邪客
*
*/
@RestController
public class MailController {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Value("${mail.fromMail.sender}")
private String sender;// 发送者
@Value("${mail.fromMail.receiver}")
private String receiver;// 接受者
@Autowired
private JavaMailSender javaMailSender;
/**
* @Description http://localhost:8888/sendMail
* @method 发送文本邮件
* @return
*/
@RequestMapping("/sendMail")
public String sendMail() {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(sender);
message.setTo(receiver);
message.setSubject("邪客发送文本邮件测试");// 标题
message.setText("世界，你好！--->文本邮件");// 内容
try {
javaMailSender.send(message);
logger.info("文本邮件发送成功！");
return "success";
} catch (Exception e) {
logger.error("文本邮件发送异常！", e);
return "failure";
}
}
/**
* @Description http://localhost:8888/sendHtmlMail
* @method 发送html邮件
* @return
*/
@RequestMapping("/sendHtmlMail")
public String testHtmlMail() {
String content = "hello world ! --->Html邮件
";
MimeMessage message = javaMailSender.createMimeMessage();
try {
//true表示需要创建一个multipart message
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(sender);
helper.setTo(receiver);
helper.setSubject("邪客发送Html邮件测试");
helper.setText(content, true);
javaMailSender.send(message);
logger.info("Html邮件发送成功！");
return "success";
} catch (MessagingException e) {
logger.error("Html邮件发送异常！", e);
return "failure";
}
}
/**
* @Description http://localhost:8888/sendFilesMail
* @method 发送附件邮件
* @return
*/
@RequestMapping("/sendFilesMail")
public String sendFilesMail() {
String filePath = "F:\\select_from_user.sql";
MimeMessage message = javaMailSender.createMimeMessage();
try {
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(sender);
helper.setTo(receiver);
helper.setSubject("邪客发送附件邮件测试");
helper.setText("一封带附件的邮件", true);
FileSystemResource file = new FileSystemResource(new File(filePath));
String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
helper.addAttachment(fileName, file);
javaMailSender.send(message);
logger.info("附件邮件发送成功！");
return "success";
} catch (MessagingException e) {
logger.error("附件邮件发送异常！", e);
return "failure";
}
}
/**
* @Description http://localhost:8888/sendInlineResourceMail
* @method 发送图片邮件
* @return
*/
@RequestMapping("/sendInlineResourceMail")
public String sendInlineResourceMail() {
String id = "xieke90";
// cid:内嵌资源
String content = "带有图片的邮件：![](\'cid:")
";
String imgPath = "F:\\spring-cloud.png";
MimeMessage message = javaMailSender.createMimeMessage();
try {
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(sender);
helper.setTo(receiver);
helper.setSubject("邪客发送图片邮件测试");
helper.setText(content, true);
FileSystemResource res = new FileSystemResource(new File(imgPath));
helper.addInline(id, res);
javaMailSender.send(message);
logger.info("图片邮件发送成功！");
return "success";
} catch (MessagingException e) {
logger.error("图片邮件发送异常！", e);
return "failure";
}
}
}
四、分别测试文本、Html、附件、图片邮件发送
<1>、访问http://localhost:8888/sendMail，测试结果如下：
<2>、访问http://localhost:8888/sendHtmlMail，测试结果如下：
<3>、访问http://localhost:8888/sendFilesMail，测试结果如下：
<4>、访问http://localhost:8888/sendInlineResourceMail，测试结果如下：
