springboot发送邮件案例

首先创建一个邮箱账号，建议@126.com，@163.com，@qq.com 都可以

开启smtp，以下是使用图解：

创建maven项目在pom.xml引入依赖：

<parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>1.5.9.RELEASE</version>
   </parent>

   <dependencies>
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
       </dependency>
       
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-mail</artifactId>
       </dependency>

   </dependencies>

package cn.et;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Test {
   public static void main(String[] args) {
       SpringApplication.run(Test.class, args);
   }
}

package cn.et;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MailController {

   @Autowired
   JavaMailSender jms;

   @GetMapping("/send")
   public String send(){
       //建立邮件消息
       SimpleMailMessage mainMessage = new SimpleMailMessage();
       //发送者
       mainMessage.setFrom("[email protected]");
       //接收者
       mainMessage.setTo("[email protected]");
       //发送的标题
       mainMessage.setSubject("嗨喽");
       //发送的内容
       mainMessage.setText("hello world");
       jms.send(mainMessage);
       return "1";
   }
}

在application.properties中：

spring.mail.default-encoding=UTF-8
spring.mail.host=smtp.qq.com
#发送者的邮箱账号
spring.mail.username=1***@qq.com
#这里要用邀请码，不是你登录邮箱的密码
spring.mail.password=******
#端口
spring.mail.port=465
#协议
spring.mail.protocol=smtp
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.debug=true

运行main方法，访问http://localhost:8081/send 出现1测试成功。
