使用springboot实现邮箱发送

一. 我们需要导入发送邮件 的依赖jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion>
<groupId>cn.et</groupId>
<artifactId>SPRINGBOOT-SENDMAIL</artifactId>
<version>0.0.1-SNAPSHOT</version>
<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>
</project>

二.  创建一个application.properties配置文件  配置访问邮箱的参数
spring.mail.default-encoding=UTF-8
spring.mail.host=smtp.163.com
spring.mail.password=密码 授权码
spring.mail.port=25
spring.mail.protocol=smtp
spring.mail.username=用户名

三. 创建一个controller 发送邮件的业务

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.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MailController {
@Autowired
private JavaMailSender jms;
@GetMapping("/send")
public String send(){
SimpleMailMessage mailMessage = new SimpleMailMessage();
//谁发的
mailMessage.setFrom("*******@163.com");
//发给谁
mailMessage.setTo("********@qq.com");
//标题
mailMessage.setSubject("我");
//内容
mailMessage.setText("逗你玩");
jms.send(mailMessage);
return "1";
}
}

四. 创建一个启动类  启动项目
package cn.et;

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

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


五.  在浏览器中访问 地址 http://localhost:8080/send
 返回 "1" 说明发送成功
