首先建立一個郵箱,建議@126.com   @163.com   @qq.com都可以

開啟smtp,一下是使用圖解:

在pom.xml中引入依賴:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.0.3.RELEASE</version>
        </dependency>

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

@SpringBootApplication
public class MialApplication {

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

package com.mial;

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;

/**
 * @Title: MailController
 * @ProjectName mail
 * @Description: TODO
 * @Author: yufei
 * @Date 2018/9/26 11:52
 */
@RestController
public class MailController {

    @Autowired
    JavaMailSender jms;

    @GetMapping("/send")
    public String send() {

        SimpleMailMessage mailMessage = new SimpleMailMessage();

        mailMessage.setFrom("******@163.com");

        mailMessage.setTo("******@qq.com");

        mailMessage.setSubject("測試郵件");

        mailMessage.setText("Hello World");

        jms.send(mailMessage);

        return "1";
    }
}
 

在application.properties中:

spring.mail.default-encoding=UTF-8
spring.mail.host=smtp.163.com
# 郵箱密碼
spring.mail.password=******
# 埠
spring.mail.port=25
# 協議
spring.mail.protocol=smtp
# 傳送郵箱的賬號
spring.mail.username=******@163.com
server.port=8081

執行main方法,訪問http://localhost:8081/send 出現1測試成功
