1.导包

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

2.配置

spring.mail.username=2545644870@qq.com
spring.mail.password=gmxawscfvzvoecjc
spring.mail.host=smtp.qq.com
#开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=true

3.编写测试

import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;

import java.io.File;

@SpringBootTest

        message.setTo("2545644870@qq.com");
        message.setFrom("2545644870@qq.com");

        mailSender.send(message);
    }
    @Test

        mailSender.send(mimeMessage);
    }
    //封装成一个方法
