Springboot實現Java郵件任務

1.maven引入依賴

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

2.application.properties配置發送郵箱
//用戶郵箱
spring.mail.username=753029781@qq.com

//QQ郵箱開通第三方登陸的受權碼
spring.mail.password=xxxxxxxxxxxx

//主機地址
spring.mail.host=smtp.qq.com

//開啓安全的鏈接
spring.mail.properties.mail.smtp.enable=true

3.測試
