Springboot郵件發送配置

pom.xml依賴：

<dependency><groupId>org.eclipse.angus</groupId><artifactId>jakarta.mail</artifactId><version>2.0.3</version>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>

yml:

email:user: 發送郵箱地址code: 郵箱授權碼（QQ、網易郵箱等的授權碼可百度獲取）host: smtp.126.com或smtp.qq.com，不同郵箱配置不同auth: true

啟程程序，發送請求：localhost:8080/send

查看郵箱，收到測試郵件。
