springboot +maven 啟動時報錯：
Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[]]
NoClassDefFoundError: javax/annotation/security/DeclareRoles
解決辦法：
添加依賴項：
<dependency>
<groupId>javax.annotation</groupId>
<artifactId>javax.annotation-api</artifactId>
<version>1.2</version>
</dependency>
