場景：

1、 pom.xml 檔案中引入 sla jar 包中com.puhui.sla.OAuthServerConfig。

2、pom.xml 檔案中引入 cloud jar 包中com.puhui.cloud.config.OAuthServerConfig。

現象：

專案啟動報錯：

解決方案：

 在專案啟動主類中增加如下註解排除類。

 @ComponentScan(excludeFilters = {
         @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = OAuthServerConfig.class),
         @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = OAuthClientConfig.class) })
