Description: The bean 'characterEncodingFilter', defined in class path resource [zipkin/autoconfigure/ui/ZipkinUiAutoConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/HttpEncodingAutoConfiguration.class] and overriding is disabled. Action: Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
問題描述：運行spring cloud子項目出現以上異常。
問題分析：英語水平有限，大致可以看出zipkin相關的東西注冊不了，而zipkin不是自己寫的代碼。
解決問題：綜合上述，加上最近幾天碰了好幾次上面的現象，得出的結論是依賴之間的版本不匹配。建議對照maven repository調整相關依賴的版本。
