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
问题描述：运行spring cloud子项目出现以上异常。
问题分析：英语水平有限，大致可以看出zipkin相关的东西注册不了，而zipkin不是自己写的代码。
解决问题：综合上述，加上最近几天碰了好几次上面的现象，得出的结论是依赖之间的版本不匹配。建议对照maven repository调整相关依赖的版本。
