spring boot配置zipkin时发生的问题

近段时间被这个问题折磨了很久，进入正题：

pom.xml开始时的依赖

 <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin</artifactId>
            <version>2.10.1</version>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-server</artifactId>
            <version>2.10.1</version>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-autoconfigure-ui</artifactId>
            <version>2.10.1</version>
        </dependency>

出现问题：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.

解决方案：把zipkin-autoconfigure-ui的版本改成如下：即可解决问题

        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-autoconfigure-ui</artifactId>
            <version>2.12.3</version>
        </dependency>

如果碰到启动后无法访问页面的情况，也可以试一下以上方法。
