使用步骤：

maven添加该项目jar包（自己打包安装到本地仓库）

        <dependency>
            <groupId>io.zipkin.brave</groupId>
            <artifactId>brave-dubbo</artifactId>
            <version>1.0.0-SNAPSHOT</version>
        </dependency>

spring中配置

• 打印日志方式

        <bean id="brave" class="com.github.kristofa.brave.dubbo.BraveFactoryBean" p:serviceName="serviceName" p:zipkinHost="" p:rate="1.0" />

• http方式

        <bean id="brave" class="com.github.kristofa.brave.dubbo.BraveFactoryBean" p:serviceName="serviceName" p:zipkinHost="http://10.168.16.111:9411/" p:rate="1.0" />
