类 DubboInterceptor

java.lang.Object

org.apache.skywalking.apm.plugin.asf.dubbo.DubboInterceptor

所有已实现的接口:

org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.InstanceMethodsAroundInterceptor

public class DubboInterceptor
extends Object
implements org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.InstanceMethodsAroundInterceptor
