Class HandleRequestInterceptor

java.lang.Object

org.apache.skywalking.apm.plugin.light4j.HandleRequestInterceptor

All Implemented Interfaces:

InstanceMethodsAroundInterceptor

public class HandleRequestInterceptor
extends Object
implements InstanceMethodsAroundInterceptor

HandleRequestInterceptor creates an entry span before the execution of ExceptionHandler.handleRequest(HttpServerExchange) in the I/O thread.

If the Config.Plugin.Light4J#TRACE_HANDLER_CHAIN flag is set, additionally a local span is produced for each MiddlewareHandler and business handler before their respective HttpHandler.handleRequest(HttpServerExchange) method executes. Since LightHttpHandler is implemented by various middleware and business handlers and the Light4J framework delegates to these in succession, a chain of LocalSpans will be produced.
