com.networknt.traceability

Class TraceabilityHandler

java.lang.Object

com.networknt.traceability.TraceabilityHandler

All Implemented Interfaces:

com.networknt.handler.LightHttpHandler, com.networknt.handler.MiddlewareHandler, io.undertow.server.HttpHandler

public class TraceabilityHandler
extends Object
implements com.networknt.handler.MiddlewareHandler

This is a handler that checks if X-Traceability-Id exists in request header and put it into response header if it exists. The traceability-id is set by the consumer and it will be passed to all services and returned to the consumer eventually if there is no error. The AuditHandler will log it in audit log and Client will pass it to the next service. Dependencies: AuditHandler, Client
