com.google.cloud.spring.logging.TraceIdLoggingWebMvcInterceptor

All Implemented Interfaces:

org.springframework.web.servlet.HandlerInterceptor

public class TraceIdLoggingWebMvcInterceptor
extends Object
implements org.springframework.web.servlet.HandlerInterceptor

HandlerInterceptor that extracts the request trace ID from the "x-cloud-trace-context" HTTP header and stores it in a thread-local using TraceIdLoggingEnhancer.setCurrentTraceId(java.lang.String).
