Class BeelineHandlerInterceptor

java.lang.Object

org.springframework.web.servlet.handler.HandlerInterceptorAdapter

io.honeycomb.beeline.spring.beans.BeelineHandlerInterceptor

public class BeelineHandlerInterceptor
extends org.springframework.web.servlet.handler.HandlerInterceptorAdapter

The interceptor is coupled to the SpringServletFilter and requires it to have set up the thread local context via the Tracer.

The purpose of this is to add additional fields to the web application's "root" Span that are not yet available within a Servlet Filter. Namely, information about the handler mapping.

For details about the execution flow see the Javadoc of the super classes and the SpringServletFilter.
