Not possible to register WebApp name/key properly when using WebRequestTrackingFilter in Spring boot

[gdahlin]

Hi,

When using the WebRequestTrackingFilter with a Spring boot application on the root context path the filter cannot register the web app name/key properly:

AI: ERROR 30-01-2017 12:15, 22: WebApp name is not found, unable to register WebApp
AI: INFO 30-01-2017 12:15, 22: Successfully registered the filter 'ApplicationInsightsWebFilter

This seem to be due to dependencies to either having a (non-root) servlet context path set for the app or that the app is found under a class-loading path containing "WEB-INF", which is not the case for this Spring boot app.

Would be good if the initialisation config could read either the spring boot app name or to have some external configuration value to set for the web app name/key.

Thanks in advance

I managed to fix that by implementing wrappers for WebRequestTrackingFilter, FilterContext and ServletContext classes, but that was a dirty hack...
Strange that such parameter has not been added from the very beginning...

Yes, I'm getting the same error. It's not an enhancement IMO. Seems like a bug (e.g. if I used a modern .NET app and AppInsights failed to register, it'd probably be assumed to be a bug)

@tomaszglinski What was the work around that you did?

[tomaszglinski]

@twsouthwick I think I extended the mentioned classes to pass required parameter. Cannot say exactly, cause I removed that (I was only playing, I resigned from App insights because of those troubles)

fixed in #449 with a public constructor to register the name of spring boot application. Later we will take the approach of #461 for better SpringBoot Integration.
