Is there any way to set an global exception handler for HTTP server

[Han He]

I want to return a server error (503) to client side when there is an exception raised inside the request handler. Currently I got the following error message in the log. And client side wait a long time to timeout..

2017-08-22 15:20:19  [ vert.x-eventloop-thread-5:32930 ] - [ ERROR ]

  Unhandled exception

java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to java.lang.CharSequence

 I googled, and found the failureHandler, but it was not called when the exception raised. The exception is thrown inside a result callback of a mongodb query when parsing the JsonObject.

Just wondering if there is an exception handler for this situation so we can return a server error to client instead of making client waiting for a long timeout.

Thanks,

Han

Hi,

you can set an exception handler on the Context of the Verticle that will raise any uncaught exception in this context.

Thanks a lot for your advice. It worked. I managed to set the exception handler for the context which handles the http request and then return a server error to client.
