How to remove a groovy filter from zuul (filterRegistry)?

[MAAARKIN]

Currently i put my .groovy zuulfilter in the folder and they are added to my gateway but how to remove this filter dynamically, how can i do that?

looking in the source code FilterLoader.java has putFilter(File file) but not removeFilter(File file).

its possible to remove?

@artgon, If I want to add a new route to Zuul my understanding is that one of the ways to do that would be to drop a Groovy file in the filters folder. Is this the only way today or is there a better way to do this? @MAAARKIN do you have an idea?

putFilter(File file) of FilterLoader wil first remove previous registration of the plugin provided by the given file. Then it will try to register it again. Here the trick comes: If you place in the filters folder a file with the same name but not containing a valid class, zuul will unregister your filter and then will fail to register it again throwing corresponding exception. This is of course not nice, so a better option is to make the filter class "abstract". Zuul will check this before registering the filter again and if it is true, the will silently exit the registration method.
