Dropwizard Path: Get all paths in app

Question

Does anyone know how to get the same information, about what paths are used, like at the start of dw application. I mean the output after this line:

io.dropwizard.jersey.DropwizardResourceConfig: The following paths were found for the configured resources:
GET     /path/of/res/test (this.is.the.class.package.info.MyRessource)
POST     /path/of/res/test2 (this.is.the.class.package.info.MyRessource2)

I have to check if specific path exists.

You'll have to do this on your own. Take a look at the logEndpoints method (which is what actually logs this information - with private methods). You should be able to adapt this method to handle the resources from your environment.jersey().getResourceConfig() after you configure your resources in your run method.

Something like:

final ImmutableList.Builder<Class<?>> builder = ImmutableList.builder();
for (Object o : environment.jersey().getResourceConfig().getSingletons()) {
  if (o.getClass().isAnnotationPresent(Path.class)) {
    builder.add(o.getClass());
  }
}
for (Class<?> klass : environment.jersey().getResourceConfig().getClasses()) {
  if (klass.isAnnotationPresent(Path.class)) {
    builder.add(klass);
  }
}
final List<String> endpoints = Lists.newArrayList();
for (Class<?> klass : builder.build()) {
  AbstractResource resource = IntrospectionModeller.createResource(klass);
  endpoints.add(resource.getPath().getValue());
}

Note that what's in master is slightly ahead of what's in Maven - the above example shows how to get the AbstractResource which will work with 0.7.1. You'll have to be sure to adapt your method as dropwizard evolves. This example also doesn't normalize the path but I you can easily add that based on logEndpoints.
