Introduction:

ExceptionMapper is an implementation of JAX-RS exception. It allows you to use customized exception.

Provider

@Provider is a JAX-RS annotation that tells JAX-RS that you want use some customized implementation instead of default.

Usage

The basic usage is override the toResponse Method.

In specific, if you want to map the ClientErrorException, pick the type as ClientErrorException in the implements.

public class ClientExceptionMapper implements ExceptionMapper<ClientErrorException> {
    @Override
    public Response toResponse(final ClientErrorException exception) {
	// Customize the exception
    }
}

In this case, all the ClientErrorException will be mapped to the new class.
