Answer 1

This code will add ability to use your exceptions controlled advice.

@Before
public void setup() {
    this.mockMvc = standaloneSetup(commandsController)
        .setHandlerExceptionResolvers(withExceptionControllerAdvice())
        .setMessageConverters(new MappingJackson2HttpMessageConverter()).build();
}

private ExceptionHandlerExceptionResolver withExceptionControllerAdvice() {
    final ExceptionHandlerExceptionResolver exceptionResolver = new ExceptionHandlerExceptionResolver() {
        @Override
        protected ServletInvocableHandlerMethod getExceptionHandlerMethod(final HandlerMethod handlerMethod,
            final Exception exception) {
            Method method = new ExceptionHandlerMethodResolver(ExceptionController.class).resolveMethod(exception);
            if (method != null) {
                return new ServletInvocableHandlerMethod(new ExceptionController(), method);
            }
            return super.getExceptionHandlerMethod(handlerMethod, exception);
        }
    };
    exceptionResolver.afterPropertiesSet();
    return exceptionResolver;
}
