Usage of @ControllerAdvice Sample:

package com.concretepage.controller;
import java.io.IOException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.servlet.ModelAndView;
import com.concretepage.exception.KeywordNotFoundException;
@ControllerAdvice
public class GlobalExceptionHandler {
      @ExceptionHandler(IOException.class)
      public ModelAndView myError(Exception exception) {
        System.out.println("----Caught IOException----");
        ModelAndView mav = new ModelAndView();
        mav.addObject("exception", exception);
        mav.setViewName("globalerror");
        return mav;
      }
      @ExceptionHandler(KeywordNotFoundException.class)
      public String notFound() {
            System.out.println("----Caught KeywordNotFoundException----");
            return "404";
      }
}

Usage of HandlerExceptionResolver Sample:

package com.logicbig.example;

import org.springframework.context.annotation.Bean;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@EnableWebMvc
public class Config {

    @Bean
    HandlerExceptionResolver errorHandler () {
        return new HandlerExceptionResolver() {
            @Override
            public ModelAndView resolveException (HttpServletRequest request,
                                                  HttpServletResponse response,
                                                  Object handler,
                                                  Exception ex) {
                ModelAndView model = new ModelAndView("error-page");
                model.addObject("exceptionType", ex);
                model.addObject("handlerMethod", handler);
                return model;
            }
        };
    }
