Spring 3 MVC Interceptor tutorial with example

Spring MVC provides a powerful mechanism to intercept an http request. Similar to Servlet Filter concept, Spring MVC provides a way to define special classes called Interceptors that gets called before and after a request is served.

Quick Overview

Each interceptor you define must implement org.springframework.web.servlet.HandlerInterceptor interface. There are three methods that need to be implemented.

preHandle(..) is called before the actual handler is executed;

The preHandle(..) method returns a boolean value. You can use this method to break or continue the processing of the execution chain. When this method returns true, the handler execution chain will continue; when it returns false, the DispatcherServlet assumes the interceptor itself has taken care of requests (and, for example, rendered an appropriate view) and does not continue executing the other interceptors and the actual handler in the execution chain.

postHandle(..) is called after the handler is executed;

afterCompletion(..) is called after the complete request has finished.

These three methods should provide enough flexibility to do all kinds of preprocessing and postprocessing.

You can define an interceptor class as follow:

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

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

public class HelloWorldInterceptor implements HandlerInterceptor  {
	public boolean preHandle(HttpServletRequest request,
			HttpServletResponse response, Object handler) throws Exception {
		return true;
	//override postHandle() and afterCompletion() 

Once the interceptor is defined, you can ask Spring MVC to configure it via <mvc:interceptors> tag within spring-servlet.xml file.

      <bean class="net.viralpatel.spring3.interceptor.HelloWorldInterceptor" />

Let us start with the complete Demo application. We will create a demo Interceptor that logs each request.

Tools and technologies:

  1. Java 5 (or above)
  2. Spring MVC 3.0 (or above)
  3. Eclipse 3.2 (or above)

We will need following JAR files in order to execute this project.

If you are using Apache Maven as dependency management, add following dependencies to pom.xml.


Let us create a simple Spring MVC Interceptor class that logs each request.

Step 1: The Controller – Create new Spring MVC Controller

We create a simple Spring MVC controller that displays a plain JSP view.


package net.viralpatel.spring3.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

public class HelloWorldController {

	@RequestMapping(value = "/hello", method = RequestMethod.GET)
	public String sayHello() {
		return "hello";

The controller has one method sayHello() which is mapped to URL /hello using @RequestMapping. This simply paints the hello.jsp view.

Step 2: The View – Create new JSPs

Create two JSPs, hello.jsp that displays hello message and index.jsp that simply redirects first request to /hello.html.


	<title>Spring MVC Interceptor example</title>


<jsp:forward page="hello.html"></jsp:forward>

The index.jsp simply redirects to hello.html which calls the HelloWorldController.

Step 3: The Interceptor – Spring MVC HandlerInterceptor

Let’s create the Spring based Handler Interceptor which will intercept the request and print a message.


package net.viralpatel.spring3.interceptor;

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

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

public class HelloWorldInterceptor implements HandlerInterceptor  {
	public boolean preHandle(HttpServletRequest request,
			HttpServletResponse response, Object handler) throws Exception {
		return true;
	public void postHandle(HttpServletRequest request,
			HttpServletResponse response, Object handler,
			ModelAndView modelAndView) throws Exception {
	public void afterCompletion(HttpServletRequest request,
			HttpServletResponse response, Object handler, Exception ex)
			throws Exception {
		System.out.println("After completion handle");

Thus in each of the method preHandle, postHandle and afterCompletion we print a message on console.

Step 4: Spring Configuration

Now lets glue up the source code and configure Spring. Note how we declared the interceptor in spring-servlet.xml using <mvc:interceptors> tag.


<beans xmlns="http://www.springframework.org/schema/beans"
	xsi:schemaLocation="http://www.springframework.org/schema/beans	http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context	http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
	<context:annotation-config />
	<context:component-scan base-package="net.viralpatel.spring3.controller"/>
      <bean class="net.viralpatel.spring3.interceptor.HelloWorldInterceptor" />
  <bean id="jspViewResolver"
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />

Also configure the spring’s DispatcherServlet in web.xml file.


<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	id="WebApp_ID" version="2.5">
	<display-name>Spring3MVC-Interceptor example</display-name>

Final Project Structure

Once all the source files and configuration files are in place, your project should look like below:



Compile and execute the project in Eclipse. Open below URL in browser.

    Please help


  14. Mounika says:

    Can you please tell me the real time applications where we will use interceptors most..? What is use of pre handling, or post handling the requests. Please Explain me with any real time scenarios. Thanks in advance.

    • Michael C. says:

      I can tell you what I use a HandlerInterceptor for. In my application, which is an e-commerce engine, I use a HandlerInterceptor to resolve certain things that all controllers will need to have at their disposal before they can render a response. I initialize certain things like the particular store they’re accessing, the user’s shopping cart, navigation UI, robots rules, client timezone, etc. If I didn’t do those things inside an interceptor, then I would have to do repeat all of those initializations inside of each controller method, which would make my code a lot more redundant and less readable. Whatever you find yourself repeating a lot in controller methods can be factored out and handled inside an interceptor. I hope that gives you some more insight.

    • raju says:


      These ‘interceptors’ are useful to validate requests from client.
      For Eg:
      It is useful to avoid spam requests By Validating the request according to Your app Requirements(You allow the request to Process Furthur only it has perticuls credentials).
      And you can Provide Secirity by Restricting the invalid requests to access the resources of your App.

      Thanks & Regards

    • krishna says:

      we will interceptors used for setMaxAgeForSession, checkIfRequestIsAllowedWithoutLogIn some other purposes…

  15. Michael C. says:

    Do you know of a way to intercept requests BEFORE a handler has been chosen? The reason I want to know is because some parts of my application have dynamic URLs (neither in XML nor in @RequestMapping annotations) that are stored in a database and updated via a web front-end. As such, static URL-to-controller mappings won’t work in my case (think of an app like a CMS where end users can choose their own URL for a particular page). Any ideas?

    What if I want to inject interceptor logic for a certain method on a certain controller? Is there an easy to to achieve that? Literally I am looking for something like @Before or @After annotation in PlayFramework (see http://www.playframework.com/documentation/1.2/controllers#interceptions) in spring

  22. Knight says:


    Really nice tutorial. I understood the whole concept. I only dont understand where have we linked the interceptor to handler. I mean how does the framework know that the HelloWorldInterceptor is to be called for request to HelloWorldController controller

  25. Rajesh says:

    Nice article Viral.
    Sometime back I implemented a timestamp ‘Filter’ which would take start timestamp when user enters the filter and another end timestamp just before returning the response. Since these timestamps were in the same method, I calculated the time taken to complete the request and was able to log it to file along with the request parameter.

    How can I achieve it using interceptors ? (Since pre and post are separate methods, the local variable values are lost). I am relatively new to Spring so if there’s another way ..please point me to it.
    Regards, Rajesh
