Spring @RequestAttribute annotation – Spring MVC

Spring 4.3 provides a new @RequestAttribute annotation that helps us access to pre-existing global request attributes (outside the controller). Today we’re gonna look at how to get a HttpServletRequest attribute which is created in an Interceptor using Spring @RequestAttribute annotation.

Instead of using HttpServletRequest object, we can bind attribute from a javax.servlet.http.HttpServletRequest to a handler method parameter by using @RequestAttribute annotation on that parameter:

In the example, to have a pre-existing request attribute which are managed globally, we create an Interceptor and focus on preHandle() method:

So, we’re gonna look at the next part of this tutorial to know how to get Counter attribute from HttpServletRequest with attribute created in preHandle() method.


– Java 1.8
– Maven 3.3.9
– Spring Tool Suite – Version 3.8.1.RELEASE
– Spring Boot: 1.5.1.RELEASE

Project Structure:

Now follow step by step:

1. Create Spring Boot project and add Dependency

– Open Spring Tool Suite, on Menu, choose File -> New -> Spring Starter Project, then fill each fields.
– Click Next, then Finish. Spring Boot project will be created successfully.
– Add dependency to pom.xml:

2. Create Data Model class

Under package model, create Counter class, this class will be used for request attribute:

3. Create and add Interceptor class

Under package config, create CounterInterceptor class that implements HandlerInterceptor. For simplifying the example, we only focus on writing code for preHandle() method:

We set Attribute Counter for HttpServletRequest with value START_COUNT. This value will be kept when Counter attribute is bound to handle() method of Web Controller.

Next, create a @Configuration component to add the Interceptor above:

4. Create a WebController

Under package controller, create WebController class:

Everytime we send a request, @RequestAttribute named “counter” will be bound.

5. Run Spring Boot Application & Enjoy Result

– Config maven build:
clean install
– Run project with mode Spring Boot App
– Check results:

Send request: http://localhost:8080/
System shows:

Web Browser:

It means we got request attribute counter with value 9 successfully and increased it.
