Spring Boot is a widely used framework for developing Java applications. It provides a lot of features and out-of-the-box solutions that help developers build applications quickly and easily. One of the key features of Spring Boot is the ability to add HTTP request interceptors, which can help you to handle requests and responses in a more effective way. In this blog post, we’ll be discussing what HTTP request interceptors are, why they’re important, and how to add them in your Spring Boot application.

What are Http Request Interceptors?

HTTP request interceptors are components that can process HTTP requests and responses before they reach their intended targets. They can be used to perform a variety of tasks such as logging, authentication, or adding custom headers. In Spring Boot, HTTP request interceptors are implemented as beans that implement the HandlerInterceptor interface.

Why are Http Request Interceptors Important?

HTTP request interceptors can help you to handle requests and responses in a more effective way. For example, if you want to log all incoming requests to your application, you can use an HTTP request interceptor to log the request before it reaches its intended target. Similarly, if you want to add custom headers to all responses, you can use an HTTP request interceptor to do so.

Adding Http Request Interceptors in Spring Boot

In this section, we’ll be discussing how to add HTTP request interceptors in your Spring Boot application. There are two steps involved in adding an HTTP request interceptor:

Implement the HandlerInterceptor interface:

The first step is to implement the HandlerInterceptor interface. You can do this by creating a new class and implementing the required methods. Here’s an example of a basic HTTP request interceptor that logs incoming requests:

import org.springframework.web.servlet.HandlerInterceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class LoggingInterceptor implements HandlerInterceptor {

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
        System.out.println("Incoming request: " + request.getRequestURI());
        return true;

Register the interceptor:

The second step is to register the interceptor. You can do this by adding the interceptor to the list of interceptors in your Spring Boot application. Here’s an example of how to register the LoggingInterceptor in your application:

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

public class WebConfig implements WebMvcConfigurer {

    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LoggingInterceptor());

Additionally, HTTP request interceptors can also be used to add common functionalities to multiple parts of the application without repeating the code. This can improve the maintainability of your application and make it easier to add or modify functionalities in the future. It is always a good practice to separate the concerns of different parts of the application, and HTTP request interceptors can help you achieve this.


In this blog post, we discussed what HTTP request interceptors are and why they’re important. We also showed you how to add HTTP request interceptors in your Spring Boot application. HTTP request interceptors are a powerful feature that can help you handle requests and responses in a more effective way. If you’re interested in learning more about Spring Boot, be sure to check out the official documentation and other resources available online. With the help of HTTP request interceptors, you can improve the performance, security, and overall functionality of your Spring Boot application. Whether you’re a seasoned developer or just starting out, incorporating HTTP request interceptors into your Spring Boot workflow is a great way to take your skills to the next level.
