Spring Boot Adding Http Request Interceptors

🚀 Adding Http Request Interceptors in Spring Boot

Are you struggling to find the right way to add HttpRequest interceptors in your Spring Boot application? 🤔 Do you want to log requests and responses for every HTTP request? You're not alone! Many developers face this challenge as the Spring Boot documentation does not cover this topic extensively. But worry not, we're here to help! 😄

The Problem

The lack of coverage in the Spring Boot documentation can make it difficult to understand how to add HttpRequest interceptors. Additionally, some examples found online are based on older versions of Spring and use applicationcontext.xml, which may not be relevant to your Spring Boot application. 📚

The Solution

Fortunately, there is a straightforward solution to achieve what you want in Spring Boot. Here's a step-by-step guide to adding HttpRequest interceptors:

1. Create a class that implements the HandlerInterceptor interface. Let's call it LoggingInterceptor. This class will define the logic to log requests and responses.

   import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class LoggingInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { // Log the incoming request here return true; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { // Log the response here } }

2. Register the LoggingInterceptor in your Spring Boot configuration file. Open the WebMvcConfigurer class and override the addInterceptors method.

   import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; @Configuration public class WebConfig implements WebMvcConfigurer { @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new LoggingInterceptor()); } }

That's it! 🎉 You have successfully added an HttpRequest interceptor to your Spring Boot application. The LoggingInterceptor class will now log requests and responses for every HTTP request.

Bonus Tip - Customizing the LoggingInterceptor

If you want to customize the logging behavior for different endpoints or HTTP methods, you can modify the LoggingInterceptor class accordingly. For example, you can check the request URL or method and log based on specific conditions.

Conclusion

Adding HttpRequest interceptors in Spring Boot can be a bit tricky due to the lack of explicit documentation. However, by following the steps outlined in this guide, you can easily log requests and responses for every HTTP request in your application.
