Spring - get request URI from WebRequest

In this short article, we would like to show how to get a request URI from WebRequest.

Quick solution:

WebRequest webRequest = ...

String requestUri = ((ServletWebRequest)webRequest).getRequest().getRequestURI();

Practical example

Request URI can be useful when we work with interceptors.

RequestUtils.java file:

package com.example.config;

import org.springframework.web.context.request.ServletWebRequest;
import org.springframework.web.context.request.WebRequest;

import javax.servlet.http.HttpServletRequest;

public class RequestUtils {

    public static String getRequestUri(WebRequest webRequest)
    {
        HttpServletRequest servletRequest = ((ServletWebRequest)webRequest).getRequest();

        return httpServletRequest.getRequestURI();
    }
}

Usage example:

package com.example.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.ui.ModelMap;
import org.springframework.web.context.request.ServletWebRequest;
import org.springframework.web.context.request.WebRequest;
import org.springframework.web.context.request.WebRequestInterceptor;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;

import javax.servlet.http.HttpServletRequest;

@Configuration
public class WebConfig implements WebMvcConfigurer
{
    @Override
    public void addInterceptors(InterceptorRegistry registry)
    {
        registry.addWebRequestInterceptor(new WebRequestInterceptor() {

            @Override
            public void preHandle(WebRequest request) throws Exception {
                String requestUri = RequestUtils.getRequestUri(request); // <-- Request URI
                System.out.println("requestUri=" + requestUri);
            }

            @Override
            public void postHandle(WebRequest request, ModelMap model) throws Exception {
                // some code here ...
            }

            @Override
            public void afterCompletion(WebRequest request, Exception ex) throws Exception {
                // some code here ...
            }
        });
    }
}
