All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class HttpEchoServlet
extends javax.servlet.http.HttpServlet

An HttpServlet to echo the HttpServletRequest with headers and payload as HTML output in the HttpServletResponse. This is very helpful especially if your application is behind a complex infrastructure with reverse-proxies, etc.
In order to use this servlet simply add the following to your spring configuration (and adjust "/debug/echo/*" to your needs):

 @Bean
 public ServletRegistrationBean echoServletRegistration() {

   HttpEchoServlet echoServlet = new HttpEchoServlet();
   ServletRegistrationBean registration = new ServletRegistrationBean(echoServlet);
   registration.addUrlMappings("/debug/echo/*");
   return registration;
 }
