How to extract IP Address in Spring MVC Controller get call?

Question

I am working on Spring MVC controller project in which I am making a GET URL call from the browser -

Below is the url by which I am making a GET call from the browse

Answer 1

In my case, I was using Nginx in front of my application with the following configuration:

location / {
     proxy_pass        http://localhost:8080/;
     proxy_set_header  X-Real-IP $remote_addr;
     proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header  Host $http_host;
     add_header Content-Security-Policy 'upgrade-insecure-requests';
}

so in my application I get the real user ip like so:

String clientIP = request.getHeader("X-Real-IP");
