Gzip specific controller in Spring MVC

Question

Is there a way to add Gzip for one method or controller in spring

@RequestMapping(value = "/system", method = {RequestMethod.GET})
@Gzip //<- Something similar this,
public ApiResponse status() throws Exception{

}

I dont want to enable it for the entire server using tomcat configuration, since my clients are not yet ready for consuming gzip,

But these all examples are explaining to gzip at filter level, I am looking to have the decision at my controller or controller method level — Ysak

You can put java.io.OutputStream or javax.servlet.http.HttpServletResponse (for specific gzip HTTP headers) to your Controller method as parameter wrapping it with java.util.zip.GZIPOutputStream before writing the content to the client

@RequestMapping(value = "/system", method = {RequestMethod.GET})
public void status(HttpServletResponse response) throws Exception {
   try(GZIPOutputStream out = new GZIPOutputStream(response.getOutputStream())) {
       // write to out the content
   }
}
