java - 如何在 geoserver 的 OWS 中获取 ModelAndView？

Question

我正在实施地理服务器的 OWS。我想得到如下specific method of the OWS：ModelAndView

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;

    public class HelloWorld {

      public HelloWorld() {
        // Do nothing
      }

      public ModelAndView sayHello(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException, Exception {
        ModelAndView m = new ModelAndView("index");

        return m;
      }
}

我该怎么做？
