从servlet到jsp的嵌入式码头

因此，我使用setWar和正确的jar来使其工作。使用此代码，可以直接寻址jsp（localhost：8080 /
result.jsp），更重要的是使用servlet（localhost：8080 /
hello）.forward命令将其转发到jsp。这将使我能够通过jsp提供一些动态内容。

代码如下…（注意：Embedded Jetty =>不需要web.xml）

import java.io.File;import java.io.IOException;import javax.servlet.RequestDispatcher;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.eclipse.jetty.server.Handler;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.server.handler.DefaultHandler;import org.eclipse.jetty.server.handler.HandlerList;import org.eclipse.jetty.servlet.ServletHolder;import org.eclipse.jetty.webapp.WebAppContext;public class RunHelloServlet {public static void main(String[] args) throws Exception {    System.setProperty("DEBUG", "true");    Server server = new Server(8080);    WebAppContext webappcontext = new WebAppContext();    webappcontext.setContextPath("/");    File warPath = new File("C:/dev/workspace/JettyTest", "src/main/webapp");    webappcontext.setWar(warPath.getAbsolutePath());    HandlerList handlers = new HandlerList();    webappcontext.addServlet(new ServletHolder(new HelloServlet()), "/hello");    handlers.setHandlers(new Handler[] { webappcontext, new DefaultHandler() });    server.setHandler(handlers);    server.start();}public static class HelloServlet extends HttpServlet {    private static final long serialVersionUID = 1L;    public HelloServlet() {    }    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {        // logic        try { request.getRequestDispatcher("/result.jsp").forward(request, response);        }        catch (Throwable e1) { e1.printStackTrace();        }    }}}
