public class ShutdownHandler
extends AbstractHandler

A handler that shuts the server down on a valid request. Used to do "soft" restarts from Java. If _exitJvm ist set to true a hard System.exit() call is being made. This handler is a contribution from Johannes Brodwall: https://bugs.eclipse.org/bugs/show_bug.cgi?id=357687 Usage:

    Server server = new Server(8080);
    HandlerList handlers = new HandlerList();
    handlers.setHandlers(new Handler[]
    { someOtherHandler, new ShutdownHandler(server,"secret password") });
    server.setHandler(handlers);
    server.start();
   

   public static void attemptShutdown(int port, String shutdownCookie) {
        try {
            URL url = new URL("http://localhost:" + port + "/shutdown?token=" + shutdownCookie);
            HttpURLConnection connection = (HttpURLConnection)url.openConnection();
            connection.setRequestMethod("POST");
            connection.getResponseCode();
            logger.info("Shutting down " + url + ": " + connection.getResponseMessage());
        } catch (SocketException e) {
            logger.debug("Not running");
            // Okay - the server is not running
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

构造方法详细信息

ShutdownHandler

public ShutdownHandler(Server server,
                       String shutdownToken)

Creates a listener that lets the server be shut down remotely (but only from localhost).

参数：

server - the Jetty instance that should be shut down

shutdownToken - a secret password to avoid unauthorized shutdown attempts

方法详细信息

handle

public void handle(String target,
                   Request baseRequest,
                   HttpServletRequest request,
                   HttpServletResponse response)
            throws IOException,
                   ServletException

从接口 Handler 复制的描述

Handle a request.

参数：

target - The target of the request - either a URI or a name.

baseRequest - The original unwrapped request object.

request - The request either as the Request object or a wrapper of that request. The AbstractHttpConnection.getCurrentConnection() method can be used access the Request object if required.

response - The response as the Response object or a wrapper of that request. The AbstractHttpConnection.getCurrentConnection() method can be used access the Response object if required.

抛出：

IOException

ServletException

getRemoteAddr

protected String getRemoteAddr(HttpServletRequest request)

setExitJvm

public void setExitJvm(boolean exitJvm)
