Question

我需要设置＆＃34; Access-Control-Allow-Origin＆＃34;到＆＃34; *＆＃34;按代码。

阅读this我尝试使用org.eclipse.jetty.servlets.CrossOriginFilter设置setInitParameter：

        Server  server = new Server(activity.WEB_SERVER_PORT);  
        ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);

        context.setWelcomeFiles(new String[] { "index.html" });
        context.setContextPath("/");

        context.setInitParameter("org.eclipse.jetty.servlets.CrossOriginFilter", "/*");

        TheServlet sv = new TheServlet();
        context.addServlet(new ServletHolder(sv),"/servleturl");

        server.setHandler(context); 
        try {
            server.start();
        } catch (Exception e) { }

但它不起作用。我怎么解决？

尝试将addFilter方法与filterHolder一起使用。这段代码可能会有所帮助

    FilterHolder filterHolder = new FilterHolder(CrossOriginFilter.class);
    filterHolder.setInitParameter("allowedOrigins", "*");
    filterHolder.setInitParameter("allowedMethods", "GET, POST");

    ServletContextHandler servletContextHandler;
    servletContextHandler = new ServletContextHandler(webServer, "/", ServletContextHandler.SESSIONS);
    servletContextHandler.addServlet(atmosphereServletHolder, "/atmosphere/*");
    servletContextHandler.addServlet(jerseyServletHolder, "/jersey/*");
    servletContextHandler.addFilter(filterHolder, "/*", null);

在Jetty中设置Access-Control-Allow-Origin
