Grizzly:非法尝试超过配置的最大页眉数

Question

我在RESTful web服务服务器应用程序中使用Grizzly/泽西/Jackson。对于某些交互，可能会在响应中返回大量HTTP报头。默认情况下，Grizzy将响应头的最大数目设置为100。

读取灰色Http服务器框架概述时，似乎可以以某种方式配置响应发送给客户端的最大头数(Http服务器框架概述)，但当Grizzly与泽西岛堆叠在一起时，还不清楚这是如何实现的。

对于如何设置此配置有任何建议吗？

这就是我目前配置Grizzly和Jackson的方式：

packages(true, Config.CONFIG_RESOURCE_BASE_PACKAGE);
register(JacksonFeature.class);
register(GrizzlyHttpContainerProvider.class);
register(CustomInjectables.class);
register(RolesAllowedDynamicFeature.class);
register(AccessSecurityFilter.class);

String host = Config.get("webserver.address");
int port = Config.getInteger("webserver.port");
boolean secure = Config.getBoolean("webserver.secure");

if (secure) {
    SSLContextConfigurator sslContextConfigurator = new SSLContextConfigurator();
    sslContextConfigurator.setKeyStoreFile(Config
            .get("webserver.keystore.location"));
    sslContextConfigurator.setKeyStorePass(Config
            .get("webserver.keystore.password"));

    boolean clientMode = false;
    boolean needClientAuth = false;
    boolean wantClientAuth = false;
    SSLEngineConfigurator sslEngineConfigurator = new SSLEngineConfigurator(
            sslContextConfigurator, clientMode, needClientAuth,
            wantClientAuth);

    URI uri = URI.create("https://" + host + ":" + port);
    log.info("Starting web server (secure): " + uri + " ...");
    server = GrizzlyHttpServerFactory.createHttpServer(uri, this, true,
            sslEngineConfigurator, true);
} else {
    URI uri = URI.create("http://" + host + ":" + port);
    log.info("Starting web server: " + uri + " ...");
    server = GrizzlyHttpServerFactory.createHttpServer(uri, this, true);
}

这是当我超过响应头的最大数量时的堆栈：

您需要做的第一件事是，当您调用createHttpServer时，服务器不会自动启动。目前，您正在传递true作为最后一个参数，也就是说应该自动启动。此配置已经是默认配置。因此，它主要用于将值设置为false，意思是不要自动启动。因此，将该值设置为false。

现在服务器不是自动启动的，我们可以配置它。setMaxResponseHeader的特定配置是NetworkListener上的配置。你可以从HttpServer那里得到它。

final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(...);
final NetworkListener listener = server.getListener("grizzly");
listener.setMaxResponseHeaders(300);
server.start();

现在，我们在配置之后手动启动服务器。有一件事我不确定是否有更好的方法让听众。我只是对"grizzly"进行了硬编码，因为我之前所做的只是遍历server.getListeners()并打印出所有的名称，并且看到"grizzly"是唯一可用的。所以这就是我以前测试过的。

除了NetworkListener配置之外，还可以通过ServerConfiguration进行其他与服务器相关的配置。您可以使用server.getServerConfiguration()获得
