灰熊+泽西岛仅在Localhost上收听 [英] Grizzly + Jersey Listening ONLY on Localhost

问题描述

我正在使用带有Grizzly嵌入式版本的Jersey，我只想在本地主机上绑定/监听.我正在使用带有create调用的GrizzlyWebContainerFactory创建ThreadSelector:

I'm using Jersey with an embedded version of Grizzly and I'd like to bind/listen on localhost ONLY. I'm creating the ThreadSelector using the GrizzlyWebContainerFactory with the create call:

threadSelector = GrizzlyWebContainerFactory.create("http://127.0.0.1:8080/", initParams);

这可行，但是我仍然可以从外部计算机上访问服务器.我如何才能将其绑定到/仅在本地主机上监听?

This works, but I'm still able to hit the server from an external machine. How can I get it to bind to/listen on ONLY localhost?

这是用于配置的东西，所以我不希望有任何其他东西能够连接到该服务器.

This is for configuration stuff, so I don't want anything off box to be able to connect to this server.

推荐答案

我能够使用泽西2.3.1中带有嵌入式版本Grizzly的主机名localhost来做到这一点:

I was able to do this using the hostname localhost in Jersey 2.3.1 with an embedded version of Grizzly:

import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
// ...
GrizzlyHttpServerFactory.createHttpServer(
    URI.create("http://localhost:9580/my-app/")
);

测试结果为:

> curl -I http://myhost.com:9580/my-app
curl: (7) couldn't connect to host

当使用URI "http://0.0.0.0:9580/my-app/"或"http://myhost.com:9580/my-app/"启动Grizzly服务器时，我可以使用

Whereas when starting the Grizzly server with the URIs "http://0.0.0.0:9580/my-app/", or "http://myhost.com:9580/my-app/" I am be able to hit it with

> curl -I http://myhost.com:9580/my-app
HTTP/1.1 200 Not Found
...

这是一张表格，其中列出了使用GrizzlyHttpServerFactory时哪些主机使用哪些URL.据我所知，这里没有什么惊奇之处:

Here's a table of which hosts work with which URLs when using GrizzlyHttpServerFactory. No surprises here, as far as I understand:

# For http://0.0.0.0:9575/my-app      | Works?
curl -I http://0.0.0.0:9575/my-app    | Yes
curl -I http://127.0.0.1:9575/my-app  | Yes
curl -I http://localhost:9575/my-app  | Yes
curl -I http://myhost.com:9575/my-app | Yes
                                      | 
# For http://127.0.0.1:9575/my-app    | 
# For http://localhost:9575/my-app    |
curl -I http://0.0.0.0:9575/my-app    | Yes
curl -I http://127.0.0.1:9575/my-app  | Yes
curl -I http://localhost:9575/my-app  | Yes
curl -I http://myhost.com:9575/my-app | No
                                      | 
# For http://myhost.com:9585/my-app   | 
curl -I http://0.0.0.0:9585/my-app    | No
curl -I http://127.0.0.1:9585/my-app  | No
curl -I http://localhost:9575/my-app  | No
curl -I http://myhost.com:9585/my-app | Yes
