java - 在 Jersey 2.22.2 中获取客户端 ip

Question

我正在尝试访问调用我的其余服务器的客户端 IP，但我只得到 null 作为响应。网络服务器正在运行，我可以从网络浏览器访问它。

我试过

@Context HttpServletRequest

还有

@Context ContainerRequest request
request.getRequestHeader("HTTP_FORWARDED")
//HTTP_X_FORWARDED
//HTTP_CLIENT_IP

但都没有成功，响应为空或空白。

设置

• Jersey v: 2.22.2
• 灰熊 v:2.3.22
• Java 5:8

Answer 1

HttpServletRequest 提供了一个应该返回远程 IP 地址的 getRemoteAddr() 方法。 请注意，代理或 NATing 可能会修改 IP 地址。

编辑:

解决方案是注入(inject)灰熊请求:

@GET
@Path("/test/")
@Produces(MediaType.APPLICATION_JSON)
public TestAddress test(@Context org.glassfish.grizzly.http.server.Request re) {
    System.out.println(re.getRemoteAddr());
    ...
}

这对我有用，但它完全依赖灰熊。
