如何从ContainerRequestContext JERSEY 2.1获取IP？ [英] How to get IP from ContainerRequestContext JERSEY 2.1?

问题描述

我的代码是这样的：

public void filter(ContainerRequestContext request) throws IOException 
  {
   // can I get Ip from request?????

 }

如何从请求？

推荐答案

根据这个 JIRA 票据，基于此讨论，他们添加了对将 HttpServletRequest 注入过滤器的支持，上面的JIRA看起来是一段代码片段像这样：

According to this JIRA ticket, based on this discussion, they added support for injecting the HttpServletRequest into your filter, a code snippet from the above JIRA looks like this:

public class MyRequestFilter implements ContainerRequestFilter {

  @Context
  private HttpServletRequest servletRequest;

然后您可以使用 HttpServletRequest API来获取远程IP，请参阅完整的 Javadoc ，摘录：

You can then use the HttpServletRequest API to get the Remote IP, see the full Javadoc here, excerpt:

getRemoteAddr

getRemoteAddr

java.lang.String getRemoteAddr（）

java.lang.String getRemoteAddr()

返回发送请求的客户端或最后一个代理的Internet协议（IP）地址。对于HTTP servlet，与CGI变量REMOTE_ADDR的值相同。

Returns the Internet Protocol (IP) address of the client or last proxy that sent the request. For HTTP servlets, same as the value of the CGI variable REMOTE_ADDR.

返回：

包含发送请求的客户端的IP地址

a String containing the IP address of the client that sent the request
