如何在Jersey 2.25.1应用程序中获取呼叫者的IP地址？

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Context;

@Path("/example")
public class ExampleResource {

    @GET
    public String getCallerIP(@Context HttpServletRequest request) {
        String callerIP = request.getRemoteAddr();
        return "Caller IP: " + callerIP;
    }
}

import javax.ws.rs.GET;
import javax.ws.rs.HeaderParam;
import javax.ws.rs.Path;

@Path("/example")
public class ExampleResource {

    @GET
    public String getCallerIP(@HeaderParam("X-Forwarded-For") String callerIP) {
        return "Caller IP: " + callerIP;
    }
}
