Java Jersey筛选器ContainerRequestContext与HttpServletRequest返回空指针

我正在将

HttpServletRequest

注入

ContainerRequestFilter

。当我尝试与一起使用abort时，我得到

nullppointereException

@Provider
public class AuthorizationRequestFilter implements ContainerRequestFilter {

    @Context  HttpServletRequest httpRequest;

    @Override
    public void filter(ContainerRequestContext requestContext )
                    throws IOException {
       // String auth = requestContext.getHeaderString("authorization");
        UriInfo UriInfo = requestContext.getUriInfo();

        System.out.println(UriInfo.getPath());

        //login request 
        if (UriInfo.getPath().equals("resource/users/login")) {
            return ; 
        }

        if (httpRequest.isRequestedSessionIdValid()== true) {
             requestContext.abortWith(Response
                  .status(Response.Status.UNAUTHORIZED)               
                  .build());
        }

那么

httpRequest

是空的？如果是，如何注册？如果不是，异常指向什么或哪一行？我的意思是如何注册过滤器？注册（SomeFilter.class）；我是如何在ResourceConfig文件中执行此操作的，
