为什么我的zuul配置的拦截器没有生效？

Question

public class LoginFilter extends ZuulFilter {

    @Override // 过滤器的类型 pre route post error
    public String filterType() {
        return "pre";
    }

    @Override // 执行顺序，返回值越小，优先级越高，为防止以后有更优先的过滤器，可以先写10
    public int filterOrder() {
        return 0;
    }

    @Override // 是否执行该过滤器
    public boolean shouldFilter() {
        return true;
    }

    @Override // 编写过滤器的业务逻辑
    public Object run() throws ZuulException {
        // 初始化context上下文对象， 不像以前的 servlet spring
        RequestContext context = RequestContext.getCurrentContext();
        // 获取request对象
        HttpServletRequest request = context.getRequest();
        // 获取参数
        String token = request.getParameter("token");
        System.out.println("token="+token);
        if(StringUtils.isBlank(token)){
            // 为空，拦截，不转发请求
            context.setSendZuulResponse(false);
            // 返回状态 成功/失败
            context.setResponseStatusCode(401);

            // 设置响应提示
            context.setResponseBody("requset error!");

        }

        return null; // 返回值为null，代表该过滤器什么都不做
    }
}
