问题描述：

顺着按视频走的时候一切正常，一直看到 9.1 配置了 filter 之后发现不能通过 zuul 访问 product 的 list 接口。然后回退到 8.2，删除掉项目里的 filter 文件夹。然后还是无法访问，报错如截图所示。

当通过 zuul 9000 端口访问 product 的 list 接口时（http://localhost:9000/product/product/list），api-gateway 控制台报错：
2019-08-04 23:40:29.915 WARN 70333 — [nio-9000-exec-2] o.s.c.n.z.filters.post.SendErrorFilter : Error during filtering

com.netflix.zuul.exception.ZuulException: Forwarding error
at

其他补充点：

pom 文件核对过版本，是跟视频里一致的。

调用接口超时了，直接在浏览器里访问接口，看看耗时多少。是不是只有第一次会这样？解决方法是要配置超时时间，后面有讲。

玄。。。不过你这个启动顺序非常正确。
