zuul（路由网关）与 Hystrix Dasboard 监控平台搭建

基于  eureka 服务于发现 （集群模式）  添加内容

1..... zuul   路由网关   

　　zuul  核心就是过滤器  通过过滤器 实现请求过滤  身份校验等

　　过滤：         对请求的处理过程进行干预

　　请求路由： 将外部请求转发到具体微服务实例上

2.....Zuul 过滤展示   -----------自定义过滤器   ----


​ 　　 继承ZuulFilter ZuulFilter是一个抽象类 需要覆盖它的四个方法

4.....  Hystrix  Dasboard 监控平台搭建

　　　　Hystrix 还提供了准时的调用监控（Hystrix Dashboard) Hystrix会持续的记录所有的通过Hystrix的请求进行的信息，并以统计报表和图形的形式展示给用户看 包含执行了多少次的请求 多少次成功和失败

​　　　　　　 Netflix 通过Hystrix-metrics-event-stream 项目实现了 对以上指标的监控 springCloud 也提供了Hystrix Dashboard 的整合 对监控内容转换成可视化界面
