Dashboard監控頁面和Zuul路由閘道器

Dashboard監控頁面

dashboard監控功能：我們需要前端頁面能夠監控提供者provider8001的工作狀態

對dashboard監控頁面的介紹：

1.在使用者端導依賴

3.主啟動類開啟支援註解

4.在provider8001也要確儲存在它能被監控的依賴actuator

5.在provider8001要增加一個可以供前端存取的servlet，同時入到springboot容器中

6.測試

可以先存取8001埠下面的方法看看能不能調到底層資料，可以再

存取：http://localhost:9001/hystrix 出現下面頁面

我們每重新整理一次，監控頁面就有更新

Zuul路由閘道器

目的：為了安全，將前端url存取時真實的ip替換成其他

zuul的使用要注入到eureka中，需要有組態檔，組態檔被spring boot託管
