Dashboard监控页面和Zuul路由网关

Dashboard监控页面

dashboard监控功能：我们需要前端页面能够监控提供者provider8001的工作状态

对dashboard监控页面的介绍：

1.在客户端导依赖

    </dependencies>
</project>

2.配置文件

3.主启动类开启支持注解

4.在provider8001也要确保存在它能被监控的依赖actuator

5.在provider8001要增加一个可以供前端访问的servlet，同时入到springboot容器中

6.测试

可以先访问8001端口下面的方法看看能不能调到底层数据，可以再

访问：http://localhost:9001/hystrix 出现下面页面

我们每刷新一次，监控页面就有更新

Zuul路由网关

目的：为了安全，将前端url访问时真实的ip替换成其他

zuul的使用要注入到eureka中，需要有配置文件，配置文件被spring boot托管

1.导包

    <dependencies>
        <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-zuul -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
