**SpringBoot + SpringCloud + Feign + Sentinel 集成实现接口限流监控**

SpringBoot版本：1.5.13.RELEASE  
  
SpringCloud版本：Edgware.SR4  
  
Sentinel[详情介绍][Link 1]版本：0.1.2.RELEASE 是集成了[spring-cloud-alibaba][]

[注册中心-eureka][-eureka]  
  
[服务提供-producer][-producer]  
  
[服务消费-consumer][-consumer]  
  
[Sentinel Dashbord][]

Demo使用说明：

1.  Dashboard启动：  
    java -Dserver.port=8080 -jar sentinel-dashboard.jar  
    [官网参考][Link 2]
2.  启动erueka --> 启动Producer --> 启动Consumer
3.  展示图片:  
    \[外链图片转存失败(img-nHZ3Jf9h-1564655959756)([https://github.com/Xlinlin/SpringCloud-Demo/blob/master/SpringCloud-Sentinel/img/sentinel-dashbord-producer.png][https_github.com_Xlinlin_SpringCloud-Demo_blob_master_SpringCloud-Sentinel_img_sentinel-dashbord-producer.png])\]  
    \[外链图片转存失败(img-HTUtBRua-1564655959762)([https://github.com/Xlinlin/SpringCloud-Demo/blob/master/SpringCloud-Sentinel/img/sentinel-dashbord-consumer.png][https_github.com_Xlinlin_SpringCloud-Demo_blob_master_SpringCloud-Sentinel_img_sentinel-dashbord-consumer.png])\]

简要配置说明：

1.  dashboard启动后，客户端接入：  
    
    
        properties配置：
         # Sentinel dashbord 数据交互端口，注意单机多服务部署端口冲突
         spring.cloud.sentinel.transport.port=8729
         # sentinel  dashbord地址
         spring.cloud.sentinel.transport.dashboard=192.168.206.212:8880
         
         pom文件引入(自动引入相关依赖包)：
         <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-alibaba-sentinel</artifactId>
             <version>0.1.2.RELEASE</version>
         </dependency>
2.  producer和consumer使用sentinel仅引入 上一步中的**pom**文件即可
3.  feign的支持：
    
        pom引入：
         <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-openfeign</artifactId>
             <version>1.4.7.RELEASE</version>
         </dependency>
        
         开启sentinel支持
         # 使用阿里 sentinel监控
         feign.sentinel.enabled=true

重要提示：

1.  Sentinel版本要与springboot和springcloud大版本一致，否则会出现不可预见的异常
2.  接入到dashbord后，要请求下url，然后稍等等个1分钟左右才能到控制台，不要着急
