【Sentinel如何进行流量监控】这篇文件是对sentinel-dashboard自己进行监控。本篇看看如何在自己的SpringBoot项目或者SpringCloud项目接入Sentinel。具体参考：

https://github.com/alibaba/spring-cloud-alibaba/wiki/Sentinel

0x01：新建项目olive-sentinel-client

项目中的pom.xml文件引入

<dependency>
       <groupId>com.alibaba.cloud</groupId>
       <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
       <version>2.2.1.RELEASE</version>
</dependency>

0x02：application.properties配置文件添加配置项

server.port=8081
spring.application.name=olive-sentinel-client
spring.cloud.sentinel.transport.dashboard=127.0.0.1:8080

spring.cloud.sentinel.transport.dashboard配置项是配置sentinel-dashboard控制台的地址和端口；另外Sentinel还提供了其他的配置参数，具体可以参考

https://github.com/alibaba/spring-cloud-alibaba/wiki/Sentinel

0x03：编写一个Controller和SpringBoot启动类

package com.sentinel.controller;

import java.util.HashMap;
import java.util.Map;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @RequestMapping(value={"/getTest"},produces="application/json;charset=UTF-8")
    public Map<String, Object> getTest() {
        Map<String, Object> result = new HashMap<>();
        result.put("code", "success");
        return result;
    }

}

package com.sentinel;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

0x04：启动sentinel-dashboard控制台

登录sentinel-dashboard控制台，可以看到一个空的界面
