二、项目开始

搭建一个简单的springboot项目

1、pom文件

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <version>2.1.3.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>2.1.3.RELEASE</version>
    </dependency>

    <!-- nacos服务注册与发现 -->
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        <version>2.1.3.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-actuator -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
        <version>2.7.2</version>
    </dependency>
    <!-- openfeign 远程调用 -->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-openfeign</artifactId>
    </dependency>
</dependencies>

2、application.yml

server:
  port: 8800

#暴露actuator端点   http://localhost:8800/actuator/sentinel
management:
  endpoints:
    web:
      exposure:
        include: '*'

spring:
  application:
    name: chenys-sentinel
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
    sentinel:
      transport:
        # 添加sentinel的控制台地址
        dashboard: 127.0.0.1:8086
        port: 8719
      eager: true
feign:
  sentinel:
    enabled: true # 激活Sentinel对Feign的支持

3、controler代码

@RestController
public class TestController {


    @GetMapping(value = "/test")
    @SentinelResource(value="test")
    public String test(){

        return "test";
    }
}

4、配置流控规则

进入sentinel 点击流控规则进行配置

5、测试

快速双击访问，出现如下结果，表示测试成功
