Spring Cloud Alibaba Sentinel入门简单使用

导入依赖

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-actuator</artifactId>
        </dependency>

actuator是数据采集工具采集后交给sentinel做流量控制

编写配置文件

开放所有服务端口同时告诉Sentinel nacos的服务端口

spring:
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
    sentinel:
      transport:
        dashboard: localhost:8080
  application:
    name: provider
server:
  port: 8082

management:
  endpoints:
    web:
      exposure:
        include: '*'
