Sentinel 一、安装1、下载sentinel地址：https://github.com/alibaba/Sentinel2、运行java -jar sentinel-dashboard-1.8.1.jar3、注意事项sentinel默认8080端口，需注意端口冲突的问题二、微服务整合Sentinel1、启动Nacoswindows环境或Linux环境下启动startup.cmd或startup.sh2、新建Sentinel8401模块pom<!-- API 通用pom根据自己情况而定--> <dependency> <groupId>com.sw</groupId> <artifactId>cloud-api-commons</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <!-- Nacos --> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency> <!-- sentinel --> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId> </dependency> <!-- openfign --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <!-- lombok --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency>ymlserver: port: 8401 spring: application: name: cloud-alibaba-sentinel-service cloud: nacos: discovery: server-addr: localhost:8848 sentinel: transport: # sentinel dashboard地址 dashboard: localhost:8080 # 默认8719端口，如果8719被占用，默认递增 port: 8719 management: endpoints: web: exposure: include: '*'启动类@SpringBootApplication @EnableDiscoveryClient public class MainApp8401 { public static void main(String[] args) { SpringApplication.run(MainApp8401.class, args); } } controller@Slf4j @RestController public class FlowLimitController { @GetMapping("/testa") public String testA() { return "-----testA------"; } @GetMapping("/testb") public String testB() { log.info(Thread.currentThread().getName() + "\t" + "处理了/testb请求！"); return "-----testB------"; } }3、启动测试Sentinel默认的账号密码都是sentinel因为sentinel是懒加载机制，所以需先完成一次请求，才能在sentinel控制面板看到簇点链路
