1、下载 安装:java -jar sentinel-dashboard-1.7.2.jar 启动Sentinel 访问:localhost:8080 进入Sentinel 控制台
2、创建 cloundalibaba-sentinel-service8014
编写pom.xml
<dependencies> <dependency> <groupId>com.alibaba.csp</groupId> <artifactId>sentinel-datasource-nacos</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency> <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> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <dependency> <groupId>com.atguigu.springcloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>${project.version}</version> </dependency> </dependencies>
编写application.yml 配置文件
spring: application: name: cloudalibaba-sentinel-service cloud: nacos: discovery: server-addr: 8.129.215.115:8848 sentinel: transport: port: 8720 dashboard: localhost:8080 server: port: 8401 feign: sentinel: enabled: true management: endpoints: web: exposure: include: "*"
编写主启动类
@SpringBootApplication @EnableDiscoveryClient public class SentinelApplication8401 { public static void main(String[] args) { SpringApplication.run(SentinelApplication8401.class, args); } }
编写业务类
@RestController public class SentinelController { @GetMapping(value = "testA") public String testA () { return "++++++++++++testA"; } @GetMapping(value = "testB") public String testB () { return "++++++++++++testB"; } }
2、Sentinel 的 QPS 快速失败,默认报:Blocked by Sentinel (flow limiting)
