# 1.创建项目引入依赖
<!--引入nacos client依赖--><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId></dependency><!--引入sentinel依赖--><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-sentinel</artifactId></dependency>
# 2.配置
server.port=8789spring.application.name=nacosclientspring.cloud.nacos.server-addr=localhost:8848spring.cloud.nacos.discovery.server-addr=${spring.cloud.nacos.server-addr}spring.cloud.sentinel.enabled=true # 开启sentinel 默认开启spring.cloud.sentinel.transport.dashboard=localhost:9191 # 连接dashboardspring.cloud.sentinel.transport.port=8719 # 与dashboard通信的端口
# 3.启动服务
# 4.访问dashboard界面查看服务监控- 发现界面什么都没有? - 默认情况下sentiel为延迟加载,不会在启动之后立即创建服务监控,需要对服务进行调用时才会初始化
# 5.开发服务
@RestController@Slf4jpublic class SentinelController {@GetMapping("/sentinel/test")public String test(){log.info("sentinel test");return "sentinel test ";}@GetMapping("/sentinel/test1")public String test1(){log.info("sentinel test1");return "sentinel test1 ";}}
# 6.启动进行调用- http://localhost:8789/sentinel/test
# 7.查看监控界面
