1、添加依赖

		<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-sentinel</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><dependency><groupId>com.alibaba.csp</groupId><artifactId>sentinel-web-servlet</artifactId></dependency>

2、下载sentinel dashboard

首先，查看spring-cloud-starter-alibaba-sentinel依赖添加的sentinel-core的版本号

可以看到sentinel-core的版本号是1.7.1，所以 sentinel dashboard的版本号也要是1.7.1，所以本案例下载 1.7.1的dashboard
