spring boot 整合 sentinel

注意版本问题

我这是jdk11 、spring boot 2.7.15 、  alibaba-sentinel  2.1.2.RELEASE

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.15</version><relativePath/> <!-- lookup parent from repository --></parent>

<!-- sentinel客户端与dashboard通信依赖 --><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-sentinel</artifactId><version>2.1.2.RELEASE</version></dependency>

# sentinel-dashboard地址
spring.cloud.sentinel.transport.dashboard=localhost:8080
spring.cloud.sentinel.transport.port=8080
spring.cloud.sentinel.eager=true
spring.main.allow-circular-references=true# 开启feign对sentinel的支持
feign.sentinel.enabled=true

@Override@SentinelResource(value = "helloAnother", blockHandler = "defaultFallback")
public String helloAnother(String name) {//xxxxxxxx
}

helloAnother 方法名写的这个   sentinel 面板上 资源名也要找到这个名称 。

defaultFallback 这是熔断后的方法名称
