注意版本问题

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

复制代码

<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。

复制代码

defaultFallback 这是熔断后的方法名称
