问题排查
1. 通过yml文件进入defaultZone参数作用类为EurekaClientConfigBean类的serviceUrl变量
2. Alt+F7搜索使用该参数的地方
3. 设置断点debug启动，getEurekaServerServiceUrls方法将集群节点以逗号进行分割组成list返回
4. 调用链往前推，最终在PeerEurekaNodes类resolvePeerUrls方法上找到过滤节点的代码
5. 循环调用isThisMyUrl方法进行过滤，方法较为简单，hostFromUrl方法获取主机名，可以看到，如果使用localhost作为defaultZone参数，则这里 hostName.equals(myInfoComparator) 参数比较就会返回true从而过滤全部以localhost配置的节点
6. 综上问题已经确定，通过设置 myUrl 参数使 isThisMyUrl 方法返回 false 即可跳过下面的判断
7. myUrl 参数由eureka.server.myUrl提供

测试

配置文件增加 my-url 参数

概述在微服务架构中，熔断与降级是保证系统稳定性的重要机制，能有效防止故障蔓延或雪崩效应。当某个服务出现异常、延迟过高或错误率过高时，触发熔断保护，将该服务“隔离”一段时间，避免影响整体系统的吞吐和可用性。SpringCloudAlibabaSentinel提供了灵活的熔断降级（Degrade）机制，可以根据响应时间（RT）、异常比例或异常数等指标，自动触发熔断并执行相应的降级策略，为业务提供及时的
