annot execute request on any known server

在启动Spring Cloud微服务提供者时,如果出现异常信息"Cannot execute request on any known server",有几个可能的原因。首先,可能是因为在默认设置下,Eureka服务注册中心会将自己作为客户端来尝试注册自己,所以我们需要禁用它的客户端注册。可以通过配置"registerWithEureka"和"fetchRegistry"来实现禁用。[1]另外,如果是客户端报错,可能是因为Eureka没有启动、配置的defaultZone地址错误,或者在使用安全验证时需要进行csrf验证。可以通过在客户端配置正确的Eureka地址或者在服务端配置禁用csrf验证的代码来解决这个问题。[2]具体的配置可以参考官方文档或者使用驼峰原则将下划线后面的字母改为小写来配置。[3]
