我正在实现springcloud配置,但是客户端没有自动获取配置。。。当我启动时,我的客户机正确地从服务器获取数据,但是再也没有检索到它。
这是我的cloudconfig服务器。
@EnableDiscoveryClient
@EnableConfigServer
@SpringBootApplication
public class CloudConfigApplication {
public static void main(String[] args) {
SpringApplication.run(CloudConfigApplication.class, args);
}
}
应用程序.yml

如果你想要你的配置被刷新,你必须使用@refreshscopespring doc,因为你调用@scheduled,所以这个配置不会被magic自己更新。
但根据您在配置组件中获取值的方式,它们可能会受到限制,@refreshscope将无法在refreshscope中工作
我建议在@configurationproperties中创建一个bean,并用@refreshscope进行注解,当您从执行器端点/refresh点击时,一切都应该更新,或者@schedule的组合可能会实现您想要的
