我导入了一个springcloud演示，版本Finchley.SR2，启动应用程序后，我无法访问尤里卡注册中心页面，状态404。我还没有和控制器，只有一个@SpringBootApplication日食和想法的相同问题
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
如果我使用带有依赖球衣捆绑包 1.19 的 Finchley.SR1 版本，则一切正常。这是绒球.xml

这是我的应用程序.yml：
server:
port: 8761
eureka:
client:
register-with-eureka: false
fetch-registry: false
这是我的应用程序类：
@SpringBootApplication
@EnableEurekaServer
public class HubRegisterCenterApplication {
public static void main(String[] args) {
SpringApplication.run(HubRegisterCenterApplication.class, args);
}
}
问题解决了。使用mvn安装命令，我发现maven依赖jar文件存在一些问题。删除它们并重新下载，问题解决了
使用 application.properties file 而不是 application.yml 文件。喜欢
spring.application.name=cart-service
server.port=8082
它对我有用。
