Question

尝试配置我的eureka注册表，一切似乎正常，该应用程序启动并显示有关其实例的信息。我面临的问题是，它一直在注册错误的网址作为其节点。特别是，它一直在路径中添加/eureka后缀。

这是我的pom（非常标准）：

</project>

这是主要课程：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class RegistryApplication {

    public static void main(String[] args) {
        SpringApplication.run(RegistryApplication.class, args);
    }
}

最后，我的应用程序属性：

server:
  port: 8761
spring:
  application:
    name: project-registry
eureka:
  client:
    fetchRegistry: false
    registerWithEureka: false

如启动日志所示，它在http://localhost:8761/eureka/处注册了自己，这是不正确的，因为仪表板显示在http://localhost:8761上。

配置中缺少什么？

Answer 1

首先，您将 defaultZone 留在了配置文件中，它应该是：

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

其中一部分，一件事就是显示仪表板的URL，其中没有“ / eureka”：

http://localhost:8761

另一件事是在哪里注册了服务，即“ / eureka”

http://localhost:8761/eureka

为什么尤里卡用错误的URL注册自己？
