在 localhost 中打開 eureka 頁面時出現 404 錯誤

Question

我已經使用 gradle 從 intellij 啟動了我的Eureka Server ，並且服務器已按照日志啟動並運行。 但是通過使用以下 url 在瀏覽器中出現404錯誤

http://localhost:8761/eureka/

請從 intellij 控制台找到日志

application.properties 文件。

server.port=8761

#telling the server not to register himself in the service
eureka.client.register-with-eureka=false

#Eureka clients fetch the service registry (ServiceInstance : (URL, PORT, HOST)) from the Eureka server
eureka.client.fetch-registry=false

Answer 1

我的設置就是這樣並且工作正常：

應用.java

@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {

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

}

應用程序.yml

server:
  port: 8761

management:
  endpoints:
    web:
      exposure:
        include: '*'

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false

Answer 2

嘗試在主 class 中添加@EnableEurekaServer 。

嘗試點擊 url：

http://localhost:8761/

代替

http://localhost:8761/eureka/
