我无法查看 Eureka 仪表板

Question

当我访问 http://localhost:8761/ 或 http://localhost:8761/eureka 时，我收到“Whitelabel Error Page”。

我的应用程序类：

    @SpringBootApplication
    @EnableEurekaServer
    public class DiscoveryServerApplication {
        public static void main(String[] args) {
            SpringApplication.run(DiscoveryServerApplication.class, args);
        }
    }

应用程序属性：

eureka.instance.hostname=localhost
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
server.port=8761
spring.freemarker.template-loader-path=classpath:/templates/
spring.freemarker.prefer-file-system-access=false

发现服务器模块中的

    <dependency>

我做错了什么？

PS：我使用的是Spring Boot 3.1.3

Answer 1

问题出在

spring-cloud.version

。我将其更改为

<spring-cloud.version>2022.0.4</spring-cloud.version>

并且发现服务器工作了。
