无法初始化 Eureka servlet 上下文 pom.xmlapplication.ymlshared/discovery-service.ymlpom.xml主要网关发现配置

如何解决无法初始化 Eureka servlet 上下文 pom.xmlapplication.ymlshared/discovery-service.ymlpom.xml主要网关发现配置

我正在将我的实际项目升级到 Spring Boot 2.5.2。 我有一个配置服务器、一个 zuul 网关和一个发现服务器。 现在我看到 Spring Cloud 在我的发现服务器中有一个嵌入式网关，我想使用它。所以我最后只有配置服务器和发现服务器（包括我的网关） 但我从发现服务器获得以下堆栈跟踪：

这是我的代码：

主要

@SpringBootApplication
@EnableEurekaServer
public class discoveryServiceApplication {

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

}

网关发现配置

@Configuration
@EnablediscoveryClient
public class GatewaydiscoveryConfiguration {

    @Bean
    public discoveryClientRouteDeFinitionLocator
            discoveryClientRouteLocator(ReactivediscoveryClient discoveryClient,discoveryLocatorProperties locatorProperties) {

        return new discoveryClientRouteDeFinitionLocator(discoveryClient,locatorProperties);
    }
}

如果有人能帮助我，我将不胜感激。

提前致谢！
