我从start.spring.io下载了一个配置项目。添加了@EnableConfigServer添加了3-4个属性git、应用程序名称和端口，但是在启动服务器时还没有开始。我尝试了3种不同的弹簧引导版本，无论哪里我都会出错。我们能做些什么？

这是pom.xml

          </plugin>
        </plugins>
      </build>
    
    </project>

应用程序控制代码：

package com.photoapp;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.config.server.EnableConfigServer;
    @EnableConfigServer  
    @SpringBootApplication  
    public class ConfigServerApplication   
    {   
        public static void main(String[] args) {    
            SpringApplication.run(ConfigServerApplication.class, args);
                
        }
    
    }

Application.properties

server.port=8012  
spring.application.name=ConfigServer  
#spring.profiles.active=native  
spring.cloud.config.server.git.uri=https://github.com/SubhankarMukherjee/PhotoAppConfiguration.git  
spring.cloud.config.server.git.username = ****  
spring.cloud.config.server.git.password = ****

我得贝罗错误了。尝试了所有可能的组合，但根本不起作用

看起来您的pom.xml中缺少了一个依赖项，尝试添加：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-commons</artifactId>
    <version>${spring-cloud.version}</version>
</dependency>
