线程“主”中的异常java.lang.IllegalArgumentException:找不到类

标签: java spring-boot

我正在尝试运行基本的SpringBoot应用程序。我在这里提供主类代码-

@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {


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

我的pom文件是-

运行代码时,控制台中的错误是-

我尝试在pom.xml中将依赖项用于自动配置,还尝试了@EnableAutoConfiguration,代码无法正常工作。

任何解决此问题的帮助将不胜感激。谢谢。
