spring – java.lang.IllegalStateException：ApplicationEven

导读：我正在尝试创建一个Spring Boot项目. pom.xml中： SpringBootExample.java： import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication public class SpringBootExa

我正在尝试创建一个Spring Boot项目.

pom.xml中：



SpringBootExample.java：




import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication 
public class SpringBootExample {

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



当尝试将上述类作为Java应用程序执行时,我收到错误：

最佳答案
尝试添加：

        

或者,如果你已经有它评论这个(在这种情况下我使用intellij调试按钮配置)这个项目准确(GitHub petClinicSpringBoot)
