我刚刚从spring初始值设定项创建了spring启动应用程序，并在intellij中执行它。但我面临着一些错误。有人能帮我解决这个错误吗？
package com.demo.grocery;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class GroceryApplication {
public static void main(String[] args) {
SpringApplication.run(GroceryApplication.class, args);
}
}
这就是我面对的错误
