我在控制面板的"系统"中找到了环境变量,并创建了两个新变量,一个用于用户变量,另一个用于系统变量.两者都被命名为JAVA_HOME,两者都指向

C:\太阳\ SDK\JDK\BIN

但由于某种原因,我在运行Java命令时仍会遇到以下错误...

BUILD FAILED

package hello;

import org.springframework.boot.SpringApplication;

@SpringBootApplication
public class Application {

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

这是我的GreeetingController.java班级:
