Intellj警告没有配置工件

Question

我有两个班级

    package com.example;

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

@SpringBootApplication
public class DemoApplication {

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

    package com.example;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class SampleController {

    @RequestMapping("/")
    public String index() {
        return "Greetings from Spring Boot!";
    }

}

我想创建一个使用maven和tomcat的springboot应用程序。我想在localhost页面看到输出。

我使用8282端口，当我点击运行时，它会打开该页面，但它是空的。

所以我创造了一个战争神器。网络应用程序爆炸但这次它说不能创建工件，它不会打开该网页。

为什么显示空白页面？我在集成tomcat之前看到了输出。

这是输出

警告没有配置工件 从左边选择Artifacts，选择Web Application：Exploded（JAR是默认的？），然后警告消失，仅供参考，
