java - 无法找到或加载主类BasicApp.Application

Question

我是 Spring Boot 新手，正在尝试在 Spring Boot 上创建一个非常基本的应用程序。但是，我在创建应用程序时遇到此错误。

Could not find or load main class BasicApp.Application

我的应用程序有两个类，一个是 Controller 类，一个是 Main 类。这是我的代码:

Application.java

package BasicApp;

import org.springframework.boot.SpringApplication;

public class Application
{
    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);
    }
}

MainController.java

package BasicApp;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@EnableAutoConfiguration
public class MainController 
{
    @RequestMapping("/send")
    @ResponseBody
    public String sendMessage()
    {
        return("M sending message");
    }
}

有人可以帮我解决这个错误吗？

将@SpringBootApplication注释添加到您的Application类中，它将为您完成所有配置。
