私の最初のSpringbootアプリケーションが起動しません

私は単純なspringbootアプリケーションを構築しようとしています。これは私のクラスのコントローラ "HelloController.java" である：これは、返されたスタックトレースです私の最初のSpringbootアプリケーションが起動しません

package controller; 

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

@RestController 

public class HelloController { 

    @RequestMapping("/") 
    public String index() 
    { 
     return "Welcome to Spring Boot"; 
    } 

}

メインクラス "Application.java"

package hello; 

import org.joda.time.LocalTime; 
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.context.ApplicationContext; 

@SpringBootApplication 
public class Application { 
    public static void main(String[] args) { 
     Greeter greeter = new Greeter(); 
     LocalTime currentTime = new LocalTime(); 
     System.out.println(greeter.sayHello());    
     System.out.println("The current local time is: " + currentTime); 
     SpringApplication.run(Application.class, args); 

    } 
}

は動作するはずです。とにかくそこに上書きされる項目を宣言していないようです。その後、Mavenビルドは正常に動作するはずです。結果として得られるアーティファクトを展開できるはずです。
