Springブートアプリケーションを起動できませんか？

私はまだSpring Bootの初心者ですが、Spring Data JPAの使い方を学びたいと思っています。コントローラからクエリパラメータを取得し、そのデータをSpring Data JPAを使用してMySQLデータベースに追加しようとしました。しかし、私はこの奇妙なエラーが発生していると私はそれを修正する方法を知らない。Springブートアプリケーションを起動できませんか？

これはこれまで私が試したことです。

Home Controller 
package com.example.demo; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.PathVariable; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestParam; 
import org.springframework.web.bind.annotation.RestController; 

import com.example.demo.model.Home; 
import com.example.demo.service.HomeServiceImpl; 

@RestController 
public class HomeController { 

    @Autowired 
    private HomeServiceImpl sh; 

    @RequestMapping("/homedata") 
    public Home Hello(@RequestParam("name") String name){ 
     Home s = sh.fetchinfo(name); 

     System.out.println("sss"+s); 
     return s; 
    } 


} 

package com.example.demo; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.autoconfigure.domain.EntityScan; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.data.jpa.repository.config.EnableJpaRepositories; 
import org.springframework.transaction.annotation.EnableTransactionManagement; 

@SpringBootApplication 
@EnableAutoConfiguration 
@ComponentScan(basePackages="com.example.demo") 
@EnableJpaRepositories(basePackages="com.example.demo") 
@EnableTransactionManagement 
@EntityScan(basePackages="com.example.demo") 
public class SpringUnitTestApplication { 

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

Model class 

package com.example.demo.model; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.Table; 

@Entity 
@Table(name = "personal") 
public class Home { 


    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    @Column(name = "id") 
    private int id; 
    @Column(name = "name") 
    private String name; 



    public Home(String name) { 
     this.name = name; 

     // TODO Auto-generated constructor stub 
    } 
    public String getName() { 
     return name; 
    } 

    public String toString(){ 
     return "Hello" + getName(); 
    } 



} 


Service layer 


package com.example.demo.service; 

    import com.example.demo.model.Home; 

    public interface HomeService { 
     public Home fetchinfo(String name); 


    } 

package com.example.demo.service; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Component; 

import com.example.demo.model.Home; 
import com.example.demo.repository.HomeRepository; 

@Component 
public class HomeServiceImpl implements HomeService{ 

    @Autowired 
    private HomeRepository rs; 

    @Override 
    public Home fetchinfo(String name){ 
     Home s = new Home(name); 
     rs.save(s) ; 
     System.out.println("This is from service layer"+s); 
     return s; 
    } 



}

リポジトリ

package com.example.demo.repository; 

import java.util.List; 

import org.springframework.data.jpa.repository.JpaRepository; 
import org.springframework.data.jpa.repository.Modifying; 
import org.springframework.data.repository.CrudRepository;

は、あなたのSpringUnitTestApplicationクラスから@SpringBootApplication以外のすべての注釈を削除します。それからあなたのシナリオを教えてください。 – Zenith

@Zenithは： - *************************** アプリケーションを削除した後は********* の起動に失敗しました****************** 説明：com.example.demo.service.HomeServiceImplでフィールドRSはcom.example.demo.repository」タイプの豆を必要としました。 HomeRepository 'が見つかりませんでした。アクション：設定で 'com.example.demo.repository.HomeRepository'タイプのBeanを定義することを検討してください。 –

ここに示すコード例に従ってください：https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-data-jpa – Zenith

あなたはバージョンを混合し、データのブート・スターターで引っ張っていませんjpa。

このブログ記事では、これを行う方法と理由について詳しく説明しています。 https://spring.io/blog/2016/04/13/overriding-dependency-versions-with-spring-boot

あなたが唯一の次の依存関係を宣言する必要がある必要があり、
