私はspringbootを使ってエンティティを作成し、CrudRepositoryでCRUD関数を作成しています。私はfindServiceを使ってfindbyHoliday(String name)を作成することができます 私は本当にspringboot CrudRepository何か方向を教えてください。スプリングブートCrudRepository findby関数がマップできません

ここで私は私の

application.properties

spring.jpa.generate-ddl=true 
spring.jpa.hibernate.ddl-auto=update 
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect 
spring.jpa.hibernate.use-new-id-generator-mappings=true 
spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl 
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl 
spring.jpa.properties.hibernate.format_sql = false 
spring.jpa.properties.hibernate.default_schema=SPRINGUSER 

public interface HolidayScheduleRepository extends CrudRepository<HolidaySchedule,Long>{ 
List<HolidaySchedule> findByHDay(@Param("HDay") String hday); 

} 
HolidayScheduleRepository.java

をCrudRepositoryを拡張機能を作成しようとHERESに私のインターフェイス示さ

相続人は私のエンティティ

HolidaySchedule.java

@Entity // This tells Hibernate to make a table out of this class 
@Table(name="TWD_HSD_HOLIDAY_SCHEDULE") 
public class HolidaySchedule { 
    @Id 
    @Column(name="HSD_ID") 
    @GeneratedValue(strategy=GenerationType.AUTO) 
    private Integer Id; 
    @Column(name="HSD_DATE") 
    private String HDate; 
    @Column(name="HSD_DAY") 
    private String HDay; 
    @Column(name="HSD_HOLIDAY") 
    private String HHoliday; 

ようやく私コントローラメソッド

@Controller // This means that this class is a Controller 
@RequestMapping(path="/test") 
....... 
@GetMapping(path="crudtest") 
     @ResponseBody 
     public List<HolidaySchedule> findHolidayByName(){ 
      return holidayScheduleRepository.findByHDay("Monday"); 
     }

'のネイティブクエリは、A取りされますJPQLクエリは、デフォルトではSQLクエリではありません。 JPQLクエリの代わりにSQLクエリを記述しようとしています。また、単一の列を選択しようとしていますが、完全なオブジェクトが必要です(どちらも機能しません)。どちらの方法でもエラーが発生します。 –

これは難しいことですが、小文字(camelCase形式)ですべてのフィールド名を開始するなどの標準的なJavaの規約に従うことを強くお勧めします。私はそれがフィールドを見つけることができない理由だと信じています。

あなたはそれがリポジトリモデルで

`List<HolidaySchedule> findByHDay(String hDay);` 

@Column(name="HSD_DAY") private String hDay;

で次のようになりたいと思うでしょう。

ここから始めて、どこから得られるかを確認してください。それは作品を意志、コントローラで

public interface HolidayScheduleRepository extends CrudRepository<HolidaySchedule,Long>{ 

    @Query("SELECT hs FROM HolidaySchedule hs WHERE hs.HDay = ?1") 
    List<HolidaySchedule> findByHDay(String hday); 

} 

、@Autowired jsut、それを使用します。

はい、私も試しましたが、それも動作しますが、私はすでに多くのエンティティとデータベースを構築し、私は多くのリポジトリを@Serviceとして拡張して作成しました – user2285201

必要がない場合は、JPQLを使用する必要はありません...インターフェイスでメソッドの名前をどのように指定するかは、そのクエリを自動的に生成します。 – Chad

私は本当にこの名前を保持したい "HST_XXX"私のデータベースには、このための任意のソリューションですか? – user2285201

チャド以下

List<HolidaySchedule> findByHDay(String hDay);` 

によって提案されたように、1つの以上解決策は、ネイティブクエリが、より良いソリューションを使用することがある。この問題Query` @

public interface HolidayScheduleRepository extends CrudRepository<HolidaySchedule,Long>{ 

    @Query("SELECT * FROM TWD_HSD_HOLIDAY_SCHEDULE WHERE HSD_DAY = :hday") 
    List<HolidaySchedule> findByHDay(@Param("hday) String hday);
