私はSpring MVC + Spring-data-jpa + querydslを開発しています。 querydslのコードを作成するとき(そのコードが正常に機能する前)、querydsl関連のコードを追加すると、何が問題になっているのかわからない次のエラーが発生し始めました。ご案内ください。
参考のためのエラー:

わかりました、私はこれに対する解決策を得ました。テーブル名は使用しないでください。常にモデル/エンティティ名である必要があります。これ(@Query( "SELECT v FROM Visit v WHERE v.visitType = 'NEW'"))は問題を解決します。
@Repository
public interface VisitRepository extends JpaRepository<Visit, Integer>,
QueryDslPredicateExecutor<Visit>{
List<Visit> findByVisitType(String visitType);
@Query("SELECT v FROM Visit v WHERE v.visitType='NEW'")
List<Visit> findByVisitType();
}
私は非常によく似た問題を抱えていました。私の質問は:
select fa from FlexAllowanceSnapshot s where s.employeeId=:employeeId
、あるべきだった:
select fa from FlexAllowanceSnapshot fa where fa.employeeId=:employeeId
SQLではなくHQLであることに注意する必要があるため、構文とルールは少し異なります。
hibernate.cfg.xmlファイルには、以下のようなテーブルのマッピングが含まれている必要があります。ファイルにないか確認してください。
......
<hibernate-configuration>
......
......
<session-factory>
......
<mapping class="com.test.bean.dbBean.testTableHibernate"/>
......
</session-factory>
</hibernate-configuration>
.....
上記の方法を試してもエラーが発生する場合は、これを試すことができます(これで問題は解決しました)
@Query(value = "normal Sql query", nativeQuery=true).
値とnativeQueryを指定します
