Question

Spring JPA存储库查询返回null，但如果我在数据库上运行相同的查询，则返回结果。我无法找到jpa查询返回null的原因。

存储库类：

public interface RelatorioContribuinteInadimplenteRepository extends  JpaRepository<RelatorioContribuinteInadimplenteView, String>{

  @Transactional(readOnly = true, timeout = 600)
  @Query(value = " SELECT EMPLOYEE_FORM_ID"
        + " FROM EMPLOYEE_FORM"
        + " WHERE FORM_TYPE_CD = ?1 ", nativeQuery = true)

List<RelatorioContribuinteInadimplenteView> findByFilters(String code);

  }

实体类：

  @Entity
  @Table(name = "EMPLOYEE_FORM")
  public class RelatorioContribuinteInadimplenteView implements Serializable         {
   private static final long serialVersionUID = 1L;

   @Column(name = "FORM_TYPE_CD")
   @Getter @Setter
   private String regiaoTributaria;

   @Id
    @Column(name = "EMPLOYEE_FORM_ID")
    @Getter @Setter
   private String ordem;



  }

数据库中的表格是：

 CREATE TABLE EMPLOYEE_FORM 
   (    "EMPLOYEE_FORM_ID" CHAR(12 BYTE) NOT NULL ENABLE, 
      "FORM_TYPE_CD" CHAR(12 BYTE) DEFAULT ' ' NOT NULL ENABLE, 
       PRIMARY KEY ("TAX_FORM_ID")
       );

问题是您只找到一列SELECT EMPLOYEE_FORM_ID，但尝试填写整个实体RelatorioContribuinteInadimplenteView，然后框架会丢失，因为它不知道如何填充您的实体。

使用此：SELECT * FROM ...
