java – @Convert不适用于Hibernate和QueryDSL

我有一张表Incidencia,有一个CHAR(1 Byte)列visiblemovil.此列有两个可能的值：“S”或“N”(是/否,西班牙语为si / no)我希望使用@Convert注释转换为布尔值.这是我的代码：

转换器：

@Converter
public class SiNoToBooleanConverter implements AttributeConverter<Boolean,String> {

    @Override
    public String convertToDatabaseColumn(Boolean aBoolean) {
        return aBoolean ? "S" : "N";
    }

    @Override
    public Boolean convertToEntityAttribute(String s) {
        return "S".equals(s);
    }
}

实体：

@FilterDef(name = "PREGINCIDENCIA_FILTRO_FECHA",parameters = @ParamDef(name = "ultimaFechaSinc",type = "date"))
@Entity
public class Incidencia {

    private List<Incidenciapreguntas> preguntasList;

    private Integer codincidencia;

    private String descripcion;

    private Double horasfinalizacion;

    @Convert(converter = SiNoToBooleanConverter.class)
    private Boolean visiblemovil;

    private boolean tieneDocumentacion;

    @Id
    @Column(name = "CODINCIDENCIA")
    public Integer getCodincidencia() {
        return codincidencia;
    }

    public void setCodincidencia(Integer codincidencia) {
        this.codincidencia = codincidencia;
    }

    @Basic
    @Column(name = "DESCRIPCION")
    public String getDescripcion() {
        return descripcion;
    }

    public void setDescripcion(String descripcion) {
        this.descripcion = descripcion;
    }

    @OneToMany(mappedBy = "incidencia")
    @Filter(name = "PREGINCIDENCIA_FILTRO_FECHA",condition = "FMODIFICACION > :ultimaFechaSinc OR FMODIFICACION IS NULL")
    public List<Incidenciapreguntas> getPreguntasList() {
        return preguntasList;
    }

    public void setPreguntasList(List<Incidenciapreguntas> preguntasList) {
        this.preguntasList = preguntasList;
    }

    @Transient
    public boolean isTieneDocumentacion() {
        return tieneDocumentacion;
    }

    public void setTieneDocumentacion(boolean tieneDocumentacion) {
        this.tieneDocumentacion = tieneDocumentacion;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        Incidencia that = (Incidencia) o;

        if (codincidencia != null ? !codincidencia.equals(that.codincidencia) : that.codincidencia != null)
            return false;
        if (descripcion != null ? !descripcion.equals(that.descripcion) : that.descripcion != null) return false;
        return true;
    }

    @Override
    public int hashCode() {
        int result = codincidencia != null ? codincidencia.hashCode() : 0;
        result = 31 * result + (descripcion != null ? descripcion.hashCode() : 0);
        return result;
    }

    @Basic
    @Column(name = "HORASFINALIZACION")
    public Double getHorasfinalizacion() {
        return horasfinalizacion;
    }

    public void setHorasfinalizacion(Double horasfinalizacion) {
        this.horasfinalizacion = horasfinalizacion;
    }

//    @Basic
    @Column(name = "VISIBLEMOVIL")
    public Boolean getVisiblemovil() {
        return visiblemovil;
    }

    public void setVisiblemovil(Boolean visiblemovil) {
        this.visiblemovil = visiblemovil;
    }
}

当我执行SELECT语句(使用QueryDSL)时,我收到此错误：

org.hibernate.exception.GenericJDBCException: Fail to convert to internal representation
javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Fail to convert to internal representation

库：

@Repository
public class IncidenciasDAO extends BaseDAO {

      public List<Incidencia> getIncidencias() {
        QIncidencia qIncidencia = QIncidencia.incidencia;
        JPAQuery query = new JPAQuery(entityManager);
        List<Incidencia> incidencias = query.from(qIncidencia).list(qIncidencia);
        return incidencias;
    }
}

完整的堆栈跟踪

我究竟做错了什么？

谢谢.

解决方法

您将映射注释放在实体类中映射字段的getter上.
根据 specification的第2.3.1章,这导致了基于财产的访问.

规范声明只应为映射注释getter.但也许这对@Convert注释来说还不够？

您可以尝试注释该字段：

@Entity
public class Incidencia {

    @Column(name = "VISIBLE")
    @Convert(converter = SiNoToBooleanConverter.class)
    private Boolean visible;

    //other fields

    public Boolean getVisible() {
        return visible;
    }

    public void setVisible(Boolean visible) {
        this.visible = visible;
    }

}

(我更正了getter / setter方法中变量/字段的名称.)
