@Convert不适用于Hibernate和QueryDSL
我有一个表Incidencia CHAR（1字节）列visiblemovil 。 此列有2个可能的值：我想使用@Convert注释转换为boolean值的“S”或“N”（是/否，西班牙语是si / no）。 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）时出现此错误：
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;
}
}

我究竟做错了什么？
谢谢。
您将映射注释放置在实体类中映射字段的getter上。 根据规范的2.3.1章节，这导致了基于财产的访问。
该规范规定，只有getter应该注解映射。 但是这对@Convert注释来说可能还不够？
你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。）
你的转换器看起来正确 唯一的东西是映射中的@Basic注释。 根据定义，@ @Basic告诉一个属性将被持久化并且将使用一个标准映射，所以这可能是一个问题（另外我没有看到在你的情况下混合@Basic和@Column强烈理由）。
@Column(name = "VISIBLE")
@Convert(converter = SiNoToBooleanConverter.class)
public Boolean getVisible() {
return visiblemovil;
}
注意：我没有测试过，但应该解决问题。 值得尝试将注释移动到现场，而不是吸气剂。
尝试下面的代码片段，如果其中一个工作，你可以实现目标，而无需使用任何converter或@convert ：
Expression<String> expr = new CaseBuilder()
.when(incidencia.getVisible()).then("S")
.otherwise("N");
query().from(incidencia).list(incidencia.visible.when(true).then("S").otherwise("N"));
