我正在开发一个
Java EE 7应用程序(持久性提供程序是Hibernate 4.3.5,DB是Oracle 11g),其中我使用的是一个实体类,其中Long字段表示日期的毫秒数.这样做是为了避免使用DB的日期数据类型(例如时区处理)的问题.这是相关的实体类代码：
import java.util.Date;
@Table
@Entity
public class Transference implements Serializable {
private static final long serialVersionUID = 1L;
// ... elided fields
private Date dateTime;
// ... elided setters and getters
@Column(name = "datetime")
@Convert(converter = DateConverter.class)
@NotNull
public Date getDateTime() {
return dateTime;
}
}
元模型类中的属性：
public static volatile SingularAttribute<Transference, Date> dateTime;
这是简单的JPA 2.1转换器：
import java.util.Date;
@Converter
public class DateConverter implements AttributeConverter<Date, Long> {
@Override
public Long convertToDatabaseColumn(Date attribute) {
return (attribute == null)? null : attribute.getTime();
}
@Override
public Date convertToEntityAttribute(Long dbData) {
return dbData == null? null : new Date(dbData);
}
}
表定义：
CREATE TABLE transference (
-- fields ...
datetime NUMBER(20) NOT NULL,
-- constraints...
);
坚持和阅读领域价值就像一个魅力.当我尝试在CriteriaQuery中使用谓词时,问题出现了,该谓词将字段与值进行比较：
private List<Transference> queryResultList() {
CriteriaBuilder cb = this.entityManager.getCriteriaBuilder();
CriteriaQuery<Transference> cq = cb.createQuery(Transference.class);
Root<Transference> root = cq.from(Transference.class);
List<Predicate> predicates = new ArrayList<>();
// Predicates with other fields...
if (this.dateTo != null) {
Path<Date> pathDateTo = root.get(Transference_.dateTime);
Predicate predDateTo = cb.greaterThanOrEqualTo(pathDateTo, this.dateTo);
predicates.add(predDateTo);
}
Order orderBy = cb.desc(root.get(Transference_.dateTime));
Predicate[] predicatesArray = {};
cq.select(root).where(predicates.toArray(predicatesArray)).orderBy(orderBy);
TypedQuery<Transference> tq = this.getEntityManager().createQuery(cq);
return tq.getResultList(); // <- A exception is thrown here, when predDateTo is used in the query.
}
这是我得到的例外：

在条件查询谓词中使用此类字段的正确方法是什么？转换器仅适用于读取/保持.即使在JPA 2.1规范中(顺便说一下,它非常大),我一直在寻找一种方法并且无法做到.我在这里错过了什么？感谢您的关注.
最佳答案 谢谢你的回答.我无法弄清楚如何使用该字段,但我提出了这个(不那么漂亮)的解决方法：
private Date dateTime; // Original field
private Long dateTimeMillis;
@Column(name = "datetime")
@NotNull
@Convert(converter = DateConverter.class)
public Date getDateTime() {
return dateTime;
}
// Another mapping for the datetime column, will use this for criteria queries:
@Column(name = "datetime", updatable = false, insertable = false)
public Long getDateTimeMillis() {
return dateTimeMillis;
}
谓语：
Path<Long> pathDateTo = root.get(Transference_.dateTimeMillis);
Predicate predDateTo = cb.lessThanOrEqualTo(pathDateTo, this.dateTo.getTime());
predicates.add(predDateTo);
然后它按预期工作.
