我有以下問題。 我使用了spring-data,我想爲Long Property創建一個「like」語句。Spring Data JPA:具有「like」和long的規範
我試過以下,但沒有成功。
private Specification<T> createSpecification()
{
return new Specification<T>()
{
@Override
public Predicate toPredicate(final Root<T> root, final CriteriaQuery<?> query, final CriteriaBuilder cb)
{
final Predicate like = query.where(cb.like(root.<String> get("kundenNr"), "%4%")).getRestriction();
return like;
}
};
}
和領域類
public class Kunde implements Serializable
{
@ColumnYB(lable = "KundenNr.", order = 1)
@Id
@javax.persistence.Column(nullable = false, name = "kundennr")
protected Long kundenNr;
@ColumnYB(lable = "Deaktiviert")
@Column(nullable = false)
private boolean deaktiviert = false;
@Column(name = "kundenart")
private String kundenart;
...
我碰到下面的錯誤。

我做錯了什麼?
