我是Hibernate的新手。在DB中我有一个数字[]，我试图在我的模型类中创建一个属性。我正在使用以下问题的代码 Hibernate, Postgres & Array Type 制作自定义用户类型。 我的模型类中的代码如下所示
@Type(type = " com.CustomUserType.ArrayUserType")
private Integer[] prefid;
@Column(name="prefid")
public Integer[] getPrefid() {
return this.prefid;
}
public void setPrefid(Integer[] prefid) {
this.prefid = prefid;
}
当我尝试使用HQL查询从表中访问行时，我得到序列化异常。 堆栈跟踪如下： -
