java - 使用Hibernate在HSQL数据库(内存中)中创建模式(注解方法)

Question

正在使用 hsqldb(在内存中)为 hibernate 项目(基于注释)创建 JUNIT 案例。但是表尚未创建。 由于实体的目录属性而发生错误(org.hsqldb.HsqlException:无效架构名称:TEST)。如果它被删除，我在尝试坚持时不会有任何问题。

但我需要提供架构。请让我知道您的意见/建议。 请在下面找到更多详细信息:-

Answer 1

使用的实体如下:-

    @Entity
    @Table(name="CITY")
    public class City {
        @Id
        @GeneratedValue
        @Column(name="CITY_ID",unique= true)
        private long id;

删除 id 属性的“唯一”标签后，表已成功创建。
