扩展JPA实体以添加属性和逻辑

使用

@Inheritance

@Entity@Table(name="TEST")@Inheritance(strategy=InheritanceType.SINGLE_TABLE)public class Test {    ...}@Entitypublic class ExtendedTest     extends Test {    ...}

要么

@MappedSuperclass

@MappedSuperclasspublic class Test {    ...}@Entitypublic class ExtendedTest     extends Test {    ...}
