Class TableSeqGenerator

java.lang.Object

org.hibernate.id.enhanced.SequenceStyleGenerator

org.beangle.orm.hibernate.TableSeqGenerator

All Implemented Interfaces:

org.hibernate.id.BulkInsertionCapableIdentifierGenerator, org.hibernate.id.Configurable, org.hibernate.id.IdentifierGenerator, org.hibernate.id.PersistentIdentifierGenerator

public class TableSeqGenerator
extends org.hibernate.id.enhanced.SequenceStyleGenerator

按照表明进行命名序列
依据命名模式进行，默认模式{table}_seq
该生成器可以

 1)具有较好的数据库移植性，支持没有sequence的数据库。
 2)可以通过设置优化起进行优化
 3)可以按照表名进行自动命名序列名，模式{table}_seq
