hibernate主键

<span style="color: rgb(102, 102, 102); font-family: Helvetica, Tahoma, Arial, sans-serif; font-size: 14px; line-height: 25px;">一、JPA通用策略生成器 通过annotation来映射hibernate实体的,基于annotation的hibernate主键标识为@Id, 其生成规则由@GeneratedValue设定的.这里的@id和@GeneratedValue都是JPA的标准用法, JPA提供四种标准用法,由@GeneratedValue的源代码可以明显看出. </span><span style="color: rgb(85, 85, 85);

font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">native: 对于 oracle 采用 Sequence 方式，对于MySQL 和 SQL Server 采用identity（自增主键生成机制），native就是将主键的生成工作交由数据库完成，hibernate不管（很常用）。 </span><br style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">uuid: 采用128位的uuid算法生成主键，uuid被编码为一个32位16进制数字的字符串。占用空间大（字符串类型）。 </span><br style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">hilo: 使用hilo生成策略，要在数据库中建立一张额外的表，默认表名为hibernate_unique_key,默认字段为integer类型，名称是next_hi（比较少用）。 </span><br style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">assigned: 在插入数据的时候主键由程序处理（很常用），这是 <generator>元素没有指定时的默认生成策略。等同于JPA中的AUTO。 </span><br style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">identity: 使用SQL Server 和 MySQL 的自增字段，这个方法不能放到 Oracle 中，Oracle 不支持自增字段，要设定sequence（MySQL 和 SQL Server 中很常用）。 </span><br style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">          等同于JPA中的INDENTITY。 </span><br style="color: rgb(85, 85, 85);

font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">sequence: 调用底层数据库的序列来生成主键，要设定序列名，不然hibernate无法找到。 </span><br style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">seqhilo: 通过hilo算法实现，但是主键历史保存在Sequence中，适用于支持 Sequence 的数据库，如 Oracle（比较少用） </span><br style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">increment: 插入数据的时候hibernate会给主键添加一个自增的主键，但是一个hibernate实例就维护一个计数器，所以在多个实例运行的时候不能使用这个方法。 </span><br style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;" /><span style="color: rgb(85, 85, 85); font-family: 'microsoft yahei'; font-size: 15px; line-height: 35px;">foreign: 使用另外一个相关联的对象的主键。通常和<one-to-one>联合起来使用。 </span><br style="color: rgb(85, 85, 85);
