因为Hibernate中主键设为自增的，hibernate中的实体类与数据库的映射文件中配置数据库 的Sequence
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="com.zhaogd.myapplication.model.SysUser" table="SYS_USER">
<id name="id">
<!--主键生产策略 -->
<generator class="native">
<!--SEQ_SYS_USER 为orcale中创建的sequence-->
<param name="sequence">SEQ_SYS_USER</param>
</generator>
</id>
<!--实体类属性-->
<property name="username" />
<property name="password" />
</class>
</hibernate-mapping>
至于orcale中如何创建sequence
-- Create sequence create sequence SEQ_SYS_USER minvalue 1 maxvalue 999999999999999999 start with 21 increment by 1 cache 20;
