配置hibernate问题

[coolszy]

我配置hibernate
其中hibernate.cfg.xml配置如下

<session-factory>
		<!--配置数据库连接 -->
		<property name="connection.url">
			jdbc:oracle:thin:@localhost:1521:orcl
		</property>
		<property name="connection.username">scott</property>
		<property name="connection.password">tigger</property>
		<property name="connection.driver_class">
			oracle.jdbc.driver.OracleDriver
		</property>
		<property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>
		<!-- 是否打印Sql语句 -->
		<property name="hibernate.show_sql">true</property>

		<mapping resource="com/szy/hibernate/user.hbm.xml" />
	</session-factory>

user.hbm.xml文件如下配置

<hibernate-mapping package="com.szy.hibernate">
 <class name="User" table="t_user">
  <id column="ID" name="id" length="10" type="java.lang.String">
   <generator class="assigned"/>
  </id>
  <property column="USERNAME" name="username" type="java.lang.String" length="20" not-null="true" unique="true"/>
  <property column="PASSWORD" name="password" type="java.lang.String" length="20"/>
  <property column="AGE" generated="never" lazy="false" name="age" type="java.lang.Integer"/>
 </class>
</hibernate-mapping>

数据库是通过以下代码生成的

Configuration config=new Configuration().configure();
		SchemaExport export=new SchemaExport(config);
		export.create(true, true);

测试代码如下

User user=new User();
		user.setId("001");
		user.setUsername("coolszy");
		user.setPassword("test");
		user.setAge(21);
		
		Session session=HibernateUtil.getSession();
		Transaction ts=session.beginTransaction();
		session.save(user);
		ts.commit();

其中HibernateUtil是过去session的工具类
运行时老是报下面的错误

Exception in thread "main" java.lang.AbstractMethodError:
oracle.jdbc.driver.OracleDatabaseMetaData.supportsGetGeneratedKeys()Z

at com.szy.hibernate.HibernateUtil.<clinit>(HibernateUtil.java:10)
at com.szy.hibernate.Test.main(Test.java:14)

不知怎么解决，请高手赐教

<property column="PASSWORD" name="password" type="java.lang.String" length="20"/>
type是指hibernate的数据类型吧,应该写成string

楼上正解

[coolszy]

我的这种写法是Java类型的
在Mysql中是可以使用的
