show_sql不是org.apache.commons.dbcp.BasicDataSource的属性。您必须在会话工厂配置中定义它。像这样
<bean id="sessionFactory" > <property name="dataSource" ref="dataSource" /> <property name="packagesToScan" value="data" /> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop> <prop key="hibernate.current_session_context_class">thread</prop> <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> </props> </property></bean>
