org.hsqldb.HsqlException：连接异常：连接失败：java.io.EOFException
org.hsqldb.HsqlException: connection exception: connection failure: java.io.EOFException
我正在使用 HSQLDB 和 Hibernate 版本 4 和 Spring 版本 4 在 maven 项目 中。
但是同样我没有得到连接对象，得到以下异常。

虽然我正在获取 SesionFactory 参考，但是如果我尝试使用 getSessionFactory().openSession() 获取会话参考得到同样的错误。
xml文件中的配置部分如下：
<!-- =====================================sessionFactory==================================== -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="packagesToScan" value="com.mavenTest.model"/>

</bean>
我不明白连接失败的原因。所以请指导，这里面要做什么。
更改 xml 配置后 运行 问题就解决了。更改代码如下：
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
<property name="url" value="jdbc:hsqldb:mem:abc"/> <!-- jdbc:hsqldb:mem:. -->
