Java 如何解决org.apache.commons.dbcp.SQLNestedException

我使用hsqldb standalone作为我的数据库。我在项目构建路径中添加了一个

hsqldb.jar（hsqldb-2.0.0）

，这样我的项目就会发现我的

hsqldb.jar在哪里。我用的是弹簧。我的春豆是：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <bean id="sqlMapClient"
        class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">

        <property name="dataSource">
            <ref local="adapterDataSource" />
        </property>


        <property name="configLocation"
            value="classpath:/com/hsqldb/example/dao/ibatis/SqlMapConfig.xml" />


    </bean>

    <bean id="adapterDataSource"
        class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="org.hsqldb.jdbcDriver" />
        <property name="url" value="data/db/hsqldb.jar" />
        <property name="username" value="SA" />
        <property name="password" value="password" />
    </bean>
    <bean id="testingDao" class="com.hsqldb.example.dao.TestingDao"
        init-method="setTestDao" depends-on="moodleAuthenticationDetails">
        <property name="sqlMapClient">
            <ref local="sqlMapClient" />
        </property>

    </bean>
    <bean id="moodleAuthenticationDetails"
        class="com.hsqldb.example.HsqlDBAuthentication"></bean>
</beans> 

但在通过junit测试运行测试用例时，它给了我一个异常：

org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class 'org.hsqldb.jdbcDriver' for connect URL 'data/db/hsqldb.jar'

请帮助解决此问题

谢谢
Spring配置中的
BasicDataSource
url
属性不应该是jar的路径。请参阅工作弹簧配置的一些示例

（您编写的
DataSource
类不会做任何事情，除非您让Spring意识到它。但是您不必编写这样的类——只需修复配置中的
url
属性即可。）
