Spring-Hibernate:无法实例化DataSource,提示DataSource的构造函数抛出空指针异常
Spring-Hibernate整合,报错:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in URL [file:/D:/DevelopTools/apache-tomcat-7.0.54/webapps/HMQMP/WEB-INF/classes/applicationContext.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in URL [file:/D:/DevelopTools/apache-tomcat-7.0.54/webapps/HMQMP/WEB-INF/classes/applicationContext.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in URL [file:/D:/DevelopTools/apache-tomcat-7.0.54/webapps/HMQMP/WEB-INF/classes/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.jolbox.bonecp.BoneCPDataSource]: Constructor threw exception; nested exception is java.lang.NullPointerException

at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1417)
提示无法实例化DataSource,因为DataSource的构造函数抛出了空指针异常,
检查Spring和Hibernate整合的配置文件,没发现错误,配置文件如下:
applicationContext.xml:
<bean id="dataSource" class="com.jolbox.bonecp.BoneCPDataSource"
destroy-method="close">
<property name="driverClass" value="${jdbc.driverClassName}" />
<property name="jdbcUrl" value="${jdbc.url}" />

</props>
</property>
<!-- hibernate annotation config -->
<property name="packagesToScan" value="com.goodwill" />
</bean>
请大家帮忙看下,这里是什么问题啊?
