项目启动时，spring配置文件报错?报错

错误显示如下：

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

以下是我的相关配置：

<!-- 定义数据源Bean，使用C3P0数据源实现 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="${jdbc.driverClassName}"/>
        <property name="jdbcUrl" value="{jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.username}"/>
    </bean>
	

	<!-- 定义DbUtils的一个模板操作Bean -->  
	<bean id="dbUtilsTemplate" class="com.lwj.common.util.DbUtilsTemplate">  
   		<property name="dataSource" ref="dataSource" />  
	</bean>
