我搭建了一个struts2,spring,myibatis框架在spring的配置中driver的
value='com.mysql.jdbc.Driver'改成value=${jdbc.driver}就报错，
使用的是proxool-0.9.1.jar,proxool-cglib.jar
<!--配置数据源属性文件 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- config for proxool datasource -->
<bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource">
<property name="alias" value="doo-proxool" />
<property name="driver" value="${jdbc.driver}" />
<property name="driverUrl" value="jdbc:mysql://localhost:3306/doo?useUnicode=true&characterEncoding=UTF-8"/>
<property name="user" value="root" />
<property name="password" value="root" />
</bean>
报错的内容如下:
