java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
检查你SQL数据库驱动jar包是不是加上了？
检查dataSources配置的property信息是否正确

ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
SQLServerDriver的jar文件放到libs里了吗？

[子忆]

<bean id="dataSources" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"></property>
<property name="password" value = "sa"/>
<property name="url" value = "jdbc:sqlserver://172.19.100.118:1433;databaseName=youbao"/>
<property name="username" value="sa"/>
</bean>
这是我配置数据源的地方，请帮忙检查哪里有问题
