我正在使用spring hibernate集成框架。

以下是我的 applicationContext.xml :-

<bean id="DataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
    destroy-method="close">
    <property name="driverClass" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
    <property name="jdbcUrl" value="jdbc:sqlserver://localhost:49373/siya_hcm" />
    <property name="user" value="sa" />
    <property name="password" value="test@12345" />
    <property name="maxPoolSize" value="10" />
    <property name="maxStatements" value="0" />
    <property name="minPoolSize" value="5" />
</bean>

我使用的是sql server 2008。我不明白为什么会出现这个警告？我已经使用其他数据库(如 mysql 等)运行了具有相同配置的其他项目。但是这里，问题是什么？

不了解您的背景；您确定“49373/siya_hcm”是有效的端口号吗？我猜想一个有效的端口号应该只包含，嗯......一个数字？
