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>
我正在使用sql server 2008。
我不明白为什么会出现这个警告？
我已经运行了与其他数据库（例如mysql等）具有相同配置的其他项目。但是，这是什么问题呢？
最佳答案
不了解你的背景；您确定“ 49373 / siya_hcm”是有效的端口号吗？我想一个有效的端口号应该只包含一个数字？
