使用 net.sourceforge.jtds.jdbc.Driver 将 SpringMVC 与 JDBC 连接时出错

Question

我正在尝试用 JDBC 模板做 SpringMVC。（使用 SQL SERVER 2008 数据库）

我包含了连接数据库所需的所有 jars。

这是我的数据库连接 bean 编码

<!-- declare datasource bean -->
<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver" />
    <property name="url" value="jdbc:jtds:sqlserver://127.0.0.1:1098/userdb" />
    <property name="username" value="root" />
    <property name="password" value="root" />
</bean>

当我尝试连接数据库时，我得到了这个错误。

您的数据库连接 URL 似乎不正确或数据库服务器不可用。您能否通过使用某些客户端工具进行日志记录来验证这一点？
