【问题描述】：

尝试使用 jdbc 将我在 Tomcat 上的 Java Spring 应用程序连接到我的 sqlserver 数据库。 得到错误：

"请求处理失败；嵌套异常是 org.springframework.jdbc.CannotGetJdbcConnectionException: 不能 获取 JDBC 连接；嵌套异常是 org.apache.commons.dbcp.SQLNestedException：无法创建 PoolableConnectionFactory（与主机 BEN-790 的连接，名为 实例 sqlexpress 失败。错误：“java.net.SocketTimeoutException： 接收超时”。验证服务器和实例名称并检查 没有防火墙阻止到端口 1434 的 UDP 流量。对于 SQL Server 2005 或更高版本，验证 SQL Server Browser 服务是否正在运行 在主机上。）”

【问题讨论】：

您的机器似乎没有连接到数据库服务器。您可以将客户端工具连接到它吗？

是的，我可以使用 MS SQL Server 从数据库的表中选择数据。所以我有我的连接并且浏览器服务正在运行。

【参考方案1】：

为此更改连接 bean 怎么样？

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
        <!-- S2-Install-Start: INSERT DB SERVER HERE -->
        <property name="url" value="jdbc:sqlserver://localhost:1433;DatabaseName=MyDatabase;" />
        S2-Install-End:
        <property name="username" value="Stefana\Steffi" />
        S2-Install-Start: INSERT DB PASSWORD HERE
        <property name="password" value="" />
        S2-Install-End:
    </bean>

【参考方案2】：

+1 jpganz 18，修复了它。我将类更改为“org.springframework.jdbc.datasource.DriverManagerDataSource”，并将 url 更改为 localhost:1433，然后它就起作用了。
