【问题描述】：
这是我的 Hikari 数据源配置：
<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
<property name="jdbcUrl" value="jdbc:sqlserver://" />
<property name="initializationFailFast" value="false"/>
<property name="poolName" value="springHikariCP" />
<property name="username" value="nexgen"/>
<property name="password" value="nexgen"/>
<property name="connectionTimeout" value="1000"/>
<property name="connectionTestQuery" value="USE NexGen;SELECT TOP 1 * FROM Transactions"/>
<property name="dataSourceProperties">
<props>
<prop key="serverName">"DEVWORX01\DEV2014"</prop>
<prop key="databaseName">NexGen</prop>
<prop key="user">nexgen</prop>
<prop key="password">nexgen</prop>
</props>
</property>
</bean>
这是堆栈跟踪：

原因：com.microsoft.sqlserver.jdbc.SQLServerException：与主机“DEVWORX01，命名实例 DEV2014”的连接失败。错误：“java.net.UnknownHostException:”DEVWORX01”。验证服务器和实例名称并检查是否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 服务是否在主持人。
上面这行是我一直关注的。我试过只使用 IP 地址而不是服务器名称。
我尝试使用 dataSourceClassName 得到相同的结果：
<property name="dataSourceClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDataSource" />
所有结果都相同。我可以使用不同的数据源进行连接。我也可以使用 sqlcmd 进行连接。
我查看了许多已经存在的问题，看来我的配置应该可以工作。 implementing hikaricp with microsoft sql server

我看不出设置有什么问题。为什么我会收到未知主机异常？另一组眼睛将不胜感激。
【问题讨论】：
-
您能否使用 SQL Studio 或 Excel 或其他工具连接到 SQL Server？那里的连接字符串看起来如何？
-
是的，我可以使用上面配置中使用的用户名和密码连接 SSMS。我也可以使用 sqlcmd -S 192.168.16.163\DEV2014 -U nexgen -P nexgen -d NexGen 与 sqlcmd 连接
-
如果您尝试使用 IP 地址，您应该无法获得 UnknownHostException。可能是连接被拒绝或其他错误。使用 IP 地址时遇到什么异常？
