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：

引起：com.microsoft.sqlserver.jdbc.SQLServerException：与主机＆＃34; DEVWORX01的连接，命名为实例DEV2014＆＃34;失败。错误：＆＃34; java.net.UnknownHostException：＆＃34; DEVWORX01＆＃34;。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，请验证主机上是否正在运行SQL Server Browser服务。
上述内容是我一直关注的内容。我曾尝试仅使用IP地址而不是服务器名称。
我尝试过使用dataSourceClassName，结果相同：
<property name="dataSourceClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDataSource" />
所有结果都相同。我能够使用不同的数据源进行连接。我也可以使用sqlcmd进行连接。
我已经查看了许多已经存在的问题，看来我的配置应该可行。 implementing hikaricp with microsoft sql server
How to set up datasource with Spring for HikariCP?
我无法看到设置有任何问题。为什么我会收到未知主机异常？另一组眼睛将非常感激。
答案 0 :(得分：1)
摆脱jdbcUrl。此外，您的主机名/实例周围有引号，可能不应该。您还可以在配置中将实例与主机分开，如下所示：
<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
<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="SELECT 1"/>
<property name="dataSourceClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDataSource" />
<property name="dataSourceProperties">
<props>
<prop key="serverName">DEVWORX01</prop>
<prop key="instanceName">DEV2014</prop>
<prop key="databaseName">NexGen</prop>
<prop key="user">nexgen</prop>
<prop key="password">nexgen</prop>
</props>
</property>
</bean>
