使用 MS sql 驱动程序配置 HikariCP 时出现未知主机异常
Unknown host exception when configuring HikariCP with MS sql driver
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：
