Unknown host exception when configuring HikariCP with MS sql driver - sql-server

Question

Here is my Hikari datasource configuration:
<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>
Here is the stack trace:
java.sql.SQLTransientConnectionException: springHikariCP - Connection is not available, request timed out after 1003ms.

The above line is what I have been focusing on. I've tried using just the IP address instead of the server name.
I've tried using dataSourceClassName with same result:
<property name="dataSourceClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDataSource" />
All with the same result. I am able to connect using a different datasource. I am also able to connect using sqlcmd.
I've looked at the many SO already existing questions and it appears my configuration should work.

How to set up datasource with Spring for HikariCP?
As well as the hikariCP documentation.
I can't see anything wrong with the setup. Why am I getting the unknown host exception? Another set of eyes would be greatly appreciated.

Answer 1

Get rid of the jdbcUrl. Also, there are quotes around your hostname/instance, there probably shouldn't be. You can also separate the instance from the host in the configuration as below:
<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>
