We use MSSQL as our data base server and use 'com.microsoft.sqlserver.jdbc.SQLServerXADataSource' as driver class.
Here some issues occured, the SQLServerXADataSource url property name is 'URL' not 'url', so we can't connect the data base server.

Environments:

1.JDBC driver is 'mssql-jdbc.7.2.2.jre8'
