问题摘要：

org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc.SQLServerDriver '

原因：配置文件driverClassName后面多了一个空格。

其实一开始我并未注意到这个空格，只是按常规思路，先排查这个jar包是否存在。

没问题，运行是jar包是否正常加载，也正常。万分苦恼，最后无意中发现有个空格。

错误详细：
