自己在用idea自动导包使用spring框架的时候 出现如下错误异常：

Exception in thread "main" java.lang.IllegalStateException: Could not load JDBC driver class [com.mysql.jdbc.Driver]
    	at org.springframework.jdbc.datasource.DriverManagerDataSource.setDriverClassName(DriverManagerDataSource.java:130)

这应该是找不到包的异常，之后导入驱动jar包就好了：
