德鲁伊遇到的创建bean异常问题

错误根源：Caused by: java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'java.sql.Driver' for property 'driver': no matching editors or conversion strategy found
at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:262)

原因：在用德鲁伊数据池配置连接数据库的配置文件中，在之前版本中使用类名，但是后面的版本中使用的String 类型的driverClass 

所以在创建dataSourse的bean中name = "driverClassName" value="${jdbc.driver}"

 

 

 

 

之前版本中使用的

正确的配置

 

 

 

 在看源码的时候发现：driver的配置可以为空，可以根据url配置驱动类型
