org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [spring/spring-dao.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'minPollSize' of bean class [com.mchange.v2.c3p0.ComboPooledDataSource]: Bean property 'minPollSize' is not writable or has an invalid setter method. Did you mean 'minPoolSize'?

这个错误怎么解决？求大神指教
