java mybits集成 数据类型转换错误
java中的Long类型对应mybits的javaType是什么类型，我用BIGINT的，但是修改的时候报错
Exception in thread "main" org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException: 
### Error updating database. Cause: java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer

------解决方案--------------------
java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer你把Long类型的定义为Integer了。看看实体类和数据库里的类型是否有差别。
