Please help me!

For future reference, this is a known issue.
See https://github.com/mybatis/mybatis-3/issues/623
TL;DR
Upgrading to MyBatis 3.4.2+ AND Java 1.8.0_25+ should fix the problem.
If you cannot upgrade, there seems to be a workaround.
The error seems pretty straightforward. The property masFlag does not exist in the parameter object.
Does the class com.xxx.xxx.batch.model.pojo.XXXXXXXInfo has that property and/or getter & setter?
Otherwise, post the < mapper >.
