why Spring-data-jpa didnot save the subclass object? - spring-data-jpa

Question

The reason for this problem is a configuration. Hibernate have a configuration: hibernate.default_batch_fetch_size, so I just added it in application.properties as: spring.jpa.properties.hibernate.jdbc.batch_size(wrong), however you cannot find it in Appendix A. Common application properties. It works for me by deleting this property.
finally, why springboot didnot throw a execption, if he cannot understand this property? Why this error property can interference the commit of transaction?
update2 hibernate sql log
Update1 user and student classes code.
By the way, it was an old project and worked fine with spring 5.0.4 and JPA2.1(Hibernate 5.2.14). I am studying and trying to migrate this project to springboot and spring-data-jpa.
I had a very very weird problem. When I am trying to persit a subclass object to database, spring data jpa can only persist the superclass properties into superclass table, but nothing in the subclass table. And if persist two subclass object at one time, the first object can be saved to subclass table, but the second will be Ignored. However, the insert sql statement seem to be executed(at least it showed in the console).
