我有通过JPA注释映射的父子实体：
我创建父实体的新实例，添加一些字段并从JPA提供程序调用persist方法。我有不必要的SQL更新。 为什么冬眠会产生它？
Hibernate: insert into field_type (id) values (?)
Hibernate: insert into template (id, client_id, name) values (default, ?, ?)
Hibernate: select template_f_.id from field_type template_f_ where template_f_.id=?
Hibernate: insert into field (id, field_name_id, operation_template_id, field_value) values (default, ?, ?, ?)
(!) Hibernate: update field set operation_template_id=? where id=?
