protected abstract void	addCondition(QueryWraper<T> queryWraper)
protected void	addFetch(javax.persistence.criteria.Root<T> root) 子类可以通过覆盖此方法实现关联抓取，避免n+1查询
protected javax.persistence.criteria.Predicate	getPermissionCondition(QueryWraper<T> queryWraper) 添加权限条件，如果要查询的domain实现了ManagedByOrgan接口，那么传入的Condition对象也应该实现 ManagedByOrgan接口， 程序会尝试从Condition对象获取organFullId,然后作为like查询条件添加到查询中。
javax.persistence.criteria.Predicate	toPredicate(javax.persistence.criteria.Root<T> root, javax.persistence.criteria.CriteriaQuery<?> query, javax.persistence.criteria.CriteriaBuilder cb) 构建查询条件，子类必须实现addCondition方法来编写查询的逻辑。

toPredicate

public javax.persistence.criteria.Predicate toPredicate(javax.persistence.criteria.Root<T> root,
                                                        javax.persistence.criteria.CriteriaQuery<?> query,

构建查询条件，子类必须实现addCondition方法来编写查询的逻辑。 子类可以通过addFetch方法控制查询的关联和抓取行为。

指定者:

toPredicate 在接口中 org.springframework.data.jpa.domain.Specification<T>

getPermissionCondition

protected javax.persistence.criteria.Predicate getPermissionCondition(QueryWraper<T> queryWraper)

添加权限条件，如果要查询的domain实现了ManagedByOrgan接口，那么传入的Condition对象也应该实现 ManagedByOrgan接口， 程序会尝试从Condition对象获取organFullId,然后作为like查询条件添加到查询中。 查出所有以传入的organFullId开头的domain.

参数:

queryWraper -

返回:

addFetch

protected void addFetch(javax.persistence.criteria.Root<T> root)

 子类可以通过覆盖此方法实现关联抓取，避免n+1查询
 
 

参数:

root -

addCondition

protected abstract void addCondition(QueryWraper<T> queryWraper)
