JPA中⾼级查询怎样实现join⼦查询如SQL：select assets_entity.* from assets_entity

left join ( select inventory__entity_id from inventory_recording where inventory_ory_task_id = ?) as irr

on assets_ = _entity_id

where _entity_id is null;下⾯是我写到⼀半的，可是不知道怎么放⼦查询private void listsss(){ Specification specification = new Specification() { @Override public Predicate toPredicate(Root root, CriteriaQuery criteriaQuery, CriteriaBuilder criteriaBuilder) { //Path assetsNumberPath = ("assetsNumber"); // 完成⼦查询 Subquery subQuery = ry(); Root IRFrom = (); (("assetsEntity")).where((("inventoryTask"), 1L)); // left join List predicates = new ArrayList<>(); Predicate[] array = new Predicate[()]; (y(array)); return null; }
