查询生成器中的 JPA 2.0 谓词条件列表

JPA 2.0 predicate condition lists in query builder

代码:

List<Predicate> conditionsList = new ArrayList<Predicate>();
Predicate onStart = criteriaBuilder.greaterThanOrEqualTo(criteriaRoot.get("insertDateTime"), startTradeDate);
Predicate onEnd = criteriaBuilder.lessThanOrEqualTo(criteriaRoot.get("insertDateTime"), endTradeDate);
conditionsList.add(onStart);
conditionsList.add(onEnd);

CriteriaBuilder criteriaBuilder = this.entityManager.getCriteriaBuilder();
CriteriaQuery<MyClass> criteriaQuery = 
criteriaBuilder.createQuery(MyClass.class);
Root<MyClass> criteriaRoot = criteriaQuery.from(MyClass.class);
criteriaQuery.select(criteriaRoot).where(conditionsList);

上面的最后一行没有编译,因为它期望 conditionsList 对象是布尔列表而不是谓词列表。

请告诉我将上述谓词添加到 hibernate 标准的正确方法?

List<Predicate> 转换为数组 Predicate[],如下所示:

criteriaQuery.select(criteriaRoot).where(conditionsList.toArray(new Predicate[] {}));
