Spring JPA CriteriaBuilder 未生成正确的 SQL

Question

我有以下标准构建器声明：

    CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
    CriteriaQuery<TestEntity> criteriaQuery = criteriaBuilder.createQuery(TestEntity.class);
    Root<TestEntity> itemRoot = criteriaQuery.from(TestEntity.class);
    criteriaQuery.select(itemRoot);

    javax.persistence.criteria.CriteriaBuilder.In inClause = criteriaBuilder.in(itemRoot.get("cost"));
    inClause.value(criteriaBuilder.literal(5.0d));

    javax.persistence.criteria.CriteriaBuilder.In inClause2 = criteriaBuilder.in(itemRoot.get("cost"));
    inClause2.value(criteriaBuilder.literal(5.0d));

    Predicate pred = criteriaBuilder.or(inClause, criteriaBuilder.and(inClause2, criteriaBuilder.like(itemRoot.get("name"), "%name%")));
    criteriaQuery.where(pred);
    TypedQuery typedQuery = entityManager.createQuery(criteriaQuery);
    List<TestEntity> list = typedQuery.getResultList();

这会产生以下 sql ：

select *
from test_entity testentity0_ 
where
    testentity0_.cost in (
        5.0
    ) 
    or (
        testentity0_.cost in (
            5.0
        )
    ) 
    and (
        testentity0_.name like ?
    )

但是 where 子句是错误的，我希望以下内容：

select *
from test_entity testentity0_ 
where
    testentity0_.cost in (
        5.0
    ) 
    or (
        testentity0_.cost in (
            5.0
        )
        and (
            testentity0_.name like ?
        )
    ) 

and 放错了位置，它应该放在 or 语句的第二个表达式中

Answer 1

这两个表达式是等价的，因为and 运算符优先于or：

A or B and C 等价于 A or (B and C)
