我在JpaRepository中有自定义方法，它们是递归调用的。firstMethod实际上是从DB调用数据。secondMethod和thirdMethod分别调用firstMethod和secondMethod。
thirdMethod是否在单个事务中执行？即，我希望整个查询列表在一次执行中被触发，从数据库中获取整个列表并在一次执行中返回，而不是在列表中的每个对象上触发多个查询。

public interface SomeDao extends JpaRepository<SomeObject, SomeObjectId> {

    @Deprecated
    @Query("custom query")
    Slice<SomeObject> firstMethod(BigInteger a, Timestamp b, Pageable c);

    default Optional<SomeOtherObject> secondMethod(SomeObject someObject) {
        // calls first method
        // object has separate fields that apply in first method -> someObject.a, someObject.b etc
    }

    // I want to know whether third method gets executed in single transaction???
    default List<Optional<SomeOtherObject>> thirdMethod(List<SomeObject> listOfObjects) {
        // calls second method for a list of objects
    }
}
