在Spring数据JpaRepository方法问题中的Pageable和@Param

问题描述

我有一个以下存储库：

public interface MilestoneRepository extends JpaRepository<Milestone,Date> {
    @Query("select m from Milestone m where m.date <= :date order by m.date desc")
    Page<Milestone> findLeftClosest(@Param("date") Date date, Pageable pageable);
}

定义如上所述正常，但如果我切换参数顺序：

Defined like above works ok, but if I switch the arguments order:

public interface MilestoneRepository extends JpaRepository<Milestone,Date> {
    @Query("select m from Milestone m where m.date <= :date order by m.date desc")
    Page<Milestone> findLeftClosest(Pageable pageable, @Param("date") Date date);
}

我在上下文初始化时遇到以下异常（发布最有趣的底层原因） ：

I get a following exception on context initialization (posting the most interesting bottom cause):

Caused by: java.lang.IllegalArgumentException: Either use @Param on all parameters except Pageable and Sort typed once, or none at all!

这看起来像是一个错误我。我的感觉对不对？有人知道有关于此的报道问题吗？或许这可以在某处记录并证明行为合理？

This looks like a bug to me. Is my feeling right? Anyone aware of a reported issue on that? Or maybe this is documented somewhere and justified behavior?

spring-data-jpa版本：

The spring-data-jpa version:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.5.2.RELEASE</version>
</dependency>

推荐答案

这确实是一个错误。我提交并修复了，这将进入Spring Data Commons 1.7.3,1.8.1和1.9 M1。

This is a bug indeed. I filed and fixed DATACMNS-520 which will make it into Spring Data Commons 1.7.3, 1.8.1 and 1.9 M1.
