Java 使用Spring@query注释的不区分大小写的查询

我有一个Spring JPA存储库，其中有一个自定义查询：

@Query("select aif from AssetInFolder aif "
        + "where (aif.asset.name like %:name% "
        + "or aif.folder.name like %:name% "
        + "or aif.asset.assetCode like :code%) "
        + "and aif.folder.assetVersion.id = :version")
public List<AssetInFolder> searchForAsset(@Param("name") String name, @Param("code") String code,  @Param("version") int version);

但当Spring尝试初始化应用程序上下文时，我得到了一个空指针：

有人有什么想法吗？我使用的是Spring 4.2.2和Spring数据JPA 1.9.0

我最终只调用了列名的上限，并依赖调用者以大写形式传递参数。因此，我的问题是：

@Query("select aif from AssetInFolder aif "
            + "where (UPPER(aif.asset.name) like %:name% "
            + "or UPPER(aif.folder.name) like %:name% "
            + "or UPPER(aif.asset.assetCode) like :code%) "
            + "and aif.folder.assetVersion.id = :version")

---

这解决了这个问题，但是我仍然不确定原始查询为什么不起作用。

我删除了我的答案，因为它不再相关。你说“…我可以通过删除一些较高的调用来启动它”；这是什么意思？这样做会使上下文初始化吗？我不确定什么会导致stacktrace显示的NullPointerException。你能增量地把UPPER添加回去，看看什么时候会出错吗？是的，你是对的，当我删除所有对UPPER的调用时，应用程序上下文被正确初始化，没有错误。我是通过逐步添加回电话的方式得到这个职位的。我删除了我的答案，因为它不再相关。你说“我可以通过删除一些上级电话来启动它”；这是什么意思？这样做会使上下文初始化吗？我不确定什么会导致stacktrace显示的NullPointerException。你能增量地把UPPER添加回去，看看什么时候会出错吗？是的，你是对的，当我删除所有对UPPER的调用时，应用程序上下文被正确初始化，没有错误。我就是这样逐渐地把电话打回来的。
