java - 使用 Spring @Query 注解进行不区分大小写的查询

Question

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);

我想确保查询的第一部分(“and”之前)区分大小写。我尝试将其更改为:

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

但是当 Spring 尝试初始化应用程序上下文时，我得到一个 NullPointer:

但是，更奇怪的是，如果我编写删除一些 UPPER 调用，我可以让它启动:

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

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

Answer 1

我最终只对列名调用 UPPER 并依赖调用者以大写形式传递参数。所以我的查询最终为:

@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")

这解决了问题，但我仍然不确定为什么原始查询不起作用。
