春天打開jpa db2錯誤

Question

我的spring jpa poc未能獲取存儲庫注入。拋出異常

java.lang.IllegalArgumentException：接口必須使用@ org.springframework.data.repository.RepositoryDe​​finition註釋！

我給我所有的soruce代碼，以便它可以用一個誰通過這個

Answer 1

接口定義如下：

public interface PushAppsRepository extends JpaRepository<PushApps, Long> { 

    List<PushApps> findByAppId(long appId); 

} 

但是在實體的屬性是 'APPID'。我猜測掃描儀將無法解決此查詢，然後將期待某種實施。

將'appid'更改爲appId。或者更好的是仍然去除它競爭。您的接口將繼承JPARepository中的方法findOne（）或getOne（），您可以使用該方法通過PK檢索實體。

Answer 2

您確定堆棧跟蹤是指您上面顯示的PushAppsRepository？只有當我們發現一個存儲庫接口不是以某種方式擴展Spring Data的Repository（您明確表達的那個）時，纔會拋出異常。

它可能有助於調試RepositoryFactorySupport.getRepositoryMetadata(…)並看看爲什麼分配檢查在那裏失敗。
