Spring Data Couchbase 索引问题

Question

我正在玩沙发底座和 spring 数据沙发底座。为此，我安装了 5.5.1 build 3511 版本的 couchbase 并启用了测试桶。我创建了用户 beer-sample，密码 beer-sample，并将他的所有权限添加到存储桶 beer-sample。

然后我为桶中的现有啤酒创建了 this sample application with configuration for couchbase. When I start the application and query 我收到异常：

com.couchbase.client.java.error.ViewDoesNotExistException: View beer/all does not exist.

我想索引应该是用我的配置自动创建的，但也许我错了。

您正在 BeerRepository 中使用 Spring 的 couchbase 存储库界面。接口的 findAll() 方法需要 Couchbase View 来获取数据。所以你需要在 couchbase 中手动创建视图，或者可以用 @ViewIndexed(designDoc = "beer", viewName = "all") 注释你的 BeerRepository 界面，如果它不存在，它将自动创建视图。

您犯的错误是将 Beer class 注释为 @ViewIndexed，因为该注释应该用于您的 Repository 接口。有关注释 here.

综上所述，您还应该查看利用 Couchbase 的 N1QL 查询从 Couchbase 访问数据。您可以在您的存储库方法上使用 @Query 注释。有关使用 @Query 注释 here.
