Question

我正在使用榻榻米和弹簧数据榻榻米。为此，我安装了版本为5.5.1 build 3511的沙发床，并启用了测试桶。我已经用密码beer-sample创建了用户beer-sample，并向他添加了存储桶beer-sample的所有特权。

然后，我创建了this sample application，并配置了沙发床。当我启动该应用程序并为存储桶中的现有啤酒query启动时，出现异常：

我猜应该使用配置自动创建索引，但是也许我错了。

您正在BeerRepository中使用Spring的benchbase存储库界面。接口的findAll()方法希望使用Couchbase View来获取数据。因此，您需要在Couchbase中手动创建视图，或者可以用BeerRepository注释@ViewIndexed(designDoc = "beer", viewName = "all")界面，如果界面不存在，则会自动创建视图。

您所做的错误是用Beer注释了@ViewIndexed类，因为该注释应该用于您的Repository接口。有关注释here的更多信息。

所有这些，您还应该检查如何利用Couchbase的N1QL查询从Couchbase访问数据。您可以在存储库方法上使用@Query注解。有关使用@Query批注here的更多信息。
