Spring Data Couchbase 2.2.0M1 raises java.lang.NoClassDefFoundError: com/couchbase/client/java/query/Query error in my SprintBoot app
Spring Data Couchbase 2.2.0M1 raises java.lang.NoClassDefFoundError: com/couchbase/client/java/query/Query error in my SprintBoot app
我试图在我的 SpringBoot 项目中使用 SpringDataCouchbase 2.2.0M1（原因是 N1QL 支持）。我已经正确设置了所有内容（我有 com.couchbase.client:java-client:2.2.2 作为依赖项）但是当应用程序启动时它会引发如下错误。它是内部的东西，我尝试了旧的 couchbase 驱动程序 (2.2.0)，但它是一样的。有没有人可以提供合适的提示？

M1 是在 2.2 SDK 仍为开发者预览版（同样不稳定，2.2.0-dp）时发布的一个里程碑。当 2.2.0 正式发布时，大多数与 N1QL 相关的 类 已重命名为具有 N1ql 前缀，以保持一致性。
所以 Query 在 2.2.0-dp 和 2.2.0.
之间变成了 N1qlQuery（与 ViewQuery 和 SpatialViewQuery 平行）
如果您没有在 Maven 中明确设置对 Couchbase SDK 的依赖项，它会拉取正确的依赖项 (2.2.0-dp)，并且一切正常。请注意，您必须将 Maven 存储库添加到您的配置中，如 blog post announcing SDC 2.0-M1.
末尾所述
自第一个里程碑以来，Spring Data Couchbase 已经投入了大量工作，因此期待很快发布候选版本，随后将很快发布 GA（两者都应该基于更稳定和最新的SDK 2.2.2).
感谢您的尝试，请务必报告您看到的任何错误（在 Spring 的 issue tracker or also on the Couchbase forums 中，我会密切监控）。
