升级到1.7.0.RELEASE后出现NoClassDefFoundError [英] NoClassDefFoundError after upgrading to 1.7.0.RELEASE

问题描述

我试图在我的playframework项目中将应用程序从1.6.2.RELEASE升级到1.7.0.RELEASE. 插入查询工作正常，但是当spring-data尝试在获取针对查询的结果之后尝试使用类名对对象进行膨胀时，似乎会出现问题，如果针对查询没有结果，则它会返回一个空的arraylist而不会引发错误.

I was trying to upgrade my application from 1.6.2.RELEASE to 1.7.0.RELEASE in my playframework project. Insert queries are working fine but there seems to be an issue when spring-data tries to inflate the object using class name after fetching result against query, if there's no result against query then it returns an empty arraylist without throwing error.

1.7.0.RELEASE在另一个基于spring-integration框架的项目中运行良好.

1.7.0.RELEASE works fine in another project based on spring-integration framework.

推荐答案

我也遇到了此错误.我认为这是spring数据mongodb的错误.

I'm facing this error too. I think it's the bug of the spring data mongodb.

如果Db模型和所有服务，存储库都在一个项目中，则不会出现此类错误. 但是如果服务在另一个项目中，则可以100％复制.我找不到避免这种错误的方法.

If the Db model and all the service, repository are in one project, no such error. But if the service in another project, it can be reproduced 100%. I don't find a way to avoid this error.

现在，我正在尝试在mongodb持久层上使用OGM.

Now, I'm trying to use the OGM on the mongodb persistent layer.
