我们在演示项目中使用eclipselink和springframework ，我们没有使用Spring MVC。

we are using eclipselink ,springframework in our demo project, We are not using Spring MVC.

推荐答案

似乎与bug ，已在休眠状态5.3.0.CR1中修复。

Seems to be related to bug HV-1013, fixed in hibernate 5.3.0.CR1.

这篇关于javax.validation.ValidationException：HV000041：调用TraversableResolver.isReachable（）引发了异常的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
