You should upgrade spring-coreartifact to 4.0 version.
您应该将spring-coreartifact升级到 4.0 版本。
回答by Jeevan Patil
You have some spring dependencies of version 3.1.3.RELEASEand some of 4.0.2.RELEASE. Try using dependencies of same version. I guess mixed versions of spring dependencies is causing the problems.
您有一些 spring 版本的依赖项3.1.3.RELEASE和一些4.0.2.RELEASE. 尝试使用相同版本的依赖项。我猜 spring 依赖项的混合版本导致了这些问题。
