Java 类型'；org/springframework/http/MediaType'；（当前帧，堆栈[1]）不可分配给'；org/springframework/util/MimeType'；

我已将spring从3.2.1升级到4.0.3

得到：

"Type 'org/springframework/http/MediaType' (current frame, stack[1]) is 
 not assignable to 'org/springframework/util/MimeType'"

完整堆栈跟踪：

spring问题在我的理解中是隐藏的，可能是什么，从哪里开始搜索？

我认为，这不是升级问题。当应用程序服务器卡住时会发生这种情况。所以，您需要删除服务器并在服务器上运行。

我要说的是检查您的依赖项/类路径。我希望某个地方会有一个冲突的jar（不同的版本）。有同样的问题。使用弹簧4.0.5。删除部署描述符并重新启动服务器后，服务器将再次开始工作。对于NetBeans 8.0.2中的tomee app server 1.7.1，spring 4.0.2是可复制的。这与实际情况非常接近：在删除部署描述符并重新启动后，它再次工作。我在其他系统中遇到了相同的问题（不是spring），但我无法修复它。问题是：。任何建议都是有益的。
