我正在关注教程http://krams915.blogspot.ie/2011/01/spring-mvc-3-hibernate-annotations.html
当我输入localhost:8080 / tutorial / krams / main / persons到URL栏时,我遇到了麻烦。我一直收到404错误。我的顶级包是org.krams.tutorial,我已经将项目名称设置为教程。
(我在STS中使用Spring MVC模板。我删除了Home Controller.java和home.jsp。我不确定这是否有效.Spring MVC模板的目录结构与Krams教程不同当我下载Krams项目并在STS中运行它工作正常,但我想从头开始自己做。希望有人可以帮助我!它非常令人沮丧! 这是我的代码。

查看您的日志我可以看到您收到以下异常:
引起:java.lang.ClassNotFoundException:org.hibernate.cache.CacheProvider
快速查看Google会产生一个SO帖子here,该问题表明问题与您可能与spring结合使用的hibernate版本有关。使用建议的Factory编辑hibernate-context.xml可能会解决您的问题。
