为什么我得到这个异常，因为所有的3个bean都是在dispatcher-servlet.xml中定义的文件。
我指的是以下 source 来整合Hibernate。
java.lang.NoClassDefFoundError：Lorg / hibernate / cache / CacheProvider 缺少jar。
你是部分正确的..有一个瓶子不匹配..如此处所述.. howtodoinjava.com/2013/12/08/...。但添加后，我得到一个错误，WEB-INF / inspireme-dispatcher-servlet.xml：调用init方法失败;嵌套异常是java.io.FileNotFoundException：类路径esource [hibernate.cfg.xml]不能被解析为URL，因为它不存在。
不完全确定构建如何在您的案例中工作但试试 classpath：/hibernate/hibernate.cfg.xml 或 classpath：hibernate / hibernate.cfg.xml 。或者在部署的战争中更好地检查该文件在 WEB-INF / classes 内的位置。
Following is the exception which I am getting while I am trying to integrate Hibernate with my Spring MVC project and add Autowired feature.

Why am I getting this exception since all the 3 beans, are defined in the dispatcher-servlet.xml file.
I am referring the following source to integrate Hibernate.
java.lang.NoClassDefFoundError: Lorg/hibernate/cache/CacheProvider jar is missing.
You are partially correct .. there is a jar mismatch .. as stated here .. howtodoinjava.com/2013/12/08/…. But after adding this I am getting an error, "WEB-INF/inspireme-dispatcher-servlet.xml]: Invocation of init method failed; nested exception is java.io.FileNotFoundException: class path esource [hibernate.cfg.xml] cannot be resolved to URL because it does not exist". Please look at my folder structure and let me know how to give the path here.
Not exactly sure how the build works in your case but try classpath:/hibernate/hibernate.cfg.xml or classpath:hibernate/hibernate.cfg.xml. Or better check where exactly that file is within WEB-INF/classes in the deployed war.
