Java 创建bean sessionFactory时发生不兼容的ClassChangeError

我一直在学习的教程。我把所有的东西都打进去了。但有些人却有例外

我正在使用tomcat 7和jre 7

这是我的web.xml

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<context-param>
   <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/hibernateDataAccessContext.xml /WEB-INF/applicationContext.xml
   </param-value>
 </context-param>

 <listener>
     <listener-class>org.springframework.web.context.ContextLoaderListener
 </listener-class>

---

您的hibernate JAR版本不兼容。 您还使用hibernate 3创建会话工厂，而所有hibernate JAR都是hibernate 4 JAR

我将向您推荐一个hibernate JAR列表，在您的情况下，这些JAR应该运行良好：

hibernate-annotations.jar
hibernate-c3p0-3.3.1.GA.jar
hibernate-cglib-repack-2.1_3.jar
hibernate-commons-annotations.jar
hibernate-core.jar 

---

看见这一定是classpath的问题。classpath，如何？？请不要介意，我不明白..您的类路径中可能有冲突版本的库（jar文件）。添加了jar列表。你能帮我检查一下吗？注释现在在Hibernate内核中。您不需要hibernate-commons-annotations-4.0.1.Final.jar。spring上下文使用hibernate3类，但类路径中有hibernate4。谢谢@Anvay。。我想这会有很大帮助。
