使用Spring MVC和Hibernate与JPA的ContextLoaderListener错误

标签： spring hibernate spring-mvc jpa

我研究并尝试了有关此问题的其他问题的解决方案，但没有成功（例如下面的主题）

java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

我是.NET开发人员，尝试使用我当前的项目切换到JAVA。我使用JPA作为我的数据存储库层（使用Maven），使用Hibernate配置Spring MVC项目。我已经配置了所需的文件（web.xml，pom文件，jpa上下文文件等）。但是，一旦将其部署到TomCat Apache服务器，我就会收到一条错误消息，指出配置应用程序监听器时出现问题。

我尝试了一些步骤：

  1. 我的Spring Maven依赖项列为编译而非提供
  2. 我在构建路径中包含了Maven依赖项
  3. 我使用Maven菜单更新了项目
  4. 我检查过以确保Spring依赖关系包含在依赖关系层次结构
    5. 中 你能帮助我吗？提前谢谢！

    完整错误：

    SEVERE: Error configuring application listener of class org.springframework.web.context.contextLoaderListener java.lang.ClassNotFoundException: org.springframework.web.context.contextLoaderListener at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1702) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1547) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:532) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:514) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:142) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4854) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5434) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1559) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1549) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

    这似乎是一个相当常见的错误 - 然而，到目前为止提出的解决方案还没有奏效。

答案 0 :(得分：3)

我认为你的web.xml定义中有一个拼写错误。它必须是

org.springframework.web.context.ContextLoaderListener

资本 C

基本上，这个...... 

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

必须是

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