Spring 找不到 Hibernate 映射文件

Question

因此，我正在试用 Enunciate，但在我的 servlet 启动时遇到了问题。由于某种原因，尽管该文件位于类路径中，并且所有内容都已正确指定，但 Spring 告诉我以下内容：

09-15@15:36:31 ERROR org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring-user-config.xml]: Invocation of init method failed; nested exception is java.io.FileNotFoundException: class path resource [WEB-INF/classes/resources/hibernate.xml] cannot be opened because it does not exist

结构是我有 applicationContext.xml （由 Enunciate 生成）、web.xml 和 spring-user-config .xml 位于 WEB-INF 内，然后是 hibernate.xml 位于 WEB-INF/classes/resources 中。

我已经尝试了所有方法，相对路径与绝对路径，使用“classpath：”，但我想不出任何其他原因为什么找不到它。

这是我的 spring-user-config.xml 文件中声明 sessionFactory bean 的地方：

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref local="dataSource"/>
        </property>
        <property name="hibernateProperties">
            <ref bean="exampleHibernateProperties"/>
        </property>
        <!-- Must references all OR mapping files. -->
        <property name="mappingResources" value="WEB-INF/classes/resources/hibernate.xml">
      </property>
</bean>

任何帮助让它工作的人都将不胜感激！

提前致谢。

Answer 1

尝试一下

<property name="mappingResources" value="resources/hibernate.xml" />

Answer 2

补充一下，我的 Eclipse 配置没有添加 WEB-INF/classes 目录，而且我不知道它正在此处搜索该文件。如果还有其他人在解决这个问题（这花了我几个小时的时间摆弄/谷歌搜索！），那么创建 WEB-INF/classes 目录并将所有 hibernate 资源文件复制到其中（或子目录，如在映射资源中指定）。

Answer 3

如果您使用任何 IDE，最好将 hibernate.xml 放在 Source 文件夹中。在运行时它会自动添加到类路径，在配置中您只需添加类路径：

<property name="mappingResources">
<value> classpath:hibernate.xml </value>
  </property>
