Question

我正在使用hibernate 3.2.7和spring 3.2.8。错误是***

**“：在ServletContext资源[/WEB-INF/spring-servlet.xml]中定义名为'sessionFactory'的bean时出错：调用 init方法失败;嵌套异常是java.io.FileNotFoundException： ServletContext资源[/resources/hibernate.cfg.xml]不能已解析为URL，因为它不存在“。

我尝试将hibernate.cfg.xml放在src，webinf和classpath中，但它仍然没有找到它。这是我的错误堆栈跟踪：

我的spring-servlet是：

<bean
  class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="prefix">
    <value>/</value>
  </property>
  <property name="suffix">
    <value>.xhtml</value>
  </property>
</bean>

<bean id="propertyConfigurer"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
    p:location="/WEB-INF/jdbc.properties" />

<bean id="dataSource"
    class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
    p:driverClassName="${jdbc.driverClassName}"
    p:url="${jdbc.databaseurl}" p:username="${jdbc.username}"
    p:password="${jdbc.password}" />


<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation">
    <value>resources/hibernate.cfg.xml</value>
    </property>
    <property name="configurationClass">
        <value>org.hibernate.cfg.AnnotationConfiguration</value>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">${jdbc.dialect}</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.connection.SetBigStringTryClob">true</prop>
            <prop key="hibernate.jdbc.batch_size">0</prop>
            <prop key="hibernate.jdbc.batch_size">0</prop>
        </props>
    </property>
</bean>
<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

    <!-- one of the properties available; the maximum file size in bytes -->
    <property name="maxUploadSize" value="10000000" />
</bean>
<tx:annotation-driven />

<bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">

</bean>

Answer 1

configLocation的属性LocalSessionFactoryBean的类型为Resource，您可以指定带前缀的资源类型，例如：

classpath:resources/hibernate.cfg.xml

默认情况下，在ServletContext中，如果不指定前缀，则资源使用类ServletContextResource。来自Spring Documentation：

5.3.4 ServletContextResource

这是ServletContext资源的Resource实现，用于解释相关Web应用程序根目录中的相对路径。

这始终支持流访问和URL访问，但仅在扩展Web应用程序存档且资源实际位于文件系统上时才允许java.io.File访问。它是否在这样的文件系统上扩展，或者直接从JAR或其他地方（如DB）访问（可以想象）实际上都依赖于Servlet容器。

然后，您需要输入前缀或将资源放在应用程序的根目录中。

您可以在弹簧文档中查看Resources中的所有资源。
