Question

我正在尝试使用NetBeans开发环境在Windows 7 x66上设置新的Spring / Hibernate / Apache 7 / MySQL。

所有必需的Spring Framework＆amp; Hibernate JARS已经由NetBeans预先打包。

我收到以下错误：

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener 

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from URL location [classpath:./WEB-INF/hibernate-context.xml]
Offending resource: ServletContext resource [/WEB-INF/applicationContext.xml];

这表明我的applicationContext.xml无法使用以下标记找到我的hibernate-context.xml：

方法1＃

<import resource="hibernate-context.xml" />

方法＃2

<import resource="classpath:./WEB-INF/hibernate-context.xml" />

我的hibernate-context.xml实际上存在于“../ WEB-INF / hibernate-context.xml”

所以这似乎是某种类的Spring类路径问题，我在环境变量中设置了类路径，但仍然出现错误。

请告诉我一个干净的解决方案。

的web.xml：

您通常拥有Web.xml中提到的application-context.xml。这是所有spring上下文文件的主配置。

application-context.xml依次包含导入的单独上下文xml文件;就像你做的那样。

这通常是采取的方法。

如果您已经有固定数量的上下文文件，并且您没有看到它们发生变化，您可以这样做：

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        WEB-INF/applicationContext.xml,
        classpath:hibernate-context.xml
    </param-value>
  </context-param>

只要上下文文件位于类路径中;你可以使用“classpath：”，它应该可以正常工作。
