我想在 Spring 3.1 中开始使用配置文件，但我发现了一个问题。

在我设置的休眠 xml 文件中

<beans profile="test">

    <context:property-placeholder location="/WEB-INF/springtest.properties" />


</beans>

<beans profile="production">

    <context:property-placeholder location="/WEB-INF/spring.properties" />


</beans>

在 web.xml 我已经设置：

<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <init-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>production</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

但是当我尝试运行应用程序时，我遇到了问题，spring 看不到spring.properties文件中的变量。

我应该设置其他东西吗？

更新

休眠文件如下所示：

我认为原因是，由于您希望在根应用程序上下文中通过 ContextLoaderListener 加载，因此指定配置文件的方式不是通过 DispatcherServlet 的 init 参数，而是通过 ServletContext 的 init 参数，这样在您的 web.xml 文件中：

<context-param>
    <param-name>spring.profiles.active</param-name>
    <param-value>production</param-value>
</context-param>
