spring 3.1设置配置文件

Question

我想在Spring 3.1中开始使用配置文件，并且发现问题。

在我休眠的XML文件我已经设置

<beans profile="test"> 

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


</beans> 

<beans profile="production"> 

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


</beans> 

而且在web.xml中我已经设置：

<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> 

，但是当我试图运行的应用程序，我有问题，该弹簧没有看到来自spring.properties文件的变量。

我应该设置别的东西吗？

UPDATE

休眠文件看起来是这样的：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </beans>

我想原因是，既然你想这在你的根应用上下文，装起来通过的ContextLoaderListener，指定配置文件的方式不是通过DispatcherServlet的初始参数，而是ServletContext的初始参数，这种方式在你的web.xml文件中：

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