我想知道为什么我的dataSoure无法找到？

Question

我想改变我的数据源动态的，所以我用弹簧3.1和Profile属性，这是我的应用程序上下文XML的一部分：

<?xml version="1.0" encoding="UTF-8" ?>

    </beans> 
</beans> 

我web.xml设置spring.profiles.default：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 

    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>classpath:applicationContext.xml,classpath:applicationContext-dao.xml,classpath:sqlMapConfig.xml</param-value> 
    </context-param> 

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

    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 
    <servlet> 
     <servlet-name>hello</servlet-name> 
     <servlet-class>test.HelloWorldServlet</servlet-class> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>hello</servlet-name> 
     <url-pattern>/hello</url-pattern> 
    </servlet-mapping> 

</web-app> 

但总会得到一个例外：

nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSource' is defined 

我不熟悉春天，并试图服务器时间，但也不能正常工作，可以在任何一个可以帮我解决这个问题？ 谢谢。

加入我的全部应用程序上下文XML和web.xml。

我觉得你的背景下PARAM应该

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

变化默认到活跃
