我有一个正在使用的数据库项目spring。为此，我在src/META-INF/spring/（数据库项目）中有两个重要文件

第一个是cmn-dao-spring.xml。另一个是database.properties。

在我的tomcat webapp项目中，我能够使用该代码加载所有需要的上下文文件：

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
              classpath*:/META-INF/spring/*.xml  
    </param-value>
  </context-param>

问题是database.properties未加载。如果我将xml更改为此：

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
              classpath*:/META-INF/spring/*  
    </param-value>
  </context-param>

我得到异常：

Caused by: org.xml.sax.SAXParseException: Content is not allowed in prolog.

因为properties无效xml。我的tomcat启动失败。

如何database.properties在我的Webapp中包含来自cmn-dao项目的？

编辑

那就是我的cmn-dao.xml：

用于cmn-dao的JUnit绝对正确，占位符也起作用。在tomcat项目中，我通过添加了相关项目Deployment Assembly。
