java - 无法打开类路径资源 [default/jdbc.properties]，因为它不存在

Question

我认为我在继承的一个大型 Maven 多模式项目中取得了良好的进展。在 Tomcat 和 JAVA 项目的所有方面，我都是一个完全的初学者，所以请原谅我的天真。我相信我需要知道如何定义我的 JDBC 属性配置的位置，但老实说我不知道​​从哪里开始。

我正在尝试使用“mvn tomcat7:run”通过终端运行我的项目并收到如下所述的严重错误。

具体错误原因:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'eu.digient.billfold.support.dao.properties': Invocation of init method failed; nested exception is java.io.FileNotFoundException: class path resource [default/jdbc.properties] cannot be opened because it does not exist

我在 Maven 项目中的许多 .IML 文件中找到了这个字符串，语法是什么意思，它在哪里寻找配置？

 <util:properties id="eu.digient.billfold.support.dao.properties"
                 location="classpath:#{systemProperties['configProfile']?:'default'}/jdbc.properties" />

关于 JBDC 配置的任何提示和建议都很棒，我知道它用于定义数据库连接详细信息。在这种情况下，与 Hibernate for JAVA 的连接对我来说是全新的。

(除了通过 block 引用之外，我不确定如何将它作为 block 添加到下面，所以如果我错过了一种更具可读性的方法？)

完整的终端错误输出:
