Question

我正在使用spring和hibernate开发一个应用程序，所以我的应用程序内容文件遇到了问题：

 <beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans 


    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<!-- Database Configuration -->
<import resource="../database/dataSource.xml" />
<import resource="../database/hibernate.cfg.xml" /> 

<!-- Beans Declaration -->
 <import resource="../beans/databeans.xml" />
    </beans>

我的问题是：

配置文件中存在问题。错误很明显，它说XML解析器无法解析文件。在eclipse中打开文件，右键单击并选择“validate xml”选项并修复问题。

希望这有用！
