【问题描述】：

您好，我正在开发一个 Spring MVC 休息服务，需要一个模块化项目。为此，我有 3 个 java 应用程序项目（接口、实现接口和 bean 对象），但我不能将其包含在我的 Spring 项目中。我正在尝试导入每个项目的 xml，但这不起作用。

标签： java xml maven spring-mvc

【解决方案1】：

XML 上下文声明文件路径应该在 <import> 标记中的标准化字符串表示之后提及，即项目分隔符应该是 /（斜杠）而不是.（句号）。

<import resource="classpath*:cl/securityAuthentication/business/business-context.xml"></import>
<import resource="classpath*:cl/securityAuthentication/beans/beans-context.xml"></import>
