eclipse - 导入不同项目的resources=applicationContext.xml时eclipse中的Tomcat抛出FileNotFoundException

Question

我正在使用 Spring 和 Maven 项目。我在 mit-parent 下有项目 mit-webservices 和 mit-util 项目。

mit-webservices 正在使用 mit-utils。我正在从 mit-webservices 的 webapplicationContext.xml 中导入 mit-utils 的 applicationContext.xml，如下所示。

<import resource="classpath:mit/utils/shared/applicationContext.xml" />

但是当我在 Eclipse 中的 Tomcat 下运行 mit-webservices 时，我得到异常

在我的 mit-webservices 中有一些 junit 测试，我在其中加载 mit-webservices/webapplicationContext 文件并且它工作得很好。但是当我尝试在 tomcat 下部署 mit-webservices 时，它会抛出上述异常。

我还检查了 mit-webservices 的/lib 目录，发现 mit-utils.jar 确实存在。

每次部署前，我都会执行 mvn clean install 和 mvn eclipse:eclipse。 我认为 tomcat 在部署时无法在类路径中找到 mit-util，但我不知道为什么会这样。

我的WebApplicationContext.xml是

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

    <import resource="classpath:mit/utils/shared/applicationContext.xml" />

    <context:component-scan base-package="mit" />

</beans>

我在 mit-webservices 中的 web.xml 是

谢谢

尝试不同的建议解决方案后。 我在部署程序集的 eclipse 中发现“找不到条目:mit-jpa”。所以我安装了 Eclipse WTP Eclipse 插件。然后重新部署 tomcat，一切正常。
