java - 在spring mvc maven项目中添加外部项目

Question

我是 Spring MVC 的新手。我正在尝试将我的核心 Maven 项目添加到 Spring MVC Maven 项目中。它构建成功，我可以在“target\project.war\WEB-INF\lib”中看到相应的 jar 文件，但它在 glassfish 控制台上抛出错误。

Severe: Exception while deploying the app

我无法添加任何 Maven 项目或 jar 文件。很可能我在添加依赖项方面没有做得正确。如果有人可以帮助我的话。提前致谢。

下面是我的 POM 文件。

Answer 1

我之前使用过的一种方法是创建一个包含两个项目的主项目，主项目应该具有主 POM 文件，该 POM 文件在所有子项目之间共享依赖关系，并且每个项目都应该具有他们自己的 POM 配置。然后，您可以在 spring MVC 项目 POM 中导入您的第二个子项目。更多详情:

您还可以使用称为多模块项目的东西:
