Question

我正在接管现有的Spring / JPA（w / hibernate）/ Maven项目，并尝试集成单元测试和集成测试。

该项目构建并运行良好，但是当我运行Maven Test来运行我的Spring集成测试时，我遇到了一个我无法弄清楚的错误：

org.hibernate.HibernateException: Could not find datasource

我有一种预感，它与我的POM配置有关。我的数据库上下文信息位于名为context.xml的文件中，之前的开发人员似乎已将此文件绑定到tomcat插件？这是否意味着数据库信息仅在tomcat上运行？运行？

</Context>

我可能会收到此错误的任何见解？

我也欢迎任何建议或示例代码，展示如何为这个多模块项目（包含子项目的父项目）配置Maven POM，以便它可以在每个模块中进行单元测试和集成测试。

Answer 1

context.xml是特定于tomcat的配置文件，因此如果您在Web容器外部运行测试，则不会使用它。解决方案是在弹簧配置文件中定义测试的数据源，该文件放在src/test/resources中（如果您遵循标准项目布局）。此文件夹仅用于测试类路径，因此不会干扰已部署的配置。

然后，您的测试必须使用此附加文件初始化spring应用程序上下文。
