这取决于您打算如何部署和运行此项目。对于分层多模块项目，我们通常在模块中包含一个log4j配置文件，其中包含 main 方法，该方法将启动该程序。

It depends on how you intend to deploy and run this project. For hierarchical multi-module projects, we generally included a log4j config file in the module with the main method that would launch the program.

例如，考虑使用项目 client 和 server 的简化设置，它们都依赖于 framework 用于公共类（RMI接口，域对象等）。客户端作为桌面应用程序运行，具有自己的主入口点，因此在src / main / resources下获取自己的log4j.properties文件。服务器模块也是如此。然而，框架不获取属性文件 - 其记录器调用将由其调用模块配置的任何记录器处理。

For example, consider a simplified setup with projects client and server which both rely on framework for common classes (RMI interfaces, domain objects, etc). Client is run as a desktop application, has its own main entry point, and thus gets its own log4j.properties file under src/main/resources. So does the server module. Framework, however, does not get a properties file -- its logger calls will be handled by whichever loggers have been configured by its calling module.
