Can I have the META-INF folder into src/main/resources of a Spring command line application?
提问by AndreaNobili
I am working on a batch aplication implemented using Spring.
我正在研究使用 Spring 实现的批处理应用程序。
In this application I found the following structure:
在这个应用程序中，我发现了以下结构：
BATCH PROJECT
|
|
|------> src/main/java (containing the packages)
|
|------> src/main/resources
|
|----------> META-INF
|
|--------> applicationContext.xml (Spring configuration file)
So, as you can see in the previous schema, into the src/main/resourcesI found the META-INFfolder that contain the applicationContext.xmlfile that contains the Spring configuration (the beans definition).
因此，正如您在前面的模式中看到的，在src/main/resources 中，我找到了META-INF文件夹，其中包含applicationContext.xml文件，该文件包含 Spring 配置（bean 定义）。
This batch works fine but I have some doubt: can this place considered the correct place where to put the applicationContext.xmlfile ?
这批工作正常，但我有一些疑问：这个地方可以认为是放置applicationContext.xml文件的正确位置吗？
I always see the META-INFdirectory into web application (and not batch application as this) into the following folder that I don't have in this project (because it is not a web application):
我总是看到META-INF目录到 web 应用程序（而不是批处理应用程序）到我在这个项目中没有的以下文件夹中（因为它不是 web 应用程序）：
webapp
|
|_src
|
|_WebContent
|
|__WEB-INF
|
|__META-INF
Is it correct or can I do better?
这是正确的还是我可以做得更好？

Yes, this is fine. Here is a Spring Boot example that is doing precisely this.
是的，这很好。 这是一个 Spring Boot 示例，它正是这样做的。
META-INFis intended to contain the MANIFEST.MFfile and the servicessubdirectory related to the ServiceLoaderclass, but other frameworks, including Spring, use it as well.
META-INF旨在包含与类相关的MANIFEST.MF文件和services子目录ServiceLoader，但其他框架，包括 Spring，也使用它。

For Spring-batch it should be located under:
对于 Spring-batch，它应该位于：
META-INF/spring/batch/jobs/*.xml
META-INF/spring/batch/jobs/*.xml
So, in your case would be:
所以，在你的情况下将是：
WebContent/META-INF/spring/batch/jobs/applicationContext.xml
WebContent/META-INF/spring/batch/jobs/applicationContext.xml
