Where to put Spring applicationContext.xml in a non-web application?
提问by itun
I am creating an application which uses Spring beans and I need to initialize ApplicationContextfrom xml. As it is not a server application, it doesn't have WEB-INFfolder.So, where I should put the xmlfile?
我正在创建一个使用 Spring bean 的应用程序，我需要ApplicationContext从xml. 因为它不是服务器应用程序，所以它没有文件夹。WEB-INF所以，我应该把xml文件放在哪里？

The spring documentation for this topic is a little overwhelming at first. A handy starting point in the spring documentation for application context config is here
这个主题的 spring 文档起初有点让人不知所措。应用程序上下文配置的 spring 文档中的一个方便的起点是here
A file system xml application contextis probably the easiest to start with. So:
一个文件系统的XML应用程序环境可能是最容易下手。所以：
ApplicationContext appCtx =
new FileSystemXmlApplicationContext("/path/to/springconfig.xml");
Use ClassPathApplicationContextif you have the xml configuration in your application class path. In this example it might be a springconfig.xml under a project directory src/config/springconfig.xml.
使用ClassPathApplicationContext，如果你在你的应用程序类路径中的XML配置。在此示例中，它可能是项目目录 src/config/springconfig.xml 下的 springconfig.xml。
ApplicationContext appCtx =
new ClassPathXmlApplicationContext("config/springconfig.xml");
If you are unsure where your springconfig.xml ends up after you have built your application, you can use the following command to list the contents of your jar:
如果在构建应用程序后不确定 springconfig.xml 的最终位置，可以使用以下命令列出 jar 的内容：
jar -tvf myapp.jar
For a default eclipse java project, the project-home/bindirectory is the start of the classpath.
对于默认的 eclipse java 项目，project-home/bin目录是类路径的开始。

Use ClassPathXmlApplicationContext:
使用ClassPathXmlApplicationContext：
ApplicationContext ctx =
new ClassPathXmlApplicationContext("applicationContext.xml");
Or consider migrating to @Configuration:
或者考虑迁移到@Configuration：
ApplicationContext ctx =
new AnnotationConfigApplicationContext(AppConfig.class);
where AppConfigis annotated with @Configurationand no XML is needed.
whereAppConfig被注释@Configuration并且不需要 XML。

Check this example Spring Setter Injection
If the XML is in the applications classpath then use like this
如果 XML 在应用程序类路径中，则像这样使用
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
Otherwise if the XML is in File system then use
否则，如果 XML 在文件系统中，则使用
ApplicationContext context = new FileSystemXmlApplicationContext("beans.xml");
