spring - Using spring in a stand alone jar for dependency injectection

Question

Am a total beginner with spring framework and trying to know if it even fits my use case, before investing time learning it.

I'm responsible for a stand alone java project(used as a jar by a server) which basically serves requests from a server, and in turn makes service calls to various internal services. This standalone java project, currently has all of its service calls hard coded. I want to use Spring to inject dependencies so I can make this stuff testable.

I have no idea how spring works. Does it even hold for standalone jars or is it only for 'running applications'?

If I make my standalone project 'spring enabled', when the server uses my jar, will it automagically work by creating beans or is there some requirement from the server side?

简而言之，是的，您可以在独立的 jar 应用程序（“控制台应用程序”，如果您愿意的话）中使用 Spring，我们一直在工作。您只需要在应用程序启动时自己创建 ApplicationContext，请参见此处的示例：http: //www.devdaily.com/blog/post/java/load-spring-application-context-file-java-swing-application

这只是我直接从 Google 中提取的一个示例，可能还有很多其他示例。不过，您确实需要至少阅读Spring 文档中的基础知识才能开始使用，否则您可能很快就会碰壁。
