Spring框架下面各个部分是怎么样一种关系，他们都有那些职责？

Question

如同IDEA之中，显示的Spring框架下面有
SpringBatch,
SpringData JPA,
Spring integration,
Spring MVC,
Spring Security,
Spring Web Flow,
Spring Web Services，等
他们之间是什么关系，和Spring框架之间又有什么关系？

如果创建一个最简单的Hello Spring程序我应该勾选哪个？

Answer 1

勾选Spring MVC,上述的区别，你从字面意思就可以看出来，spring MVC是做MVC框架的，web service做接口的，现在都用restful api了，就不用webservice了，其他的很少使用，你可以在spring官网上查到：spring.io

Spring Batch provides reusable functions that are essential in processing large volumes of records, including logging/tracing, transaction management, job processing statistics, job restart, skip, and resource management. It also provides more advanced technical services and features that will enable extremely high-volume and high performance batch jobs through optimization and partitioning techniques. Simple as well as complex, high-volume batch jobs can leverage the framework in a highly scalable manner to process significant volumes of information.

Spring Web Flow builds on Spring MVC and allows implementing the "flows" of a web application. A flow encapsulates a sequence of steps that guide a user through the execution of some business task. It spans multiple HTTP requests, has state, deals with transactional data, is reusable, and may be dynamic and long-running in nature..

Answer 2

Spring framework是分模块的，用一张spring的官方文档上的图来说明

http://docs.spring.io/spring/...

你图上的这些项目都是基于这些模块开发的Spring的子项目，比如说Spring MVC是针对web开发的，那么它里面用到的模块有Spring web等，还有一些Spring的核心模块。

你只是写一个Hello world的话，用Spring Core Container下的模块就行了。
