SPRING框架概括——由外到内慢慢爬

Spring Module

1.核心容器 

 1.1 sping-core以及sping-beans.框架的核心组成，包括的IOC控制反转和依赖注入。提供以单例模式或原型的方式创建bean实例。

    1.2 spring-context,提供以框架的方式访问对象，有点像JNDI注册。

    1.3 spring-context-support,用来支持第三方包在spring中的集成，如Ehcache(for caching),Quartz(for scheduling)。

    1.4 spring-Expression,对jsp2.1的EL表达式语言做了扩展。

2.AOP and Instrumentation

   2.1 spring-aop模块提供了面向切面编程方式，允许你定义一个拦截函数或者切入点，目的是使得功能上完全不搭嘎的2个函数块解耦。

   2.2spring-aspect模块提供和AspectJ的集成。

   2.3 spring-instrument模块提供在应用程序服务器（如TOMCAT）中使用到的工具支持和类加载器的实现。spring-instrument-tomcat为

tomcat提供了Spring’s instrumentation 代理 .

3.Messaging：支持message方案的集成。

4.Data Access/Integration

  4.1  spring-jdbc 提供了JDBC抽象层，移除了复杂JDBC代码以及数据库厂商特殊错误代码的解析。

  4.2 spring-tx 模块支持实现特殊接口的类的事务管理能力。

  4.3  spring-orm 模块提供对object-relational mapping APIs(orm)的集成支持，包括JPA,JDO,Hibernate,以及MyIbatis.

  4.4  spring-oxm 模块提供一个支持Object/XML mapping实现的一个抽象层，比如JAXB, Castor, XMLBeans, JiBX and XStream.

  4.5  spring-jms 模块提供了收发短信的特性。Spring4.1开始，它支持与spring-messaging模块的集成.

5.Web

 Web层包括：spring-web, spring-webmvc, spring-websocket, and spring-webmvc-portlet.

6.Test

spring-test支持单元测试，支持加载spring上下文 ApplicationContext.
