SSM框架，是Spring + Spring MVC + MyBati

SSM framework is the abbreviation of Spring + Spring MVC + MyBatis. This is the current mainstream Java EE enterprise framework after SSH. It is suitable for building various large-scale enterprise application systems. <br>Spring is an open source framework. Spring is a lightweight Java development framework developed in 2003. In the book Expert One-On-One J2EE Development and Design, some concepts and prototypes elaborated by Rod Johnson are derived. It was created to solve the complexity of enterprise application development. Spring uses basic JavaBeans to accomplish things previously only possible with EJBs. However, the usefulness of Spring is not limited to server-side development. In terms of testability and loose coupling, any Java application can be inspired by Spring. In simple terms, Spring is a lightweight container inversion (IoC) and aspect-oriented (AOP) container framework. <br>Spring MVC belongs to the follow-up product of SpringFrameWork and has been integrated in Spring Web Flow. Spring MVC separates the roles of controller, model object, dispatcher, and handler object. This separation makes them easier to customize. <br>MyBatis was originally an open source project iBatis of apache. In 2010, this project was migrated from apache software foundation to google code and renamed as MyBatis. MyBatis is a Java-based persistence layer framework. The persistence layer framework provided by iBATIS includes SQL Maps and Data Access Objects (DAO). MyBatis eliminates the manual setting of almost all JDBC codes and parameters and the retrieval of result sets. MyBatis uses simple XML or annotations for configuration and original mapping, mapping interfaces and Java POJOs (Plain Old Java Objects, ordinary Java objects) to records in the database.

SSM框架，是Spring + Spring MVC + MyBatis的缩写，这个是继SSH之后，目前比较主流的Java EE企业级框架，适用于搭建各种大型的企业级应用系统。<br>Spring是一个开源框架，Spring是于2003 年研发的一个轻量级的Java 开发框架，在著作Expert One-On-One J2EE Development and Design中，由Rod Johnson 阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。然而，Spring的用处不仅限于服务器端的开发。在可测试性和松耦合的角度来说，任何Java应用都可以从Spring中获得启发。 简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。<br>Spring MVC属于SpringFrameWork的后续产品，已经融合在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。<br>MyBatis 本是apache的一个开源项目iBatis, 2010年这个项目由apache software foundation 迁移到了google code，并且改名为MyBatis 。MyBatis是一个基于Java的持久层框架。iBATIS提供的持久层框架包括SQL Maps和Data Access Objects（DAO）MyBatis 消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射，将接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java对象）映射成数据库中的记录。
