搭建SSM框架环境（spring整合mybatis整合springMVC）

1、SSM：spring+mybatis+springmvc

2、springMVC：视图层，界面层，负责接收请求，显示处理结果；

spring：业务层，管理service、dao，工具类对象的；

mybatis：持久层，访问数据库的；

用户发起请求---------springmvc接收----spring中的service对象-----mybatis处理数据

3、实现步骤：

《1》创建maven web项目

《2》加入依赖

springmvc，spring，mybatis三个框架的依赖，Jackson依赖，mysql驱动，druid连接池，jsp，servlet依赖

《3》写web.xml文件

1、注册DispatcherServlet，目的：创建springmvc的容器对象,才能创建controller类对象；创建的是servlet，才能接收用户的请求；

2、注册spring的监听器：contextloaderlistener，目的：创建spring的容器对象，才能创建service，dao等对象

3、注册字符集过滤器，解决post请求乱码的问题

《4》、创建包： controller包，service，dao，实体类包

《5》、写springmvc、spring、mybatis的配置文件

resources：springmvc配置文件

spring配置文件

mybatis配置文件

数据库的属性配置文件

《6》、写java代码

《7》、写jsp页面

4、具体环境配置代码

pom.xml（ssm框架需要的依赖和resources插件）
