**1、dao层**  
　　**1.1、必须数据：**  
　　　　　　　pojo（java实体）、mapper接口（dao接口）、sql映射文件（翻译为jdbc中的statement）  
　　**1.2、配置文件：**  
　　　　　　　mybatis核心配置文件：[SqlMapConfig.xml][]  
　　　　　　　　　　自定义别名  
　　　　　　　spring整合mybatis配置文件：[applicationContext-dao.xml][]  
　　　　　　　　　数据源  
　　　　　　　　　会化工厂  
　　　　　　　　　mapper扫描（加载dao）  
　　　　　　　其他配置：  
　　　　　　　　　数据库信息：[db.properties][]  
　　　　　　　　　日志信息：[log4j.properties][]  
**2、service层**  
　　**2.1、配置文件：**  
　　　　　　　注解扫描：@service（加载service）[applicationContext-service.xml][]  
　　　　　　　事务配置： [ApplicationContext-trans.xml][]  
**3、controller层**  
　　**3.1、配置文件：** [springMVC.xml][]  
　　　　　　　注解扫描：@controller（加载controller）  
　　　　　　　注解驱动：自动加载最新的处理器映射器、处理器适配器  
　　　　　　　视图解析器：  
　　　　　　　自定义类型转化器：(挂载于注解驱动)  
　　　　　　　文件上传解析器：  
　　　　　　　json格式数据解析器：（若没有配置注解驱动，则需要显示的在处理器适配器挂载）  
　　　　　　　全局异常处理器：  
　　　　　　　自定义拦截器：  
　　　　　　　静态资源放行：  
　　　　　　　  
**4、web.xml** [web.xml][]  
　　**4.1、spring监听器**  
　　**4.2、springMVC前端控制器**  
　　**4.3、post中文乱码请求**
