SSM整合配置文件详解

学向勤中得，萤窗万卷书。这篇文章主要讲述SSM整合配置文件详解相关的知识，希望能为你提供帮助。
一、文件内容列表 1.1 mybatis 核心配置文件（可省略）

别名配置< typeAliases>
可以配置实体类的别名
【SSM整合配置文件详解】设置配置< settings>
可以对mybatis进行相关设置

映射配置文件

常规映射配置文件

1.2 spring 配置文件

spring相关
1. 加载数据库配置文件
2. 配置数据源 dataSource
3. 配置 SqlSession 工厂类【可以指定 Mybatis 核心配置文件和映射配置文件路径、指定别名】
4. 开启 dao 层的mapper接口扫描【配置一个扫描的类】
mybatis整合相关
1. 开启Ioc注解扫描，扫描除控制层外的类【需要配置扫描包】
2. 开启Aop注解扫面
3. 开启事务注解扫描
4. 配置 spring 平台事务管理器【需要注入数据源】

1.3 springmvc 配置文件

启用注解扫描器，扫描被控制层的类【配置扫描的包】
加载映射注解驱动
配置处理静态资源的驱动
配置拦截器
配置文件上传解析器
配置视图解析器
配置视图控制器 < mvc: view-controller>

1.4 其它配置文件数据库连接配置文件

数据库连接的基本配置【驱动、url、用户名、密码】

web项目配置文件

配置首页【欢迎页面】
开启 Spring < context-param> 【加载spring配置文件】
配置加载Spring文件的监听器
开启SpringMVC 【配置DispatcherServlet】
配置SpringMVC 字符编码过滤器【要在所有过滤器的最前面】
配置请求方式过滤器【RESTful风格使用】

二、实例 web.xml
