ssm框架搭建的步骤：
1.新建一个maven项目
2.导入相应的jar包
3.引入Mybatis的核心配置文件
-->mybatis-config.xml(该文件主要配置一些如：缓存，驼峰命名，分页插件等，其他数据源、事务交给spring)
4.引入Mybtais的映射文件
-->mapper
5.引入Spring的配置文件
-->applicationContext.xml(主要配置：数据源、事务、sqlsessionfactory)
6.引入SPringMVC的配置文件
-->springmvc-config.xml(配置controller注解，视图解析 )
7.修改web.xml配置Spring的容器加载的listener +SpringMVC的DispatcherServelt+中文乱码解决器
8.项目部署和测试
pom文件的配置（导入相关依赖）

配置文件的配置
引入mybatis配置文件（mybatis-config.xml）
由于mybatis和spring整合后，所以一些数据源交由spring管理
而该配置文件用于配置一些，驼峰式命名，分页和别名的配置 ```xml <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
#### mapper文件写法
```xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.jt.manage.mapper.ItemMapper">
<!-- 商品的列表查询，按照修改时间倒序 -->
<select id="queryItemList" resultType="Item">
SELECT * FROM tb_item ORDER BY updated desc
</select>
</mapper>
引入spring的配置文件（applicationContext.xml）
**该文件是speing容器的配置文件，整合了mybatis和springmvc两个框架;**
**主要配置的内容有：**
**包扫描器：（service和dao层的扫描）， 配置数据源（数据连接），**
**SqlSessionFactory配置，整合mybatis；mapper文件的映射，和mapper接口的扫描， 事务管理**

//获取上下文对象

//ItemMapper item = ac.getBean(ItemMapper.class);
//List<Item> list = item.findAll();
