如果删除了文件，最好：clean package一下。
创建包
java目录
com.itheima
- controller
- service
- mapper
- UserMapper 接口
- domain
resource目录
- com/itheima/mapper/UserMapper.xml
注解：
-controller 的类中添加@Controller注解
-serviceImpl 中的实现类 ： @Service @Transactional
-mapper 的接口： @Repository
有关动态sql的编写：
if test=" 必须是String类型的数据 "
直接返回对象：会自动的转换为json，mvc的注解驱动会自动的配置的
有关拼接sql的注意点：
<if test=' start!="0" '> 外面是单引号，里面是双引号。 不容易出错。
limit ${start},${pageSize}
</if>
使用注解开发写sql
applicationContext-dao.xml
<!-- sqlsessionFactoryBean -->
<bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory">
<property name="dataSource" ref="dataSource"/>
<property name="typeAliasesPackage" value="com.boy2.pojo"/>
<!-- 这里将mybatis的核心配置文件加载进入。 -->
<property name="configLocation" value="classpath:sqlMapConfig.xml"/>
</bean>
sqlMapConfig.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">
<configuration>
<mappers>
<!-- 接口所在的包 -->
<package name="com.boy2.mapper"/>
</mappers>
</configuration>
在applicationContext-dao.xml中导入外部的jdbc.properties文件
切记要以：jdbc. 来开头。 不写可能会出错。吃过亏。
