3.配置mybatis(sqlMapConfig.xml)
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 <configuration> 6 <!-- 设置别名 --> 7 <typeAliases> 8 <!-- 2. 指定扫描包，会把包内所有的类都设置别名，别名的名称就是类名，大小写不敏感 --> 9 <package name="com.itheima.springmvc.pojo" /> 10 </typeAliases> 11 12 </configuration>
4.配置SpringMVC
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 7 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 8 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 9 10 11 12 <!-- 扫描@Controler @Service --> 13 <context:component-scan base-package="com.itheima"/> 14 15 <!-- 处理器映射器 --> 16 <!-- <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/> --> 17 <!-- 处理器适配器 --> 18 <!-- <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/> --> 19 <!-- 注解驱动 --> 20 <mvc:annotation-driven conversion-service="conversionServiceFactoryBean"/> 21 22 <!-- 配置Conveter转换器 转换工厂 （日期、去掉前后空格）。。 --> 23 <bean id="conversionServiceFactoryBean" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"> 24 <!-- 配置 多个转换器--> 25 <property name="converters"> 26 <list> 27 <bean class="com.itheima.springmvc.conversion.DateConveter"/> 28 </list> 29 </property> 30 </bean> 31 32 <!-- 视图解释器 --> 33 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 34 <property name="prefix" value="/WEB-INF/jsp/"/> 35 <property name="suffix" value=".jsp"/> 36 </bean> 37 38 </beans>

6.总结
配置思路:
单独配置spring>单独配置mybatis>单独配置springMVC>mybatis与spring整合>web.xml配置
