今天完成的事情:
整合springMVC,mybatis

<!-- 配置SpringMVC -->
<!-- 1.开启SpringMVC注解模式 -->
<!-- 简化配置: (1)自动注册DefaultAnootationHandlerMapping,AnotationMethodHandlerAdapter (2)提供一些列:数据绑定,数字和日期的format @NumberFormat, @DateTimeFormat, xml,json默认读写支持 -->
<mvc:annotation-driven />
<!-- 2.静态资源默认servlet配置 (1)加入对静态资源的处理:js,gif,png (2)允许使用"/"做整体映射 -->
<mvc:default-servlet-handler/>
<!-- 3.配置jsp 显示ViewResolver -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 4.扫描web相关的bean -->

<!-- 扫描service包下所有使用注解的类型 -->
<context:component-scan base-package="com.student" />
<!-- 配置事务管理器 -->

<!-- 注入数据库连接池 -->

<!-- 配置基于注解的声明式事务 -->

<!-- 如果是用mvn命令生成的xml,需要修改servlet版本为3.1 -->
<!-- 配置DispatcherServlet -->
<servlet>
<servlet-name>seckill-dispatcher</servlet-name>

<!-- 配置springMVC需要加载的配置文件 spring-dao.xml,spring-service.xml,spring-web.xml Mybatis - > spring -> springmvc -->

<!-- 配置整合mybatis过程 -->
<!-- 1.配置数据库相关参数properties的属性:${url} -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 2.数据库连接池 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<!-- 配置连接池属性 -->

<!-- 关闭连接后不自动commit -->
<!--<property name="defaultAutoCommit" value="false"/>-->
<!-- 获取连接超时时间 -->
<!--<property name="loginTimeout" value="1000"/>-->
<!-- 当获取连接失败重连次数 -->
<!--<property name="defaultTransactionIsolation" value="2"/>-->
</bean>
<!-- 3.配置SqlSessionFactory对象 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入数据库连接池 -->
<property name="dataSource" ref="dataSource"/>
<!-- 配置mybatis全局配置文件:mybatis-config.xml -->
<property name="configLocation" value="classpath:mybatis-config.xml"/>
<!-- 扫描sql配置文件:mapper需要的xml文件 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
</bean>
<!-- 4.配置扫描dao接口包,动态实现dao接口,注入到spring的容器中 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactoryBeanName" value="sqlSeesionFactory"/>
<!-- 给出需要扫描dao接口包 -->

明天计划的事情:
继续整合
遇到的问题:
层级未曾分辨清楚,配置文件的扫描还要继续,这个配置有点绕,明天画图分解下
