      <groupId>org.mybatis</groupId>
      <artifactId>mybatis-spring</artifactId>
      <version>1.3.2</version>
    </dependency>    

第二步：建表，实体，dao，mapper配置文件，service

第三步：spring整合mybtais spring的配置文件

1.包扫描

2.数据源

3.sqlsessionFactory

4.批量创建dao

5.事务管理器

6.开启注解式事务驱动

<!--1.包扫描-->
<context:component-scan base-package="com.baizhi.service"></context:component-scan>
<!--2.数据源-->
 <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="username" value="root"></property>
        <property name="password" value="root"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/test"></property>
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
    </bean>
    <!--3.sqlsessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="typeAliasesPackage" value="com.baizhi.entity"></property>
        <property name="mapperLocations" value="classpath:com/baizhi/mapper/*.xml"></property>
    </bean>
    <!--4.批量创建dao-->
    <bean id="configurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.baizhi.dao"></property>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>
    <!--5.事务管理器-->
    <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--6.开启注解式事务驱动-->
    <tx:annotation-driven transaction-manager="dataSourceTransactionManager"></tx:annotation-driven>

第四步：开发controller

第五步：配置springmvc的配置文件

1.包扫描

2.开启两大组件的注解式驱动

3.配置视图解析器

4.静态资源处理

<!--1.包扫描-->
<context:component-scan base-package="com.baizhi.controller"></context:component-scan>
<!--2.开启两大组件的注解式驱动-->
<mvc:annotation-driven></mvc:annotation-driven>
<!--3.配置视图解析器-->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    <!--4.静态资源处理-->
    <mvc:default-servlet-handler></mvc:default-servlet-handler>

第六步：配置web.xml

1.配置监听器，启动工厂指定的配置文件

2.配置springmvc的核心前端控制器DispatcherServlet

3.配置编码过滤器，处理post请求的乱码

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:spring.xml</param-value>
</context-param>
<filter>
  <filter-name>characterEncodingFilter</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <init-param>
    <param-name>encoding</param-name>
    <param-value>utf-8</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>characterEncodingFilter</filter-name>
  <url-pattern>/ *</url-pattern>
</filter-mapping>
<!--配置监听器-->
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--配置springmvc的前端核心控制器-->
<servlet>
  <servlet-name>dispatcherServlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:springmvc.xml</param-value>
  </init-param>
</servlet>
<servlet-mapping>
  <servlet-name>dispatcherServlet</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

第七步：测试
