第五步： beans.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?>  

<beans xmlns="http://www.springframework.org/schema/beans" 

xmlns:context="http://www.springframework.org/schema/context" 

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

xmlns:aop="http://www.springframework.org/schema/aop"  

    xmlns:util="http://www.springframework.org/schema/util"  

     xmlns:tx="http://www.springframework.org/schema/tx"  

    xsi:schemaLocation="  

    http://www.springframework.org/schema/context  

    http://www.springframework.org/schema/context/spring-context.xsd  

    http://www.springframework.org/schema/beans  

    http://www.springframework.org/schema/beans/spring-beans.xsd  

    http://www.springframework.org/schema/aop  

    http://www.springframework.org/schema/aop/spring-aop.xsd  

    http://www.springframework.org/schema/util  

    http://www.springframework.org/schema/util/spring-util.xsd

    http://www.springframework.org/schema/tx  

    http://www.springframework.org/schema/tx/spring-tx.xsd"> 

    

    <!-- 1、读取jdbc.properties配置文件-->

    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="locations" value="classpath:jdbc.properties"/>

</bean>

    

<!-- 2、配置 jdbc 数据源  dataSource-->

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

<property name="driverClassName" value="${driverClassName}"></property>

<property name="url" value="${url}"></property>

<property name="username" value="${username}"></property>

<property name="password" value="${password}"></property>

</bean>

<!-- 3、配置mybatis的sqlSessionFactory -->

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource"></property>

<!-- 引入mybatis配置文件 -->

<property name="configLocation" value="classpath:mybatis-config.xml"></property>

</bean>

<!-- 4、配置mybatis自动扫描sql映射文件/接口 -->

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

<property name="basePackage" value="com.hnqy.mapper"></property>

</bean>

<!-- 5、定义事务所在的bean -->

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<property name="dataSource" ref="dataSource"></property>

</bean>

<!-- 6、支持注解驱动的事务管理，指定事务管理器 -->

<tx:annotation-driven transaction-manager="transactionManager"/>

<!-- 7、aspectj支持自动代理实现AOP功能 -->

<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>

<!-- 8、定义事务的切面和切入点信息 -->

<!-- 定义事务的属性 -->

<tx:advice id="txAdvice" transaction-manager="transactionManager">

<tx:attributes>

<!-- read-only="true" 事务隔离级别最低，性能最高 -->

<tx:method name="list*" read-only="true"/> 

<tx:method name="find*" read-only="true"/>

   <tx:method name="get*" read-only="true"/>

   <tx:method name="select*" read-only="true"/>

 <!--   除了上面定义的方法之外，其他方法都要通过事务处理 -->

<tx:method name="*" propagation="REQUIRED" read-only="false"/>

</tx:attributes>

</tx:advice>

<!-- 定义事务所使用的切入点 -->

<aop:config>

<aop:pointcut expression="execution(* com.hnqy.service.impl.*.*(..))" id="pointcut"/>

<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>

</aop:config>

<!-- 定义spring扫描的包 -->

<context:component-scan base-package="com.hnqy.service.impl"></context:component-scan>

<context:component-scan base-package="com.hnqy.mapper"></context:component-scan>

</beans>

第六步：mybatis-config.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>

<!-- properties属性配置文件的引入 -->

<!-- setting设置，调整mybatis的运行行为 -->

<settings>

<!-- 是否开启自动驼峰命名规则（camel case）映射 -->

 <setting name="mapUnderscoreToCamelCase" value="true"/>

 <setting name="cacheEnabled" value="true"/>

 <setting name="lazyLoadingEnabled" value="true"/>

 <setting name="multipleResultSetsEnabled" value="true"/>

 <setting name="useColumnLabel" value="true"/>

 <setting name="useGeneratedKeys" value="false"/>

 <setting name="autoMappingBehavior" value="PARTIAL"/>

 <setting name="autoMappingUnknownColumnBehavior" value="WARNING"/>

 <setting name="defaultExecutorType" value="SIMPLE"/>

 <setting name="defaultStatementTimeout" value="25"/>

 <setting name="defaultFetchSize" value="100"/>

 <setting name="localCacheScope" value="SESSION"/>

 <setting name="safeRowBoundsEnabled" value="false"/>

 <setting name="jdbcTypeForNull" value="OTHER"/>

 <setting name="lazyLoadTriggerMethods" value="equals,clone,hashCode,toString"/>

</settings>

<!-- 类的别名 -->

  <typeAliases>

 <package name="com.hnqy.entity"/>

</typeAliases>

  

<!-- 设置要使用的数据库环境 -->

  

  <!-- 根据mybatis定义不同的数据库厂商标识 -->

   <!-- 映射的sql文件 -->

</configuration>

第七步： springmvc-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>  

<beans xmlns="http://www.springframework.org/schema/beans" 

xmlns:context="http://www.springframework.org/schema/context" 

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

    xmlns:util="http://www.springframework.org/schema/util"   

    xmlns:mvc="http://www.springframework.org/schema/mvc"   

    xmlns:tx="http://www.springframework.org/schema/tx"

    xsi:schemaLocation="  

    http://www.springframework.org/schema/context  

    http://www.springframework.org/schema/context/spring-context.xsd  

    http://www.springframework.org/schema/beans  

    http://www.springframework.org/schema/beans/spring-beans.xsd  

    http://www.springframework.org/schema/util  

    http://www.springframework.org/schema/util/spring-util.xsd

     http://www.springframework.org/schema/tx 

    http://www.springframework.org/schema/tx/spring-tx.xsd

    http://www.springframework.org/schema/mvc 

    http://www.springframework.org/schema/mvc/spring-mvc.xsd"> 

    

    <!-- 支持注解 -->

    <mvc:annotation-driven></mvc:annotation-driven>

    <!--定义注解要扫描的包  -->

    <context:component-scan base-package="com.hnqy.controller"></context:component-scan>

    <!-- 对静态资源的处理 -->

    <mvc:default-servlet-handler/>

    <!-- 配置视图解析器 -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/"/>

<property name="suffix" value=".jsp"/>

</bean>

<!-- 文件上传 -->

  <bean id="multipartResolver"

class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

<!-- 设置上传文件的最大尺寸为1MB -->

<property name="maxUploadSize">

<value>1048576</value>

</property>

</bean>

   </beans>

第八步：修改web.xml，设置应用启动加载spring、springmvc

 <!-- 应用启动加载spring配置文件 指定配置文件位置 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:beans.xml</param-value>

</context-param>

<!-- 配置spring的监听器 -->

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<!-- 针对post请求，防止取数据乱码 -->

<filter>

<filter-name>characterEncoding</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>characterEncoding</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<!-- springmvc 的核心分发器DispatcherServlet -->

<servlet>

<servlet-name>springmvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<!-- 初始化 DispatcherServlet 的时候，同时也会初始化spring容器，默认配置文件路径为/WEB-INF/<servlet-name>-servlet.xml。 -->

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:springmvc-servlet.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>springmvc</servlet-name>

<!-- “/” 为tomcat默认的请求处理器，所有请求都交给该servlet来处理。 默认为tomcat/conf/web.xml中配置的org.apache.catalina.servlets.DefaultServlet -->

<url-pattern>/</url-pattern>

</servlet-mapping>

第九步：创建相对应的包和类

第十步：测试
