1.新建maven项目如下图：

2.在pom.xml中增加需要的包

 <properties>

       <finalName>base</finalName>
       <mybatis-version>3.3.0</mybatis-version>
      <mybatis-spring-version>1.2.3</mybatis-spring-version>
 </properties>

       </dependency>
 </dependencies>

3.在web.xml中配置springmvc拦截器

<servlet> 
       <servlet-name>mvc-dispatcher</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
 </servlet>
 <servlet-mapping>
       <servlet-name>mvc-dispatcher</servlet-name>
       <url-pattern>/</url-pattern>
 </servlet-mapping>

4.配置数据源

在resources包下新建一个applicationContext-dao.xml文件，具体配置如下：

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
       <property name="driverClassName" value="com.mysql.jdbc.Driver" />
       <property name="url" value="${url}" />  读取 mysql.properties 数据
       <property name="username" value="${username}" />
       <property name="password" value="${password}" />
 </bean>

 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  配置sessionFactory 
       <property name="dataSource" ref="dataSource" />
       <property name="mapperLocations" value="classpath:com/ahpome/company/*mapper/**/*.xml" /> 对应包下的xml文件方便映射
       <property name="typeAliasesPackage" value="com.ahpome.pojo" />
       <property name="plugins">
            <list> 配置数据库  这里配置的是mysql MySSLDialect ，Oracle OracleDialect 表示是Oracle
                 <bean class="com.github.miemiedev.mybatis.paginator.OffsetLimitInterceptor"> 
                    <property name="dialectClass" value="com.github.miemiedev.mybatis.paginator.dialect.MySQLDialect"></property>
                 </bean>
            </list>
       </property>
 </bean>
 <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"> 
       <constructor-arg index="0" ref="sqlSessionFactory" />
 </bean>
 <bean id="baseDao" class="common.mybaits.DynamicSqlSessionDaoSupport"
       abstract="true" lazy-init="true">
       <property name="targetSqlSessionFactorys">
            <map>
                 <entry key="mainDataSource" value-ref="sqlSessionFactory" />
                 <entry key="otherDataSource" value-ref="sqlSessionFactory" />
            </map>
       </property>
       <property name="defaultTargetSqlSessionFactory" ref="sqlSessionFactory" />
 </bean>
 <bean id="transactionManager"
      class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
       <property name="dataSource" ref="dataSource" />
 </bean>
         使用aop横向切面的方式 配置事务
 <tx:advice id="txAdvice" transaction-manager="transactionManager">
       <tx:attributes>
            <tx:method name="add*" propagation="REQUIRED" rollback-for="Exception" />
            <tx:method name="save*" propagation="REQUIRED"  rollback-for="Exception" />
            <tx:method name="del*" propagation="REQUIRED" rollback-for="Exception" />
            <tx:method name="update*" propagation="REQUIRED" rollback-for="Exception" />
            <tx:method name="modify*" propagation="REQUIRED"  rollback-for="Exception" />
            <tx:method name="find*" propagation="REQUIRED" />
            <tx:method name="get*" propagation="REQUIRED" />
            <tx:method name="apply*" propagation="REQUIRED" />
            <tx:method name="*" propagation="REQUIRED" read-only="true" />
       </tx:attributes>
 </tx:advice>
   
 <aop:config>
       <aop:pointcut id="interceptorPointCuts" expression="execution(* com.ahpome.company.services..*.*(..))" />
       <aop:advisor advice-ref="txAdvice" pointcut-ref="interceptorPointCuts" />
 </aop:config>

5.配置SpringMVC

需要被扫描的包，如果不配置springmvc 将无法找到使用@controller注解的类 这里相当于servlet
<context:component-scan base-package="com.ahpome.company.controller"/>
 <mvc:resources location="/WEB-INF/resoures/" mapping="/resoures/**"/>配置静态资源访问
 <mvc:annotation-driven>
    <mvc:message-converters register-defaults="true">
        <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
            <property name="supportedMediaTypes">
                <list>
                    <value>text/plain;charset=utf-8</value>
                    <value>application/json;charset=utf-8</value>
                    <value>application/x-www-form-urlencoded</value>
                </list>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>
配置视图映射
<bean id="viewResolver"  class="org.springframework.web.servlet.view.InternalResourceViewResolver">
       <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
       <property name="prefix" value="/WEB-INF/resoures/" />
       <property name="suffix" value=".jsp"></property>
 </bean>
