这里博主因为采用的是oracle数据库，所以要导入ojdbc6驱动程序，因为oracle没有授权maven使用ojdbc，所以我们要自己导入ojdbc驱动程序到maven仓库：
1.先在cmd下运行（-Dfile后面的值写你oracle安装目录下的ojdbc包，因为下载oracle会提供ojdbc驱动程序包，所以可以不用在重新下载）
mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.1.0 -Dpackaging=jar -Dfile=F:\app\lenovo\product\11.2.0\dbhome_1\jdbc\lib\ojdbc6.jar
2.然后在pom.xml文件中添加

            <dependency>
                <groupId>com.oraclegroupId>
                <artifactId>ojdbc6artifactId>
                 <version>11.2.0.1.0version>
            dependency>

com.oracle是maven里ojdbc所在的包名，写到这里就够了，不用再写子包。

spring-mvc文件

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    
    <context:component-scan base-package="net.cxp.controller">context:component-scan>

    
    <mvc:annotation-driven enable-matrix-variables="true" />

    
    <bean id="mappingJacksonHttpMessageConverter"
        class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8value>
            list>
        property>
    bean>

    
    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="mappingJacksonHttpMessageConverter" />
            list>
        property>
    bean>

    
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        
        <property name="prefix" value="/" />
        <property name="suffix" value=".jsp" />
    bean>
beans>

这里需要注意的是mappingJacksonHttpMessageConverter。因为spring4.1转json不在使用MappingJacksonHttpMessageConverter，而是使用MappingJackson2HttpMessageConverter，所以使用spring4.1及以上版本的要注意了，改变后的具体写法自行百度吧。

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

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    bean>

beans>

这里博主被这句话折腾了好久

<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />

注意是sqlSessionFactoryBeanName，而不是sqlSessionFactoryBean，后面的是value而不是ref，sqlSessionFactory不是bean吗，应该是ref而不是value才对啊，具体解释参考
mybatis-spring集成：配置多数据库源中遇到的问题–MapperScannerConfigurer配置 ，不这样写的话读jdbc.properties文件时总会报string类型不能转为int型的错误。

最后一点是单元测试的时候，你不能直接run单元测试。
1.首先你要先把mapping文件复制到target\classes…文件夹下，如
F:\Workspaces\springmvc Maven Webapp\target\classes\net\cxp，因为此文件夹下没有映射xml文件。
2.然后右键项目名–>run as–>maven test，之后在进行单元测试。不进行这步的话（F:\Workspaces\springmvc Maven Webapp\target\test-classes），你的test-classes文件夹下没有编译好的测试类class文件，自然会报类没有发现的异常。参考maven中运行junit4报测试类class not found错误——maven test命令
