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

    <!--配置Mybatis的SQL会话工厂-->

    <property name="dataSource" ref="dataSource"/>
    <!--        指定映射配置文件路径-->
    <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    <!--        指定类型别名包-->
    <property name="typeAliasesPackage" value="cn.wh.entity"/>
    <property name="configuration">

    <!--                开启下划线转驼峰命名-->
        <property name="mapUnderscoreToCamelCase" value="true"/>
    </bean>
    </property>
        <property name="plugins">
            <array>
                <!--                指定分页插件-->
                <bean class="com.github.pagehelper.PageInterceptor">
                    <property name="properties">
                        <props>
                            <!--                            指定SQL方言-->
                            <prop key="helperDialect">mysql</prop>

    </bean>
    <!--配置映射扫描配置对象-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.example.dao"/>
        <property name="sqlSessionFactoryBeanName" value="factoryBean"/>
    </bean>
</beans>

2，web.xml配置

<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:webconfig.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
