一：在pom.xml引入相应jar

    <dependency>
      <groupId>com.github.pagehelper</groupId>
      <artifactId>pagehelper</artifactId>
      <version>5.0.1</version>
    </dependency>

 二：有spring的环境的配置

 <!--配置SqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--别名的配置 domain,query-->
        <property name="typeAliasesPackage" value="cn.itsource.ssm.domain,cn.itsource.ssm.query"/>
        <!--mapper的映射文件:配置所有的映射文件-->
        <property name="mapperLocations" value="classpath*:cn/itsource/ssm/mapper/*.xml"/>
        <!--分页插件配置-->
        <property name="plugins">
            <array>
                <bean class="com.github.pagehelper.PageInterceptor">
                    <property name="properties">
                        <value>helperDialect=mysql
                            reasonable=false
                            supportMethodsArguments=true
                            params=count=countSql
                            autoRuntimeDialect=true
                        </value>
                    </property>
                </bean>
            </array>
        </property>

    </bean>

二.一普通maven环境中的配置

<plugin interceptor="com.github.pagehelper.PageInterceptor">

</plugin>
