1、pom引入jar

<dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper</artifactId>
            <version>4.1.6</version>
        </dependency>

2、jdbc中配置

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean
 
">
         <property name="configLocation" value="classpath:spring/mybatis-config.xml"/>
        <property name="dataSource" ref="dataSource" />
        <property name="typeAliasesPackage" value="com.ybd.demo.model" />
        <property name="mapperLocations" value="classpath*:com/xx/demo/mapper/*.xml
 
" />
        <property name="plugins">
            <array>
                <bean class="com.github.pagehelper.PageHelper">
                    <property name="properties">
                        <value>
                            dialect=mysql
                        
 
</value>
                    </property>
                </bean>
            </array>
        </property>
    </bean>
