Mybatis之PageHelper分页插件

使用该插件，快速实现查询结果的分页，使用步骤如下

1、pom.xml中导入依赖

        <dependency>
            <groupId>com.github.pagehelpergroupId>
            <artifactId>pagehelperartifactId>
            <version>5.1.6version>
        dependency>

2、mybatis全局配置文件中配置标签

<configuration>

    <properties resource="db.properties"/>

    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
            <property name="helperDialect" value="mysql"/>
        plugin>
    plugins>
    
    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC">
                <property name="..." value="..."/>
            transactionManager>
            <dataSource type="POOLED">
                <property name="driver" value="${driver}"/>
                <property name="url" value="${url}"/>
                <property name="username" value="${username}"/>
                <property name="password" value="${password}"/>
            dataSource>
        environment>
    environments>

    <mappers>
        <mapper resource="chen/mapper/StudentMapper.xml"/>
    mappers>
configuration>

3、在查询前，先设置分页信息

//查询第一页，每页三条数据
PageHelper.startPage(1,3);

4、结果
