方式一：使用原生的PageHelper

1.在pom.xml中引入依賴

   <dependency>
           <groupId>com.github.pagehelper</groupId>
           <artifactId>pagehelper-spring-boot-starter</artifactId>
           <version>1.2.10</version>
       </dependency>

2.在springboot的啟動(dòng)類(lèi)（Application.java)里面注入配置

@Bean

    PageHelper pageHelper(){

        //分頁(yè)插件

        PageHelper pageHelper = new PageHelper();

        Properties properties = new Properties();

        properties.setProperty("reasonable", "true");

        properties.setProperty("supportMethodsArguments", "true");

        properties.setProperty("returnPageInfo", "check");

        properties.setProperty("params", "count=countSql");

        pageHelper.setProperties(properties);

        //添加插件

        new SqlSessionFactoryBean().setPlugins(new Interceptor[]{pageHelper});

        return pageHelper;

    }

方式二：使用PageHelper的starter

1.在pom.xml中引入依賴

    <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.2.10</version>
        </dependency>

2.在application.properties配置pagehelper的屬性

#pagehelper分頁(yè)插件配置

pagehelper.helperDialect=mysql

pagehelper.reasonable=true

pagehelper.supportMethodsArguments=true

pagehelper.params=count=countSql

使用方法：

1.在查詢語(yǔ)句之前插入下列語(yǔ)句：

PageHelper.startPage(pageNum, pageSize);

2.屬性介紹：

System.out.println("當(dāng)前頁(yè)："+pageInfo.getPageNun());

System.out.println("每頁(yè)顯示記錄數(shù)："+pageInfo.getPageSize());

System.out.println("總頁(yè)數(shù)："+pageInfo.getPages());

System.out.println("總記錄數(shù)："+pageInfo.getTotal());

System.out.println("是否有上一頁(yè)："+pageInfo.isHasPreviousPage());

System.out.println("是否有下一頁(yè)："+pageInfo.isHasNextPage());

System.out.println("導(dǎo)航頁(yè)面："+Arrays.toString(pageInfo.getNavigatepageNums()));

例如：

1.在service層寫(xiě)入

public PageInfo<VisitorRecord> getVisitorRecordByCondition(Map<String, Object> condition, int pageNum,Integer pageSize) {

        PageHelper.startPage(pageNum, pageSize);

        List<VisitorRecord> visitorRecord = visitorRecordDao.getVisitorRecordByCondition(condition);

        PageInfo<VisitorRecord> pageInfo = new PageInfo<>(visitorRecord);

        return pageInfo;

}

2.控制器層

PageInfo<VisitorRecord> visitorRecord = visitorRecordService.getVisitorRecordByCondition(condition, pageNumber / pageSize + 1, pageSize);

System.out.println("總記錄數(shù)："+visitorRecord.getTotal());
