mybatis-plus物理分頁插件使用

mp框架提供了物理分頁插件，我們下面來看下如何實現：

 

首先配置一個PaginationInterceptor的bean；

package com.java1234.config;
  
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
  
/**
 * MybatisPlus配置類
 * @author java1234_小鋒
 * @site www.java1234.com
 * @company Java知識分享網
 * @create 2020-09-07 14:03
 */
@Configuration
public class MybatisPlusConfig {
  
    /**
     * mybatis-plus分頁插件
     * @return
     */
    @Bean
    public PaginationInterceptor paginationInterceptor(){
        return new PaginationInterceptor();
    }
  
}

帶分頁查詢：

/**
 * 查找薪水大於3200  帶分頁
 * sql： select * from t_employee where salary>3200
 */
@Test
public void selectByQueryWrapperWithPage(){
    QueryWrapper<Employee> queryWrapper=new QueryWrapper();
    queryWrapper.gt("salary",3200);
  
    Page<Employee> page = new Page<>(1, 3);
  
    Page<Employee> employeePage = employeeMapper.selectPage(page, queryWrapper);
    System.out.println("總記錄數："+employeePage.getTotal());
    System.out.println("總頁數："+employeePage.getPages());
    System.out.println("當前頁數據："+employeePage.getRecords());
     
}
