Mybatis-plus使用分頁進行分頁查詢

首先先配置配置文件

@Configuration
public class MybatisPlusConfig {
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }

}

2.進行分頁查詢

   @Test
    public void selectPage() {
        QueryWrapper<User> wrapper = new QueryWrapper<>();
        wrapper.ge("age",26);
        Page<User> page = new Page<>(1, 2);
        IPage<User> userIPage = userMapper.selectPage(page, wrapper);
        System.out.println("總條數"+userIPage.getTotal());
        System.out.println("總頁數"+userIPage.getPages());

    }

   @Test
    public void selectPage() {
        QueryWrapper<User> wrapper = new QueryWrapper<>();
        wrapper.ge("age",26);
        Page<User> page = new Page<>(1, 2);
        IPage<Map<String,Object>> userIPage = userMapper.selectMapsPage(page, wrapper);
        System.out.println("總條數"+userIPage.getTotal());
        System.out.println("總頁數"+userIPage.getPages());
    }
