mybatis 实现分页功能， mybatis plus 实现分页功能

1 mybatis 实现分页功能

    @ApiModelProperty(value = "开始页")private Integer page = 1;@ApiModelProperty(value = "每页数据个数")private Integer rows = 10;

以上是前端传过来的数据

    @Overridepublic Map<String,Object> getFbList(EleInput EleInput) {HashMap<String, Object> stringObjectHashMap = new HashMap<>();Integer page = EleInput.getPage();Integer rows = EleInput.getRows();EleInput.setPage((page - 1)*rows);List<Ele> fbList = EleMapper.getFbList(EleInput);int fbListCount = EleMapper.getFbListCount(EleInput);stringObjectHashMap.put("list",fbList);stringObjectHashMap.put("count",fbListCount);return stringObjectHashMap;}

xml 里面写法

在这里插入图片描述

2 mybatis plus 实现分页功能

@Configuration
//@MapperScan("com.example.demo.mapper")
public class MybatisPlusConfig {/*** 新增分页拦截器，并设置数据库类型为mysql* @return*/@Beanpublic MybatisPlusInterceptor mybatisPlusInterceptor() {MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));return interceptor;}}

业务层

        //分页参数Page<SchoolStudent> rowPage = new Page(page, pageSize);//queryWrapper组装查询where条件LambdaQueryWrapper<SchoolStudent> queryWrapper = new LambdaQueryWrapper<>();rowPage = this.baseMapper.selectPage(rowPage, queryWrapper);return rowPage;
