下面要给大家介绍到的就是和mybatisplus相关的内容，那么它的分页应该怎样做呢?具体的代码实现方式是怎样的?
1、简单单表分页
代码：
public interface StoreService
{
IPage < Store > query(StoreQueryRequest param);
}StoreServiceImpl
@Override
public IPage < Store > query(StoreQueryRequest param)
{
Page < Store > page = new Page < > (param.getPageIndex(), param.getPageSize());
QueryWrapper < Store > qw = new QueryWrapper < > ();
qw.eq("store_id", param.getStoreId);
return storeMapper.selectPage(page, qw);
}StoreController
@GetMapping(value = "/query")
public IPage < Store > query(StoreQueryRequest param)
{
IPage < Store > iPage = storeService.query(param);
return iPage;
}2、多表查询分页
代码：
StoreMapper
public interface StoreMapper extends BaseMapper < Store >
{
List < StoreItemVO > query(IPage < StoreItemVO > page, @Param("param") StoreQueryRequest param);
}StoreMapper.xml <
select id = "query"
parameterType = "com.demo.model.StoreQueryRequest"
resultType = "com.demo.model.StoreItemVO" >
SELECT *
FROM
t_store
<
where >
<if test="param.storeId != null">
and id = #{param.storeId}
</if> <
/where> <
/select>StoreService
public interface StoreService extends IService < Store >
{
IPage < StoreItemVO > query(StoreQueryRequest param);
}StoreServiceImpl
public class StoreServiceImpl extends ServiceImpl < StoreMapper, Store > implements StoreService
{
@Autowired
private StoreMapper StoreMapper;
@Override
public IPage < StoreItemVO > query(StoreQueryRequest param)
{
IPage < StoreItemVO > iPage = new Page < > (param.getPageIndex(), param.getPageSize());
List < StoreItemVO > list = StoreMapper.query(iPage, param);
iPage.setRecords(list);
return iPage;
}
}StoreController
@GetMapping(value = "/query")
public IPage < StoreItemVO query(StoreQueryRequest param)
{
IPage < StoreItemVO > iPage = StoreService.query(param);
return iPage;
}以上ipage和page引用的包
import com.baomidou.mybatisplus.core.metadata.IPage; import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
Store-数据库实体
StoreQueryRequest-请求参数对象
StoreItemVO-自定义对象
