Mybatis-Plus分頁查詢

dao層

package com.vinsuan.parkingclient.dao;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.vinsuan.parkingclient.domain.vo.PlateNumCarVo;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface PlateNumCarVoMapper extends BaseMapper<PlateNumCarVo> {

    List<PlateNumCarVo> listCarInfo(Page page, @Param("plateNo") String plateNo);

}

　　mapper文件和沒有進行分頁的一樣

service層

package com.vinsuan.parkingclient.service;

import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.baomidou.mybatisplus.extension.service.IService;
import com.vinsuan.parkingclient.domain.vo.PlateNumCarVo;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface PlateNumCarVoService extends IService<PlateNumCarVo> {
    Page<List<PlateNumCarVo>> listPlateNumCar(Page page, @Param("plateNo") String plateNo);

}

　　serviceImpl層：

package com.vinsuan.parkingclient.service.impl;

import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.vinsuan.parkingclient.dao.PlateNumCarVoMapper;
import com.vinsuan.parkingclient.domain.vo.PlateNumCarVo;
import com.vinsuan.parkingclient.service.PlateNumCarVoService;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class PlateNumCarVoServiceImpl extends ServiceImpl<PlateNumCarVoMapper, PlateNumCarVo> implements PlateNumCarVoService {

    @Override
    public Page<List<PlateNumCarVo>> listPlateNumCar(Page page, String plateNo) {
        List<PlateNumCarVo> list = baseMapper.listCarInfo(page, plateNo);
        return page.setRecords(list);
    }
}

　　controlle層：

@ApiOperation(value = "通過車牌名模糊查詢有牌車信息")
    @GetMapping("getCarByPlateNo")
    public R listCarInfo(@RequestParam(value = "pageNum", required = true, defaultValue = "0") Integer pageNum,
                         @RequestParam(value = "pageSize", required = true, defaultValue = "20") Integer pageSize, String plateNo) {
        Page<PlateNumCarVo> page = new Page<>(pageNum, pageSize);
        return new R(plateNumCarVoService.listPlateNumCar(page, plateNo));
    }
