mybatis ---- 分页查询，，源码

 PageHelper 有封装的分页插件---直接用即可

@GetMapping("/toDeptList")public BaseResponse toDeptList(Model model,@RequestParam(required = false,defaultValue = "1",value = "pn")Integer pn ) {    BaseResponse response = new BaseResponse();    try{        PageHelper.startPage(pn, 15);  //pn--页数，定值---每页的数量        List<ReleaseBase> rbList = rbService.searchData();      //查询表里所有的数据        PageInfo<ReleaseBase>  p = new PageInfo<>(rbList);        model.addAttribute("deptList", rbList);        model.addAttribute("page", p);        response.setData(rbList);        response.setSuccess(true);        return response;    }catch (Exception e){        response.setErrorMsg(ErrorCode.SYSTEM_ERROR.getDesc());    }    return response;}

sql ：//根据需求要求条件查询

@Select(" SELECT  rb.*,cp.scale  FROM release_base rb,company cp WHERE  rb.is_bid LIKE ‘%${is_bid}%‘ AND rb.live LIKE ‘%${live}%‘ AND rb.education LIKE ‘%${education}%‘ AND rb.bounty LIKE ‘%${bounty}%‘ AND rb.num LIKE ‘%${num}%‘ AND rb.type like ‘%${type}%‘ AND rb.creat_time LIKE ‘%${creat_time}%‘ AND cp.scale LIKE ‘%${scale}%‘ and rb.category_name LIKE ‘%${category_name}%‘ group  by  creat_time  ")List<ReleaseBase> searchData();
