2.框架层：
单个基本变量用：@RequestParam(name = “column”, required = false) String sortColumn：
集合对象变量：@RequestBody List companyIds，
单个类对象: @RequestBody @Valid MembersAssessmentConfigDto dto
多个集合对象：@RequestBody Map<String, PsDeptCostDto> map
3.复杂组合传值用：
@RequestBody MembersAssessmentConfigDto dto,
@RequestParam(name = “column”, required = false) String sortColumn,
@RequestParam(name = “order”, defaultValue = “ASC”, required = false) String sortType,
HttpServletRequest req
）

2.SQL warpper封装

private QueryWrapper<EmpInfResLev> generateQueryWrapper(EmpInfResLev empInfResLevEntity, HttpServletRequest req,String sortColumn,boolean isAsc) {
        // 使用QueryWrapper实现单表的组合查询条件自动拼接，String类型默认为模糊查询
        String workingLevel =  empInfResLevEntity.getWorkingLevel();
        empInfResLevEntity.setWorkingLevel(null);
        QueryWrapper<EmpInfResLev> queryWrapper = QueryGenerator.initQueryWrapper(empInfResLevEntity, req.getParameterMap()).orderBy(true,isAsc,sortColumn);
        if(StringUtils.isNotEmpty(workingLevel)){
            queryWrapper.eq("working_level",workingLevel);
        }
        queryWrapper.eq(!StringUtils.isEmpty(empInfResLevEntity.getPostLevel()),"post_level", empInfResLevEntity.getPostLevel());

        // log.info("------------配装列表查询的条件------------------");
        // 自定义高级查询
        Map paramMap = req.getParameterMap();
        return queryWrapper;
    }
