查询过滤器用法

• 查询过滤器用法

QueryWrapper<?> queryWrapper = QueryGenerator.initQueryWrapper(?, req.getParameterMap());

代码示例：

    @GetMapping(value = "/list")
    public Result<IPage<JeecgDemo>> list(JeecgDemo jeecgDemo, @RequestParam(name = "pageNo", defaultValue = "1") Integer pageNo, 
                                         @RequestParam(name = "pageSize", defaultValue = "10") Integer pageSize,
            HttpServletRequest req) {
        Result<IPage<JeecgDemo>> result = new Result<IPage<JeecgDemo>>();
        //调用QueryGenerator的initQueryWrapper
        QueryWrapper<JeecgDemo> queryWrapper = QueryGenerator.initQueryWrapper(jeecgDemo, req.getParameterMap());
        Page<JeecgDemo> page = new Page<JeecgDemo>(pageNo, pageSize);
        IPage<JeecgDemo> pageList = jeecgDemoService.page(page, queryWrapper);
        result.setSuccess(true);
        result.setResult(pageList);
        return result;
    }
