mybatis返回结果映射成List<MapString,Object>>  
xml:

mapper：

List<Map<String, Object>> getProjectRate();

service：

@Override
        public List<Map<String, Object>> getProjectRate(){
    
            return monthlyReportMapper.getProjectRate();
        }

controller:

@RequestMapping(value = "/getProjectRate", method = {RequestMethod.GET})
        public JsonResult getProjectRate(){
            List<Map<String, Object>> list = monthlyReportService.getProjectRate();
            return new JsonResult(StatusCode.OK, list);
        }

返回结果：
