使用fastjson实现Map和Java Bean互转

Map转Java Bean：

public ResponseResult addDataTable(Map<String, Object> params) {
        String jsonString = JSON.toJSONString(params);
        DmDataTable dataTable = JSON.parseObject(jsonString, DmDataTable.class);
        DmApprovalInfo approvalInfo = JSON.parseObject(jsonString, DmApprovalInfo.class);
        return new ResponseResult(insertSelective(dataTable.setTableId(UUIDUtil.uuid())));
    }

Java Bean转Map：

OrganStaffDto staffDto = queryStaffDtoByOrganId(user2.get("organId"));
String jsonStr = JSON.toJSONString(staffDto);
Map<String,String> staffMap = (Map)JSON.parseObject(jsonStr);
