fastjson妙用

fastjson在java开发中有妙用

    public  List<DmTableWithDomainPath>  DmTables2DmTableWithDomainPaths(List<DmTable> tables){
        List<DmTableWithDomainPath> dmTableWithDomainPaths = new ArrayList<>();
        tables.forEach(table->{
            // java对象转换成json对象
            JSONObject tableJSONObject = (JSONObject) JSON.toJSON(table);
            int domainID= table.getDomainId();
            if (domainID!=0){
                DmDomain dmDomain = dmDomainServiceImpl.queryInfoByNatrualKey(domainID);
                if (dmDomain!=null) {
                     // json对象添加键值对
                    tableJSONObject.put("paths", dmDomain.getPaths());
                }
                // json对象转换成json字符串
                String tableStr= JSON.toJSONString(tableJSONObject);
                // json字符串转换成另一个java对象
                DmTableWithDomainPath dmTableWithDomainPath =JSON.parseObject(tableStr,DmTableWithDomainPath.class);

                dmTableWithDomainPaths.add(dmTableWithDomainPath);
            }
        });
        return  dmTableWithDomainPaths;
    }
