java后台解析json

lwzlwzgood

var params = {
        data : data.toJson(true) // 将数据集中已变更数据导出为JSON数据
    };
    debugger;
    // 请求成功后的回调方法
   var success = function(resultData) {
        // 保存成功后，必须调用data.applyUpdates()，用于数据集确认数据已更新
       data.applyUpdates();
    };
    // 发送请求
        Baas.sendRequest({
        "url" : "/ct/ct", // servlet请求地址
        "action" : "registersave", // action
        "params" : params, // action对应的参数
        "success" : success  // 请求成功后的回调方法
   });
};

传递到java后台的json数据如下：（有效数据是fName，fPassword，fCreatetime字段）
"@type":"table","rows":[{"fBirthday":{"changed":0},"fCompliments":{"changed":0},"fCreatetime":{"changed":0,"value":"2016-04-13T13:22:55.149Z"},"fName":{"changed":0,"value":"123"},"fPassword":{"changed":0,"value":"123"},"userdata":{"id":{"changed":0,"value":"C7076C0282D00001EDAEE50518A2A170"},"isModified":true,"recordState":"new"}}],"userdata":{"idColumnDefine":"fID","idColumnName":"fID","idColumnType":"String","model":"","relationAlias":"fBirthday,fCompliments,fCreatetime,fName,fPassword","relationTypes":"Date,String,DateTime,String,String,","relations":"fBirthday,fCompliments,fCreatetime,fName,fPassword","tableName":"cowuser","updateMode":"whereVersion"}}

请问在java后台怎么把这三个字段解析出来？只提取这三个字段的值

这个你研究下源码吧！！
source\baas.java.zip  
最终就是转成json对象，然后循环每行数据判断列名和值！
