二维数组转化为json

例： 二维数组格式 1,手机进水,123,321,1,手机进水,123,321/**      *js数组转json      *      */      function arrayToJson(o) {       var r = [];       if (typeof o == "string") return "\"" + o.replace(/([\'\"\\])/g, "\\$1").replace(/(\n)/g, "\\n").replace(/(\r)/g, "\\r").replace(/(\t)/g, "\\t") + "\"";       if (typeof o == "object") {       if (!o.sort) {       for (var i in o)       r.push(i + ":" + arrayToJson(o[i]));       if (!!document.all && !/^\n?function\s*toString\(\)\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test(o.toString)) {       r.push("toString:" + o.toString.toString());       }       r = "{" + r.join() + "}";       } else {       for (var i = 0; i < o.length; i++) {       r.push(arrayToJson(o[i]));       }       r = "[" + r.join() + "]";       }       return r;       }       return o.toString();       }  调这个JS方法转化后   为  [["1","手机进水","123","321"],["1","手机进水","123","321"]]然后在Java里转化为具体的对象 ，封装成你需要的格式就行了JSON需要下载一个jar包：下载地址：http://code.alibabatech.com/svn/fastjson/repository/com/alibaba/fastjson/1.0.4/fastjson-1.0.4.jarpublic List JsonToList(String arr){List relReceiveFaultList = new ArrayList<RelChecklistFault>();com.alibaba.fastjson.JSONArray mainArray=JSON.parseArray(arr);   for(int i=0;i< mainArray.size();i++){   log.info("数组大小:"+mainArray.size());            com.alibaba.fastjson.JSONArray paramObject=(com.alibaba.fastjson.JSONArray)mainArray.get(i);             RelChecklistFault  relChecklistFault= new RelChecklistFault();           relChecklistFault.setFaultType(paramObject.get(0).toString());           relChecklistFault.setFaultSymptom(paramObject.get(1).toString());           relChecklistFault.setFaultCause(paramObject.get(2).toString());           relChecklistFault.setSuggest(paramObject.get(3).toString());  relReceiveFaultList.add(relChecklistFault);       }  return relReceiveFaultList;}
