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：

	public 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;

	}
