json数据的拼接与解析

json数据格式
[{ "firstName": "Brett", "lastName":"McLaughlin", "email": "aaaa" },
{ "firstName": "Jason", "lastName":"Hunter", "email": "bbbb"},
{ "firstName": "Elliotte", "lastName":"Harold", "email": "cccc" }]
一、前台js代码（数据存储与json拼接）
以OutStoDetail类为例
var proDetail=[];//大的集合
obj.outstodeid=outstodeid; //对象属性
obj.proname=proname;
obj.proprice=proprice;
obj.procount=procount;
obj.proamount=proamount;
obj.storagenum=storagenum;
obj.localnum=localnum;
proDetail.push(obj ); //对象放入集合
$("#btnSave").click(function(){
var jsonStr="[";
for(i=0;i){
jsonStr+="{";
jsonStr+="\"outstodeid\":\""+proDetail[i].outstodeid+"\",";
jsonStr+="\"proname\":\""+proDetail[i].proname+"\",";
jsonStr+="\"proprice\":\""+proDetail[i].proprice+"\",";
jsonStr+="\"procount\":\""+proDetail[i].procount+"\",";
jsonStr+="\"proamount\":\""+proDetail[i].proamount+"\",";
jsonStr+="\"storagenum\":\""+proDetail[i].storagenum+"\",";
jsonStr+="\"localnum\":\""+proDetail[i].localnum+"\"";
jsonStr+="}";
if(i!=proDetail.length-1) jsonStr+=",";
}
jsonStr+="]";
$.ajax({
type:"post",
url:‘outStore/updateOrAdd.action?jsonStr=‘+jsonStr,
success:function(data,status){}
});
});
拼接json串时注意引号的拼接。
二、后台java代码（json数据解析）
1、在maven项目pom.xml中添加如下依赖
或下载org.json的jar包
2、在controller中对json数据进行解析
引入包
import org.json.JSONArray;
import org.json.JSONObject;
List outSDList=new ArrayList();
JSONArray js = new JSONArray(jsonStr);
for (int i = 0; i ) {
JSONObject ob = js.getJSONObject(i);
OutStoDetail outStoDetail=new OutStoDetail();
//outStoDetail.setOutstodeid(Integer.parseInt((String) ob.get("outstodeid")));
outStoDetail.setProname((String)ob.get("proname"));
outStoDetail.setProprice(Float.parseFloat((String)ob.get("proprice")));
outStoDetail.setProcount(Float.parseFloat((String)ob.get("procount")));
outStoDetail.setProamount(Float.parseFloat((String)ob.get("proamount")));
outStoDetail.setStoragenum((String)ob.get("storagenum"));
outStoDetail.setLocalnum((String)ob.get("localnum"));
outStoDetail.setOutstonum(outStor.getOutstonum());
outSDList.add(outStoDetail);
}
获取到OutStoDetail类型的集合就可以使用了。
