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<proDetail.length;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:‘<%=basePath%>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
<!-- https://mvnrepository.com/artifact/org.json/json --> <dependency> <groupId>org.json</groupId> <artifactId>json</artifactId> <version>20170516</version> </dependency>
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<OutStoDetail> outSDList=new ArrayList<OutStoDetail>(); JSONArray js = new JSONArray(jsonStr); for (int i = 0; i < js.length(); 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。
