JSONArray数据转换为实体类
标签：collect 对象 ble input EDA 包括 cep 取出 on()
TableA、TableB 是根据json数据创建的实体类 建议将json数据放到json.cn
里面格式化
json-lib是一个java类库，提供将Java对象，包括beans, maps, collections, java arrays and XML等转换成JSON，或者反向转换的功能。
import net.sf.json.*;
import java.io.*;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
import java.util.ArrayList;
import java.util.List;
public class findElectSet {
/*
* 取出文件内容，填充对象
*/
public List writeFile(String path) {
List tableAS = new ArrayList();
String sets = ReadFile(path);//获得json文件的内容
JSONObject jsonObject = JSONObject.fromObject(sets);//格式化成json对象
Object data = jsonObject.get("data");
JSONObject jsonObject1 = JSONObject.fromObject(data);
String list = jsonObject1.getString("list");
JSONArray jsonArray = JSONArray.fromObject(list);
List tableAList = new ArrayList();
for (Object o : jsonArray) {
JSONObject jo = JSONObject.fromObject(o);
TableA tableA = new TableA();
tableA.setId(jo.getString("id"));
tableA.setZbbmText(jo.getString("zbbmText"));
tableA.setCreateDate(jo.getString("createDate"));
tableA.setTopic(jo.getString("topic"));
tableA.setCreateUserText(jo.getString("createUserText"));
tableA.setWh(jo.getString("wh"));
tableA.setFwrq(jo.getString("fwrq"));
List tableBList = new ArrayList();
String attlist = jo.getString("attlist");
JSONArray jsonArray1 = JSONArray.fromObject(attlist);
for (Object jsonArr1 : jsonArray1) {
JSONObject j = JSONObject.fromObject(jsonArr1);
TableB tableB = new TableB();
tableB.setContentId(j.getString("contentId"));
tableB.setDurl(j.getString("durl"));
tableB.setTopic(j.getString("topic"));
tableB.setType(j.getString("type"));
tableBList.add(tableB);
}
tableA.setAttlist(tableBList);
tableAList.add(tableA);
}
return tableAList;
}
//读文件，返回字符串
public String ReadFile(String path) {
StringBuffer strBuf = new StringBuffer();
try {
URL url = new URL(path);
URLConnection conn = url.openConnection();
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
String line = null;
while((line = reader.readLine()) != null) {
strBuf.append(line + " ");
}
reader.close();
} catch (MalformedURLException e) {
System.out.println();
} catch (IOException e) {
System.out.println(e);
}
return strBuf.toString();
}
}
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
findElectSet f=new findElectSet();
List tableAS = f.writeFile("http://XXXXXXXXXXXXXXXXX");
System.out.println(tableAS.toString());
}
