后端解析省市县前端JSON net.sf.json.JSONObject maven依赖

前言

解析一个json前端字符串，写个工具类

pom

需要一个json jar包

        
		<dependency>
			<groupId>net.sf.json-libgroupId>
			<artifactId>json-libartifactId>
			<version>2.4version>
			<classifier>jdk15classifier>
		dependency>
	
		<dependency>
			<groupId>com.alibabagroupId>
			<artifactId>fastjsonartifactId>
			<version>1.2.39version>
		dependency>

封装

import com.alibaba.fastjson.JSON;
import net.sf.json.JSONObject;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

/**

public class utils {
 
    public static List<City> convertJson(String json){
        JSONObject jsonObject = JSONObject.fromObject(json);
        Map<String, Object> map = (Map)jsonObject;
        List<City>  cityList=new ArrayList<>();
        for (String cityname : map.keySet()) {
            Object  zijson = map.get(cityname);
            City city = JSON.parseObject(zijson+"",City.class);
            city.setName(cityname);
            String items = city.getItems();
            JSONObject areajson = JSONObject.fromObject(items);
            Map<String,Object> map2 = (Map)areajson;
            List<Area> areasList=new ArrayList<>();
            for (String quName : map2.keySet()) {
                Area area = new Area();
                area.setName(quName);
                Object quCode = map2.get(quName);
                area.setCode(Integer.parseInt(quCode+""));
                areasList.add(area);
            }
            city.setAreas(areasList);
            cityList.add(city);
        }

        return cityList;
    }
}

相当于一个工具类

 public class City {
    private String name;
    private int val;
    private String  items;
    private List<Area> areas;
 }
 public class Area {
    private String name;
    private int code;
}
