Java Json和Map互转

1.Json转Map

    public static Map JsonToMap(String jsonStr){    
        Map map = new HashMap();    
        JSONObject json = JSONObject.fromObject(jsonStr);    
        for(Object k : json.keySet()){    
            Object v = json.get(k);     
            if(v instanceof JSONArray){    
                List> list = new ArrayList>();    
                Iterator it = ((JSONArray)v).iterator();    
                while(it.hasNext()){    
                    JSONObject json2 = it.next();    
                    list.add(JsonToMap(json2.toString()));    
                }    
                map.put(k.toString(), list);    
            } else {    
                map.put(k.toString(), v);
            }
        }
        return map;
    }

2.Map转Json

        Map param = new HashMap();
        param.put("first",new TemplateData("你好，你有新的挪车通知！","#696969"));
        param.put("keyword1",new TemplateData("测试信息","#696969"));
        param.put("keyword2",new TemplateData("10.07","#696969"));
        param.put("keyword3",new TemplateData("2018-10-10","#696969"));
        param.put("remark",new TemplateData("我在这儿等着你回来 等着你回来把那车挪开","#696969"));
        // net.sf.json.JSONObject 将Map转换为JSON方法
        JSONObject json = JSONObject.fromObject(param);
        System.out.println(json);
         
        // org.json.JSONObject 将Map转换为JSON方法
        /*JSONObject json =new JSONObject(param);*/
