第一种方法:
String str = "{\'array\':[{\'id\':5,\'name\':\'张三\'},{\'id\':6,\'name\':\'李四\'}]}";
JSONArray jsonArray = null;
jsonArray = jsonobj.getJSONArray("array");//获取数组
System.out.println(jsonArray.getJSONObject(0).get("name"));
String str = "[{\'columnId\':5,\'columnName\':\'人文历史\'},{\'columnId\':2,\'columnName\':\'商业视野\'}]}";
JSONArray jsonArray = null;
jsonArray = new JSONArray(str);
System.out.println(jsonArray.getJSONObject(0).get("columnName"));
第二种方法:
JSONObject json1=JSONObject.fromObject("{\'username\' : \'11111\',\'clientid\' : \'\',\'password\' : \'222222\'}");
Map<String, Object> map =json1;
for (Entry<String, Object> entry : map.entrySet()) {
System.out.println(entry.getKey()+"="+entry.getValue());
}
