將json字串轉化成List<Map<String,Object>>物件

Map<String,Object> map = new HashMap<String,Object>();

map.put("key1", "value1");

map.put("key2", "value2");

Map<String,Object> map2 = new HashMap<String,Object>();

map2.put("key1", 1);

map2.put("key2", 2);

List<Map<String,Object>> list = new ArrayList<Map<String,Object>>();

list.add(map);

list.add(map2);

String jsonString = JSON.toJSONString(list);

System.out.println("json字串:"+jsonString);

//解析json字串

List<Map<String,Object>> list2 = JSON.parseObject(jsonString,new TypeReference<List<Map<String,Object>>>(){});
