json字符串
{
"code": 200,
"msg": "成功",
"data": {
"recordList": [
{
"name": "lili",
"age": 18
},
{
"name": "quincy",
"age": 20
}
]
}
}
将json字符串转化JSON对象
JSONObject json = JSONObject.parseObject(jsonStr);
获取JSON对象中的list数组
JSONObject data = (JSONObject) json.get("data");
JSONArray list = data.getJSONArray("recordList");
新建JSON对象,赋值，将JSON对象转化为json字符串
JSONObject result = new JSONObject();
result.put("total", list.size());
result.put("rows", list);
String jsonStr = result.toJSONString();
将json字符串转化为javabean
TestPerson person = JSON.parseObject(jsonstr, TestPerson.class);
personListStr = "[{"name":"aa","age":"22"},{"name":"2","bb":"30"}]";
List<TestPerson> personList = JSONObject.parseArray(personListStr, TestPerson.class);
