一、java普通对象和json字符串的互转java对象---->json首先创建一个java对象： public class Student {
//姓名
private String name;
//年龄
private String age;
//住址
private String address;
public String g
net.sf.json.JSONObject cannot be cast to java.util.Map。故而只能通过查询JSONObject对象的方法，写成用Iterator迭代的方法遍历key。注：可能由于使用的类不同：我的环境：smartbi.net.sf.json.JSONObject; 网上是使用的：net.sf.json.JSONObject。package shenji.suzh
public class User {
private Integer userId;
private String username;
private int sex;
private Integer age;
public Integer getUserId() {
return userId;
}
public void setUserId(Integer use
方法： public class ListToMapTest { public Map listToMap(List<User> list) { Map<Integer, User> map = new HashMap<>(); for (User user : list) { map = list ...
一、JSON格式{"code":"200","msg":"success","data":["Yinqing","ArtCreativity"]}二、json格式转为List集合代码@Test
public void test()
{
String post = "{\"code\":\"200\",\"msg\":\"success\",\"data\":[\"Y
