[Java教程]数组json格式的字符串 转 listBean


1.  字符串形式:

[  {    "userid": "admin",    "name": "admin",    "password": "MTIzNDU2",    "flag": 1,    "createtime": 1467277229000,    "nickname": "",    "thumbnail": null,    "lastDate": null,    "status": null,    "region": "22222"  },  {    "userid": "administrator",    "name": "administrator",    "password": "MTIzNDU2",    "flag": 0,    "createtime": 1467252566000,    "nickname": "超级管理员用户",    "thumbnail": null,    "lastDate": null,    "status": null,    "region": ""  }]

2. javabean

import java.util.Date;public class User {  private String userid;  private String name;  private String password;  private Byte flag;  private Date createtime;  private String nickname;  private String thumbnail;  private Date lastDate;  private Byte status;  private String region;  public String getUserid() {    return userid;  }  public void setUserid(String userid) {    this.userid = userid == null ? null : userid.trim();  }  public String getName() {    return name;  }  public void setName(String name) {    this.name = name == null ? null : name.trim();  }  public String getPassword() {    return password;  }  public void setPassword(String password) {    this.password = password == null ? null : password.trim();  }  public Byte getFlag() {    return flag;  }  public void setFlag(Byte flag) {    this.flag = flag;  }  public Date getCreatetime() {    return createtime;  }  public void setCreatetime(Date createtime) {    this.createtime = createtime;  }  public String getNickname() {    return nickname;  }  public void setNickname(String nickname) {    this.nickname = nickname == null ? null : nickname.trim();  }  public String getThumbnail() {    return thumbnail;  }  public void setThumbnail(String thumbnail) {    this.thumbnail = thumbnail == null ? null : thumbnail.trim();  }  public Date getLastDate() {    return lastDate;  }  public void setLastDate(Date lastDate) {    this.lastDate = lastDate;  }  public Byte getStatus() {    return status;  }  public void setStatus(Byte status) {    this.status = status;  }  public String getRegion() {    return region;  }  public void setRegion(String region) {    this.region = region == null ? null : region.trim();  }}

 

3. 转化

     String listUsers = userClient.listUsers();    JSONArray jArray= JSONArray.fromObject(listUsers);    Collection collection = JSONArray.toCollection(jArray, User.class);    List<User> userList = new ArrayList<User>();    Iterator it = collection.iterator();    while (it.hasNext()) {      User user = (User) it.next();      userList.add(user);    }
