{
    "Code": 200,
    "Message": "登錄成功似炎！",
    "Data": {
            "IDCardNum": "32098122226112495",
            "MemberMobile": "123123444",

}

如何進(jìn)行解析呢辛萍？Data 里面放的是一個(gè)用戶對(duì)象。那么首先我們要?jiǎng)?chuàng)建一個(gè)用戶類(lèi)羡藐。

public class UserEntity implements Serializable {

    /**
     * IDCardNum : 32098122226112495
     * MemberMobile : 123123444
     * MemberName : 楊x
     * Balance : 460
     * IsEnabled : 1
     * CreatedDate : 2016-12-09 19:43:22.187
     * LastLoginTime : 2016-12-09 19:43:22.187
     * LastLoginIP : 192.168.199.153
     */

      @SerializedName("IDCardNum")//可使用該注解 重命名
    private String cardNum;
    private String MemberMobile;
    private String MemberName;
    private int Balance;
    private int IsEnabled;
    private String CreatedDate;
    private String LastLoginTime;
    private String LastLoginIP;

  //各種set get

如何解析呢贩毕？

String json ="";//就是服務(wù)器返回的數(shù)據(jù)
  ResultDataEntity<UserEntity> userResult =ResultDataEntity.fromJson(json ,UserEntity.class);

UserEntity userEntity =userResult .getData();//取得用戶對(duì)象，然后進(jìn)行各種操作
