Java数据封装类

项目中用到，比较好用！！
用户前端与后台的交互数据，这个封装类中包含分页、数据、错误码、状态码等信息！！
亲测好用哦！

一个类DataWrapper

public class DataWrapper<T>{    private CallStatusEnum callStatus;    private ErrorCodeEnum errorCode;    private T data;    private int numberPerPage; // 用于分页结果    private int currentPage;    private int totalNumber;    private int totalPage;    private String message ;    private String recordUpdateTime ; //redis数据插入时间    public DataWrapper() {        callStatus = CallStatusEnum.SUCCEED;        errorCode = ErrorCodeEnum.No_Error;    }    public static <T> DataWrapper<T> createInstance(){        return new DataWrapper<T>() ;    }    public CallStatusEnum getCallStatus() {        return callStatus;    }    public DataWrapper<T> setCallStatus(CallStatusEnum callStatus) {        this.callStatus = callStatus;        return this ;     }    public ErrorCodeEnum getErrorCode() {        return errorCode;    }    public void setErrorCode(ErrorCodeEnum errorCode) {        this.errorCode = errorCode;        if (!errorCode.equals(ErrorCodeEnum.No_Error)) {            this.callStatus = CallStatusEnum.FAILED;        }    }    public T getData() {        return data;    }    public DataWrapper<T> setData(T data) {        this.data = data;        return this ;    }    public int getNumberPerPage() {        return numberPerPage;    }    public void setNumberPerPage(int numberPerPage) {        this.numberPerPage = numberPerPage;    }    public int getCurrentPage() {        return currentPage;    }    public void setCurrentPage(int currentPage) {        this.currentPage = currentPage;    }    public int getTotalNumber() {        return totalNumber;    }    public void setTotalNumber(int totalNumber) {        this.totalNumber = totalNumber;    }    public int getTotalPage() {        return totalPage;    }    public void setTotalPage(int totalPage) {        this.totalPage = totalPage;    }    public String getMessage() {        return message;    }    public DataWrapper<T> setMessage(String message) {        this.message = message;        return this ;    }    public String getRecordUpdateTime() {        return recordUpdateTime;    }    public DataWrapper<T>  setRecordUpdateTime(String recordUpdateTime) {        this.recordUpdateTime = recordUpdateTime;        return this ;    }    @Override    public String toString() {        return  JSONObject.toJSONString(this) ;    }}

两个枚举CallStatusEnum、ErrorCodeEnum

public enum CallStatusEnum implements Serializable {    SUCCEED,    FAILED,;    CallStatusEnum() {    }}

public enum ErrorCodeEnum implements Serializable {    No_Error("No ERROE!", 0),    Error("Unknown error!", 1),    NO_SUCH_USER("Can't find username",2),    IncorrectCredentials("IncorrectCredentialsException",3),    LoginFailed("AuthenticationException",4),    USER_EXIST("User already exist in db",5),    PASSWORD_ERROR("Error is password",6),    REGISTER_FAILED("Register failed",7),    PARSE_DATE("Parse  Date error",8),    ExcessiveAttempts("Try password more than 5 times",9) ,    NO_ROLE("User has no role!" , 10) ,    USER_STATE_ERROR("User state error! Disable Login" , 11),    USER_IDENTITY_ERROR("User Identity error! Disable Login" , 12),    DB_ERROR("database maybe error!" , 13) ,    WEB_SP_ERROR("from webSp maybe error!" , 14) ,    MFA_VERIFY_ERROR("mfa verify random code error!" , 15) ,    MFA_SEND_ERROR("mfa send random code error!" , 16) ,    MFA_SEND_EXCESSIVE("ask send random code excessive!" , 17),    PHONE_NUMBER_ERROR("phone number is empty or error!" , 18),    IMAGECODE_ERROR("image code error" , 19),    VERIFYCODE_ERROR("telephone verify code incorrect",20);    private String label;    private Integer code;    ErrorCodeEnum() {    }    ErrorCodeEnum(String label, Integer code) {        this.label = label;        this.code = code;    }    public String getLabel() {        return label;    }    public void setLabel(String label) {        this.label = label;    }    public int getCode() {        return code;    }    @Override    public String toString() {        return code.toString();    }    public static ErrorCodeEnum parse(int code) {        for (ErrorCodeEnum theEnum : ErrorCodeEnum.values()) {            if (theEnum.getCode() == code) {                return theEnum;            }        }        return No_Error;    }}
