The most authoritative json custom format

1. Packaging result, the returned object as

public class the Result <T> {
    
    Private int code;
    Private String MSG;
    Private Data T;
    
    / **
     * successful call time
     * * /
    public static <T> the Result <T> Success ( Data T) {
        return new new the Result <T> (Data);
    }
    
    / **
     * when the call failed
     * * /
    public static <T> the Result <T> error (codeMsg codeMsg) {
        return new new the Result <T> (codeMsg) ;
    }
    

/ **
     * successful constructor
     * @param Data
     * /
    Private the Result (T Data) {
        this.code = 000000; 000000 // default is successful
        this.msg = "sUCCESS";
        this.data = Data;
    }
    
    the Result Private (int code, String MSG) {
        this.code = code;
        this.msg MSG =;
    }
    / **
     * constructor fail
     * @param code
     * @param MSG
     * /
    Private the Result (CodeMsg codeMsg) {
        IF ( ! codeMsg = null) {
            this.code codeMsg.getCode = ();
            this.msg codeMsg.getMsg = ();
        }
    }
 GET (), SET ();
}

2. package CodeMsg, there is stored the code corresponding to the definition of MSG

public class CodeMsg {
    
    Private int code;
    Private String MSG;
    
    // generic error code
    public static CodeMsg SUCCESS = new CodeMsg ( 0, "success");
    public static CodeMsg SERVER_ERROR = new CodeMsg ( 500100, " Exception server");
    public static CodeMsg BIND_ERROR new new CodeMsg = (500 101, "verification error parameters:% S");
    // login module 5002XX
    public static CodeMsg SESSION_ERROR = new new CodeMsg (500210, "Session does not exist or has failed");
    public static CodeMsg PASSWORD_EMPTY = new new CodeMsg (500 211, "password can not be empty");
    public static CodeMsg MOBILE_EMPTY = new new CodeMsg (500 212, "the phone number can not be empty") ;
    public static CodeMsg MOBILE_ERROR = new new CodeMsg (500 213, "phone number format error");
    public static CodeMsg MOBILE_NOT_EXIST = new new CodeMsg (500 214, "the phone number does not exist");
    public static CodeMsg PASSWORD_ERROR = new new CodeMsg (500 215, "the password is wrong ");
    
    // commodity module 5003XX
    
    // Orders module 5004XX
    
    // spike module 5005XX
    
    Private CodeMsg () {
    }
            
    private CodeMsg( int code,String msg ) {
        this.code = code;
        this.msg = msg;
    }
   
    //不定参的构造函数
    public  fillArgs(Object... args) {
        int code = this.code;
        String message = String.format(this.msg, args);
        return new CodeMsg(code, message);
    }

    @Override
    public String toString() {
        return "CodeMsg [code=" + code + ", msg=" + msg + "]";
    }
    get(),set()方法
    
}
3.应用实例

 return Result.success(user);

return Result.error(CodeMsg.MOBILE_ERROR);
