シングルポイント登録3

ログイン時には、クライアントだけでなくサーバー側も完全な登録項目です.
前の二つの編を通して分かるように、私のアーキテクチャはspringのMVCとspring注釈を使っていますが、実は全然分かりません.
以下はログイン方法のコードで、ローカルログインとクライアントのログインの2種類があります.

		setResponse(response, resultCode, result);
	}
	
	
	//    ，            。
	@RequestMapping(value = "/tuloginMethod")
	public void login(@RequestBody Map<String, Object> map,

		setResponseMethod(response, resultCode, result, user , token);
	}
	
	
	//tokenMethod，  token,           。

	public void tuloginMethod(@RequestBody Map<String, Object> map,

		String ret = "";
        try {
			PrintWriter out = response.getWriter();
			if(tokenServer){
				ret = "success";
				out.println(ret);
	            out.close();
			}else{
				ret = "noLogin";
				out.println(ret);
	            out.close();
			}
			
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

その中で、方法の後の

setResponseMethod

この方法は、値を伝えるもので、jsonを通じて値を伝えます.フロントにあげるか、クライアントにあげるか.
以下はコードです

protected void setResponse(HttpServletResponse resp, ResultCode resultCode,
            Object result) {
        setResponse(resp, resultCode, result, null);
    }

    protected void setResponse(HttpServletResponse resp, ResultCode resultCode,
            Object result, String callback) {
        try {
            resp.setCharacterEncoding("utf-8");
            PrintWriter out = resp.getWriter();

            Map<String, Object> ret = new LinkedHashMap<String, Object>();
            ret.put("code", resultCode.getCode());
            ret.put("data", result);
            String responseStr = GSON.toJson(ret);
            out.println(responseStr);
            out.close();

        } catch (Exception e) {
            logger.error(e.getMessage(), e);
        }
    }

これは前のページの転送値です.
もう一つは、クライアントに値を渡すことです.コードは以下の通りです.

protected void setResponseMethod(HttpServletResponse resp, ResultCode resultCode,
            Object result,User user,String token) {
        setResponseMethod(resp, resultCode, result,user,token , null);
    }
    protected void setResponseMethod(HttpServletResponse resp, ResultCode resultCode,
            Object result,User user ,String token , String callback) {
        try {
        	resp.setCharacterEncoding("utf-8");
            PrintWriter out = resp.getWriter();
            Map<String, Object> ret = new LinkedHashMap<String, Object>();
            ret.put("code", resultCode.getCode());
            ret.put("data", result);
            ret.put("user", user);
            ret.put("token", token);
            String responseStr = GSON.toJson(ret);
            out.println(responseStr);
            out.close();
            resp.setCharacterEncoding("utf-8");
            
            
        } catch (Exception e) {
            logger.error(e.getMessage(), e);
        }
    }

この二つのリレーのjsonは、二つの問題を引き起こしました.
一つは、JSでJSONをどのように解析し、その中のデータを取得するかです.
一つは、Jsonの中のJsonがどのようにUserの対象に転化しますか?
この二つの問題は他の二つの文章を見ましょう.
