클래스를 찾지 못하는 오류가 발생했다

jsonException 클래스를 찾지 못하는 거 같았다

 

찾아보니

나는

org.springframework.boot.configurationprocessor 에서 나오는

jsonObject 클래스를 사용 중이었는데

다른 의존성을 사용하는 것으로 바꿔야한다고 한다ㅠㅠ

 

 

그래서

해당 jsonObject 와 jsonException을 사용하는 코드를

 

    public String getTokenSecret(String token, String where, String what) throws JSONException {
        String[] jwt = splitToken(token);
        int x = 0;
        if (where.equals("header")) {
            x = 0;
        }
        if (where.equals("payload")) {
            x = 1;
        }
        if (where.equals("signature")) {
            x = 2;
        }

        //시그니쳐는 byte[] 배열로 받아와야함..
        if (x == 2) {
            byte[] signatureBytes = Base64.getDecoder().decode(jwt[2]);
            return new String(signatureBytes, StandardCharsets.UTF_8);
        }

        byte[] tokenBytes = Base64.getDecoder().decode(jwt[x]);

        String jsonString = new String(tokenBytes, StandardCharsets.UTF_8);
        JSONObject headerJson = new JSONObject(jsonString);

        return String.valueOf(headerJson.get(what));
    }

요걸

 

 

 

얘처럼

public String getTokenSecret(String token, String where, String what) {
String[] jwt = splitToken(token);
int x = 0;
if (where.equals("header")) {
x = 0;
}
if (where.equals("payload")) {
x = 1;
}
if (where.equals("signature")) {
x = 2;
}

//시그니쳐는 byte[] 배열로 받아와야함..
if (x == 2) {
byte[] signatureBytes = Base64.getDecoder().decode(jwt[2]);
return new String(signatureBytes, StandardCharsets.UTF_8);
}

byte[] tokenBytes = Base64.getDecoder().decode(jwt[x]);

String jsonString = new String(tokenBytes, StandardCharsets.UTF_8);
JsonObject headerJson = new JsonObject();
headerJson.addProperty(what, jsonString);

return String.valueOf(headerJson.get(what));
}

 

 

이렇게

com.google.gson.JsonObject 를 사용하도록 변경했다!!!

 

 

 

 

 

잘 빌드되는 것을 확인했다 ㅇ_ㅇ!
