JwtBuilder compact() performance

I use lib JJWT 0.9.0 to generate Token. I have write log code segment generate Token, and I see function compact() run verry slow (664 -151 = 513(ms)) . I used JDK 7. how to the function compact() run faster or How to generate tokens faster? My code:

public String createJWT(String id, String issuer, String subject, List<T> authories, String loginUserData,
            long ttlMillis) {
        //The JWT signature algorithm we will be using to sign the token
        long startTime = System.currentTimeMillis();
        LOGGER.info("createJWT id=" + id + ";issuer=" + ";subject=" + subject);
        SignatureAlgorithm signatureAlgorithm = SignatureAlgorithm.HS512;

        long nowMillis = System.currentTimeMillis();
        Date now = new Date(nowMillis);

        //We will sign our JWT with our ApiKey secret
        byte[] apiKeySecretBytes = DatatypeConverter.parseBase64Binary(ApiSecretKey.getSecretKey());
        Key signingKey = new SecretKeySpec(apiKeySecretBytes, signatureAlgorithm.getJcaName());

        //Let's set the JWT Claims
        JwtBuilder builder = Jwts.builder().setId(id).setIssuedAt(now).setSubject(subject)
                .setIssuer(issuer);
        if (!CheckObjectUtils.isNullOrEmpty(authories)) {
            builder.claim(AUTHORITIES_KEY, authories);
        }
        if (!CheckObjectUtils.isNullOrEmpty(loginUserData)) {
            builder.claim(LOGIN_USER_DATA_KEY, loginUserData);
        }

        builder.signWith(signatureAlgorithm, signingKey);

        //if it has been specified, let's add the expiration
        if (ttlMillis >= 0) {
            long expMillis = nowMillis + ttlMillis;
            Date exp = new Date(expMillis);
            builder.setExpiration(exp);
        }
        LOGGER.info("createJWT process id=" + id + ";issuer=" + ";subject=" + subject + ";time(ms)="
                + (System.currentTimeMillis() - startTime));
        //Builds the JWT and serializes it to a compact, URL-safe string        
        String token = builder.compact();
        LOGGER.info("createJWT end id=" + id + ";issuer=" + ";subject=" + subject + ";time(ms)="
                + (System.currentTimeMillis() - startTime));
        return token;
    }

JsonWebTokenRestApi<Long> jwtApi = new JsonWebTokenRestApiFactory(
                JsonWebTokenRestApiFactory.JWT_JJWT).getJsonWebTokenByType();
        String jwt = jwtApi.createJWT(null, null, "vinhhc_vsc", null, null, 18000);

My console log:

createJWT id=null;issuer=;subject=vinhhc_vsc
createJWT process id=null;issuer=;subject=vinhhc_vsc;time(ms)=151
createJWT end id=null;issuer=;subject=vinhhc_vsc;time(ms)=664

Thanks!

What does your maven or gradle configuration look like? Did you follow the Installation instructions ?

Please do not change the focus of this ticket which is specifically about compact() performance. If you have general purpose questions about JJWT and you don’t know if it is actually a bug, please ask them on StackOverflow.com and use the jjwt tag. Thanks!

I’ll try and answer you soon. Thank!
