我使用 lib JJWT 0.9.0 来生成 Token。我写了日志代码段生成令牌，我看到函数 compact() 运行非常慢 (664 -151 = 513(ms)) 。如何使函数 compact() 运行得更快或如何更快地生成令牌？我使用JDK7。
我的代码：
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);
我的控制台日志：
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
谢谢！
