示例1: Gerate
public static String Gerate(String issuer, int idSubject, int hours) {
//The JWT signature algorithm we will be using to sign the token
SignatureAlgorithm signatureAlgorithm = SignatureAlgorithm.HS256;
//Hours to milliseconds
long ttlMillis = hours * 3600000;
String subject = String.valueOf(idSubject);
long nowMillis = System.currentTimeMillis();
Date now = new Date(nowMillis);
//We will sign our JWT with our ApiKey secret
byte[] apiKeySecretBytes = DatatypeConverter.parseBase64Binary(Parameters.TOKENKEY);
Key signingKey = new SecretKeySpec(apiKeySecretBytes, signatureAlgorithm.getJcaName());
//Let's set the JWT Claims
JwtBuilder builder = Jwts.builder().setIssuedAt(now)
.setSubject(subject)
.setIssuer(issuer)
.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);
}
//Builds the JWT and serializes it to a compact, URL-safe string
return builder.compact();
