I have this class that uses JSON Web Token Support For The JVM to create and validate JWT tokens
@Componentpublic class JwtTokenUtil implements Serializable { private static final long serialVersionUID = -3301605592208950415L; private Clock clock = DefaultClock.INSTANCE; @Value("${jwt.secret}") private String secret; @Value("${jwt.expiration}") private Long expiration; public String getUsernameFromToken(String token) { return getClaimFromToken(token, Claims::getSubject); } public Date getIssuedAtDateFromToken(String token) { return getClaimFromToken(token, Claims::getIssuedAt); } public Date getExpirationDateFromToken(String token) { return getClaimFromToken(token, Claims::getExpiration); } public <T> T getClaimFromToken(String token, Function<Claims, T> claimsResolver) { final Claims claims = getAllClaimsFromToken(token); return claimsResolver.apply(claims); } private Claims getAllClaimsFromToken(String token) { return Jwts.parser() .setSigningKey(secret) .parseClaimsJws(token) .getBody(); } private Boolean isTokenExpired(String token) { final Date expiration = getExpirationDateFromToken(token); return expiration.before(clock.now()); } private Boolean isCreatedBeforeLastPasswordReset(Date created, Date lastPasswordReset) { return (lastPasswordReset != null && created.before(lastPasswordReset)); } private Boolean ignoreTokenExpiration(String token) { return false; } public String generateToken(UserDetails userDetails) { Map<String, Object> claims = new HashMap<>(); return doGenerateToken(claims, userDetails.getUsername()); } private String doGenerateToken(Map<String, Object> claims, String subject) { final Date createdDate = clock.now(); final Date expirationDate = calculateExpirationDate(createdDate); return Jwts.builder() .setClaims(claims) .setSubject(subject) .setIssuedAt(createdDate) .setExpiration(expirationDate) .signWith(SignatureAlgorithm.HS512, secret) .compact(); } public Boolean canTokenBeRefreshed(String token, Date lastPasswordReset) { final Date created = getIssuedAtDateFromToken(token); return !isCreatedBeforeLastPasswordReset(created, lastPasswordReset)&& (!isTokenExpired(token) || ignoreTokenExpiration(token)); } public String refreshToken(String token) { final Date createdDate = clock.now(); final Date expirationDate = calculateExpirationDate(createdDate); final Claims claims = getAllClaimsFromToken(token); claims.setIssuedAt(createdDate); claims.setExpiration(expirationDate); return Jwts.builder() .setClaims(claims) .signWith(SignatureAlgorithm.HS512, secret) .compact(); } public Boolean validateToken(String token, UserDetails userDetails) { User user = (User) userDetails; final String username = getUsernameFromToken(token); final Date created = getIssuedAtDateFromToken(token); return ( username.equals(user.getUsername())&& !isTokenExpired(token)&& !isCreatedBeforeLastPasswordReset(created, user.getLastPasswordResetDate()) ); } private Date calculateExpirationDate(Date createdDate) { return new Date(createdDate.getTime() + expiration * 1000); }}But I got this error when validating a token:
