I am watching durgesh sirs video, there I find code that wont working
@Component
public class JwtHelper {
//requirement :
public static final long JWT_TOKEN_VALIDITY = 5 * 60 * 60;
// public static final long JWT_TOKEN_VALIDITY = 60;
private String secret = "afafasfafafasfasfasfafacasdasfasxASFACASDFACASDFASFASFDAFASFASDAADSCSDFADCVSGCFVADXCcadwavfsfarvf";
//retrieve username from jwt token
public String getUsernameFromToken(String token) {
return getClaimFromToken(token, Claims::getSubject);
}
//retrieve expiration date from jwt token
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);
}
//for retrieveing any information from token we will need the secret key
private Claims getAllClaimsFromToken(String token) {
return Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();
}
//check if the token has expired
private Boolean isTokenExpired(String token) {
final Date expiration = getExpirationDateFromToken(token);
return expiration.before(new Date());
}
//generate token for user
public String generateToken(UserDetails userDetails) {
Map<String, Object> claims = new HashMap<>();
return doGenerateToken(claims, userDetails.getUsername());
}
//while creating the token -
//1. Define claims of the token, like Issuer, Expiration, Subject, and the ID
//2. Sign the JWT using the HS512 algorithm and secret key.
//3. According to JWS Compact Serialization(https://tools.ietf.org/html/draft-ietf-jose-json-web-signature-41#section-3.1)
// compaction of the JWT to a URL-safe string
private String doGenerateToken(Map<String, Object> claims, String subject) {
return Jwts.builder().setClaims(claims).setSubject(subject).setIssuedAt(new Date(System.currentTimeMillis()))
.setExpiration(new Date(System.currentTimeMillis() + JWT_TOKEN_VALIDITY * 1000))
.signWith(SignatureAlgorithm.HS512, secret).compact();
}
//validate token
public Boolean validateToken(String token, UserDetails userDetails) {
final String username = getUsernameFromToken(token);
return (username.equals(userDetails.getUsername()) && !isTokenExpired(token));
}
}
this is the copied code in getAllClimsFromToken class ".parseClaimsJws(token)" giving me error Cannot resolve method 'parseClaimsJws' in 'JwtParserBuilder'
