io.jsonwebtoken.UnsupportedJwtException: Signed Claims JWSs are not supported

Question

I just added Jwt to my application. When I'm trying to send get request via postman which require authorization, then I've got following error:

io.jsonwebtoken.UnsupportedJwtException: Signed Claims JWSs are not supported.

I'm sending in body "Authorization" as a Header and "Bearer token-value" as a Value.

Have anyone idea how to solve that?

Here is my jwt class:

@Service
public class JwtUtil {

private String SECRET_KEY = "secret";

public String extractUsername(String token) {
    return extractClaim(token, Claims::getSubject);
}

public Date extractExpiration(String token) {
    return extractClaim(token, Claims::getExpiration);
}

public <T> T extractClaim(String token, Function<Claims, T> claimsResolver) {
    final Claims claims = extractAllClaims(token);
    return claimsResolver.apply(claims);
}

public Claims extractAllClaims(String token) {
    return Jwts.parser().setSigningKey(SECRET_KEY).parseClaimsJwt(token).getBody();
}

public Boolean isTokenExpired(String token) {
    return extractExpiration(token).before(new Date());
}

public String generateToken(UserDetails userDetails) {
    Map<String, Object> claims = new HashMap<>();
    return createToken(claims, userDetails.getUsername());
}

public String createToken(Map<String, Object> claims, String subject) {
    return Jwts.builder()
            .setClaims(claims)
            .setSubject(subject)
            .setIssuedAt(new Date(System.currentTimeMillis()))
            .setExpiration(new Date(System.currentTimeMillis() + 1000 * 60 * 60 * 10))
            .signWith(SignatureAlgorithm.HS256, SECRET_KEY).compact();
}

public Boolean validateToken(String token, UserDetails userDetails) {
    final String userName = extractUsername(token);
    return (userName.equals(userDetails.getUsername()) && !isTokenExpired(token));
}

}

and here is my filter:

@Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
    final String authorizationHeader = httpServletRequest.getHeader("Authorization");

    String userName = null;
    String jwt = null;

    if (authorizationHeader != null && authorizationHeader.startsWith("Bearer")) {
        jwt = authorizationHeader.substring(7);
        userName = jwtUtil.extractUsername(jwt);
    }

    if (userName != null && SecurityContextHolder.getContext().getAuthentication() == null) {
        UserDetails userDetails = this.myUserDetailsService.loadUserByUsername(userName);

        if (jwtUtil.validateToken(jwt, userDetails)) {
            UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken =
                    new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
            usernamePasswordAuthenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(httpServletRequest));

            SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
        }
    }
    filterChain.doFilter(httpServletRequest, httpServletResponse);
}

Answer 1

You should use parseClaimsJws() instead of parseClaimsJwt() to verify the JWS (JWT with signature) :

Jwts.parser()
    .setSigningKey(SECRET_KEY)
    .parseClaimsJws(token)
    .getBody();
