springboot使用jwt实现token

public class Tooken {

private static final long EXPIRE_TIME = 15*60*1000;

private static final String TOKEN_SECRET = "123465";
/**
 * 签发JWT
 * @param account
 * @param userId
 * @return  String
 *
 */
public static String createJWT(String account, String userId) {
    Algorithm algorithm = Algorithm.HMAC256(TOKEN_SECRET);
    long nowMillis = System.currentTimeMillis()+EXPIRE_TIME;
    Date now = new Date(nowMillis);
    Map<String,Object> header = new HashMap<>(2);
    header.put("typ","JWT");
    header.put("alg","HS256");
    String token = JWT.create().withHeader(header)
            .withClaim("account",account)
            .withClaim("userId",userId)
            .withExpiresAt(now)
            .sign(algorithm);
    return token;
}
/**

        return true;
    }catch (Exception e){
