Question

请告诉我如何正确解析JWT令牌。我需要得到角色......

   static Authentication getAuthentication(HttpServletRequest request) {
    String token = request.getHeader(HEADER_STRING);
    if (token != null) {
        // parse the token.
        String user = Jwts.parser()
                .setSigningKey(SECRET)
                .parseClaimsJws(token.replace(TOKEN_PREFIX, ""))
                .getBody()
                .getSubject();
        Claims claims = Jwts.parser()
                .setSigningKey(SECRET)
                .parseClaimsJws(token.replace(TOKEN_PREFIX, ""))
                .getBody();
        List<String> roles = (ArrayList<String>)claims.get("roles");
        System.out.println("ROLE IS: " + roles);
        return user != null ?
                new UsernamePasswordAuthenticationToken(user, null, Collections.emptyList()) :
                null;
    }
    return null;
}

输出ROLE IS：[{authority = ROLE_ADMIN}，{authority = ROLE_USER} 如何正确地将其转换为Collection以用作UsernamePasswordAuthenticationToken中的参数。谢谢。
