java.lang.IllegalArgumentException: JWT string argument cannot be null or empty 这个异常信息表明,在Java程序中处理JWT(JSON Web Token)时,提供的JWT字符串参数为空(empty)或null。这通常发生在尝试解析、验证或处理JWT时,如果传入的字符串不符合要求,就会抛出此异常。下面我将根据提供的tips,逐一分析和解答:...
String authHeader = request.getHeader(jwtTokenUtil.getHeader()); try { if (authHeader != null && StringUtils.isNotEmpty(authHeader)) { String username = jwtTokenUtil.getUsernameFromToken(authHeader); jwtTokenUtil.validateToken(authHeader);//验证令牌 if (username != null && SecurityContextHol...
