我有一个问题与 JWT 认证令牌。当我第一次用postman测试登录时，它给了我令牌，但在重新启动intelij后，我在postman和intelij中得到了403禁止错误（JWT签名与本地计算的签名不匹配。JWT的有效性不能Assert，也不应该被信任。）（这里我用 Postman）。这是我的代码

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

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

    public Boolean hasClaim(String token, String claimName) {
        final Claims claims = extractAllClaims(token);
        return claims.get(claimName) != null;
    }

    public <T> T extractClaim(String token, Function<Claims, T> claimsResolver) {

在此处键入

问题可能来自以下事实：您正在使用.signWith(SignatureAlgorithm.HS256,Secret)对令牌进行签名，并且为了在extractAllClaims中获得声明，您仅直接使用机密，因此它无法检索适当的信息来验证令牌Jwts.parser().setSigningKey(Secret).parseClaimsJws(token).getBody();
另外，我想指出的是，根据文档，您用于签署令牌的方法已被弃用，请查看文档/Parser Doc，您可以进行适当的调整。同样作为参考，你可以把静态秘密检查为byte[]，Key或String？
