Java io.jsonwebtoken.MalformedJwtException:无法读取JSON值: - java

我编写了以下函数来解析声明：

  public Claims getAllClaimsFromToken(String token) {
    return Jwts.parser().setSigningKey(config.getJwtSecret()).parseClaimsJws(token).getBody();
}

当我尝试使用以下字符串调用该函数时：

yJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJicGF3YW4iLCJyb2xlIjpudWxsLCJlbmFibGUiOm51bGwsImV4cCI6MTUzNDgyMzUyNSwiaWF0IjoxNTM0Nzk0NzI1fQ.65PPknMebR53ykLm-EBIunjFJvlV-vL-pfTOtbBLtnQ

我收到以下错误：

java大神给出的解决方案

您发布的字符串不是有效的JWT。更具体地说，标头部分（第一个.之前的部分）缺少e，这会在解析时导致错误。

添加e后，您的解码令牌看起来像这样：

{
  "alg": "HS256"
}
{
  "sub": "bpawan",
  "role": null,
  "enable": null,
  "exp": 1534823525,
  "iat": 1534794725
}

java:继承 - java

有哪些替代继承的方法？ java大神给出的解决方案 有效的Java：偏重于继承而不是继承。 （这实际上也来自“四人帮”）。他提出的理由是，如果扩展类未明确设计为继承，则继承会引起很多不正常的副作用。例如，对super.someMethod()的任何调用都可以引导您通过未知代码的意外路径。取而代之的是，持有对本来应该扩展的类的引用，然后委托给它。这是与Eric…
