信任过期的证书[重复]

Question

这个问题已经在这里有了答案：

• java-忽略过期的ssl证书 3个答案

与具有过期证书的https服务器通信时，我的客户端失败并出现以下错误。 当我们正在等待通过更新将其修复在服务器端时，我想知道是否可以通过将过期的证书添加到我们自己的信任库中来传递此错误？ 这使我们可以在等待证书更新的同时获得一些测试时间。

使用以下代码信任所有证书。 注意：请勿在生产中使用

    try {
        SSLContext ctx = SSLContext.getInstance("TLS");
        ctx.init(new KeyManager[0], new TrustManager[] { new X509TrustManager() {
            @Override
            public void checkClientTrusted(X509Certificate[] x509Certificates, String name) throws CertificateException {}

            @Override
            public void checkServerTrusted(X509Certificate[] x509Certificates, String name) throws CertificateException {}

            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        } }, new SecureRandom());

        SSLContext.setDefault(ctx);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
