java - 如何将字符串转换为 ECDH PublicKey 并检查其连接性

Question

我正在使用JavawithBouncy Castle将服务器端转换string_1为ECDH PublicKey，然后将其转换PublicKey为string_2以检查代码的正确性，但是string_1andstring_2不同，我不知道哪里出了问题。

String key ="BJNiB1+k2n2hiYZccfwGE87mbo5+29l+PFfKzO72tvDmXCAT4QtxqqgX2vUi5go1+MpjJCFyBmIfv5jcsOo9fo3cd/v2jwZAyh2IHh7NHWkA6PFip6el2rNfvyNCd5eN6Q==";
System.out.println("server key:" + key);

byte[] keyBytes = Base64.decodeBase64(key.getBytes("utf-8"));
ECNamedCurveParameterSpec spec = ECNamedCurveTable.getParameterSpec("secp384r1");
KeyFactory kf = KeyFactory.getInstance("ECDH", new BouncyCastleProvider());
ECNamedCurveSpec params = new ECNamedCurveSpec("secp384r1", spec.getCurve(), spec.getG(), spec.getN());
ECPoint point =  ECPointUtil.decodePoint(params.getCurve(), keyBytes);

ECPublicKeySpec pubKeySpec1 = new ECPublicKeySpec(point, params);
PublicKey pk = kf.generatePublic(pubKeySpec1);
System.out.println("convert Key*: " + Base64.encodeBase64String(pk.getEncoded()));

server key和convert key不一样，找不到原因，求帮助！
