我的问题是我在java iso客户端和测试服务器之间有ssl连接。连接正常，握手没问题，但服务器收到错误的数据。
正如我在日志服务器中看到的那样，在一次读取操作期间只接收到部分数据，并且输入流中也存在一些奇怪的数据 - 可能与证书信息有关。
请注意，如果没有ssl，此客户端和服务器可以正常运行。此外，当我通过java keyTool创建jks标准证书时，一切正常，问题不会发生。
但是当我处理x509问题时，无论我是通过从cmd生成jks还是使用下面的代码在代码中生成jks，都将证书作为服务器jvm的参数发送。连接和握手总是正常，但输入流中的数据已被破坏。
这是我如何使用boucycastle库获得证书。客户端和服务器几乎相同
private SSLServerSocketFactory handleCertificate() throws KeyManagementException, KeyStoreException, NoSuchAlgorithmException, CertificateException, IOException, UnrecoverableKeyException {
Security.addProvider(new BouncyCastleProvider());
PEMReader pr = new PEMReader(new FileReader("p.pem"));
X509CertificateObject cert = (X509CertificateObject) pr.readObject();
PEMReader pr2 = new PEMReader(new FileReader("klient.cer"));
X509CertificateObject cert2 = (X509CertificateObject) pr2.readObject();
PEMReader kr = new PEMReader(new FileReader("001.key"),
new PasswordFinder() {
public char[] getPassword() {
return "password".toCharArray();
}
});
KeyStore trustKeys = KeyStore.getInstance("JKS");
trustKeys.load(null, "".toCharArray());
trustKeys.setCertificateEntry("1", cert);
KeyStore ksKeys = KeyStore.getInstance("JKS");
ksKeys.load(null, "password".toCharArray());
ksKeys.setCertificateEntry("1", cert2);
org.bouncycastle.jce.provider.JCERSAPrivateCrtKey key;
Object PK = kr.readObject();
if (PK instanceof KeyPair) {
key = (JCERSAPrivateCrtKey) ((KeyPair) PK).getPrivate();
} else {
key = (JCERSAPrivateCrtKey) PK;
}
ksKeys.setKeyEntry("1", key, "password".toCharArray(), new Certificate[] { cert2 });
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ksKeys, "password".toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(trustKeys);
SSLContext sslContext = SSLContext.getInstance("SSLv3");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), new java.security.SecureRandom());
SSLServerSocketFactory factory = sslContext.getServerSocketFactory();
return factory;
}

size = responseSize;
} catch (Exception int_e) {
log.debug("Error of message lenth numbering: ", int_e);

答案 0 :(得分：3)
常见问题。您忽略了read()在某一点返回的结果，并假设它填充了长度缓冲区，然后如果下一次读取没有返回完全相同的字节数，那么您也忽略了实际返回的字节数。您需要将read()返回的结果存储到变量中，并且：
其他问题：
此处的Socket.isConnected()测试毫无意义。如果对等方断开连接，它将不会神奇地变为错误。您必须通过从read()获取-1，从null获取readLine(),等来检测到这一点。
同样socket == null测试。它必须是非null，否则你会在socket.getOutputStream().
您每次都在创建新的BufferedOutputStream。你应该在套接字的生命周期中使用一个。
