您仍然可以通过实施自己的信任管理器来检查证书。我遇到了类似的问题here。我还尝试将证书添加到cacerts，但无济于事。
在您的信任管理器中，您需要显式加载证书。基本上我必须做的是这样的：
首先，我创建一个使用实际证书文件的信任管理器：
public class ValicertX509TrustManager implements X509TrustManager {
X509TrustManager pkixTrustManager;
ValicertX509TrustManager() throws Exception {
String valicertFile = "/certificates/ValicertRSAPublicRootCAv1.cer";
String commwebDRFile = "/certificates/DR_10570.migs.mastercard.com.au.crt";
String commwebPRODFile = "/certificates/PROD_10549.migs.mastercard.com.au.new.crt";
Certificate valicert = CertificateFactory.getInstance("X509").generateCertificate(this.getClass().getResourceAsStream(valicertFile));
Certificate commwebDR = CertificateFactory.getInstance("X509").generateCertificate(this.getClass().getResourceAsStream(commwebDRFile));
Certificate commwebPROD = CertificateFactory.getInstance("X509").generateCertificate(this.getClass().getResourceAsStream(commwebPRODFile));
KeyStore keyStore = KeyStore.getInstance("JKS");
keyStore.load(null, "".toCharArray());
keyStore.setCertificateEntry("valicert", valicert);
keyStore.setCertificateEntry("commwebDR", commwebDR);
keyStore.setCertificateEntry("commwebPROD", commwebPROD);
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("PKIX");
trustManagerFactory.init(keyStore);
TrustManager trustManagers[] = trustManagerFactory.getTrustManagers();
for(TrustManager trustManager : trustManagers) {
if(trustManager instanceof X509TrustManager) {
pkixTrustManager = (X509TrustManager) trustManager;
return;
}
}
throw new Exception("Couldn't initialize");
}
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
pkixTrustManager.checkServerTrusted(chain, authType);
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
pkixTrustManager.checkServerTrusted(chain, authType);
}
public X509Certificate[] getAcceptedIssuers() {
return pkixTrustManager.getAcceptedIssuers();
}
}
现在，使用这个信任管理器，我必须创建一个套接字工厂：
public class ValicertSSLProtocolSocketFactory implements ProtocolSocketFactory {
private SSLContext sslContext = null;
public ValicertSSLProtocolSocketFactory() {
super();
}
private static SSLContext createValicertSSLContext() {
try {
ValicertX509TrustManager valicertX509TrustManager = new ValicertX509TrustManager();
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, new ValicertX509TrustManager[] { valicertX509TrustManager}, null);
return context;
}
catch(Exception e) {
Log.error(Log.Context.Net, e);
return null;
}
}
private SSLContext getSSLContext() {
if(this.sslContext == null) {
this.sslContext = createValicertSSLContext();
}
return this.sslContext;
}
public Socket createSocket(String host, int port, InetAddress clientHost, int clientPort) throws IOException {
return getSSLContext().getSocketFactory().createSocket(host, port, clientHost, clientPort);
}
public Socket createSocket(final String host, final int port, final InetAddress localAddress, final int localPort, final HttpConnectionParams params) throws IOException {
if(params == null) {
throw new IllegalArgumentException("Parameters may not be null");
}
int timeout = params.getConnectionTimeout();
SocketFactory socketFactory = getSSLContext().getSocketFactory();
if(timeout == 0) {
return socketFactory.createSocket(host, port, localAddress, localPort);
}
else {
Socket socket = socketFactory.createSocket();
SocketAddress localAddr = new InetSocketAddress(localAddress, localPort);
SocketAddress remoteAddr = new InetSocketAddress(host, port);
socket.bind(localAddr);
socket.connect(remoteAddr, timeout);
return socket;
}
}
public Socket createSocket(String host, int port) throws IOException {
return getSSLContext().getSocketFactory().createSocket(host, port);
}
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException {
return getSSLContext().getSocketFactory().createSocket(socket, host, port, autoClose);
}
public boolean equals(Object obj) {
return ((obj != null) && obj.getClass().equals(ValicertSSLProtocolSocketFactory.class));
}
public int hashCode() {
return ValicertSSLProtocolSocketFactory.class.hashCode();
}
}
然后我刚刚注册了一个新协议：
Protocol.registerProtocol("vhttps", new Protocol("vhttps", new ValicertSSLProtocolSocketFactory(), 443));
PostMethod postMethod = new PostMethod(url);
for (Map.Entry<String, String> entry : params.entrySet()) {
postMethod.addParameter(entry.getKey(), StringUtils.Nz(entry.getValue()));
}
HttpClient client = new HttpClient();
int status = client.executeMethod(postMethod);
if (status == 200) {
StringBuilder resultBuffer = new StringBuilder();
resultBuffer.append(postMethod.getResponseBodyAsString());
return new HttpResponse(resultBuffer.toString(), "");
} else {
throw new IOException("Invalid response code: " + status);
}
唯一的缺点是我必须为这个特定的证书创建一个特定的协议 (vhttps)。
