通过实现自定义TrustStrategy,我已经能够让 HttpClient 使用自定义 weblogic 信任存储证书进行 SSL 连接:
import sun.security.provider.certpath.X509CertPath;
import weblogic.security.pk.CertPathValidatorParameters;
import java.security.InvalidAlgorithmParameterException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertPath;
import java.security.cert.CertPathParameters;
import java.security.cert.CertPathValidator;
import java.security.cert.CertPathValidatorException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.Arrays;
public class WeblogicSSLTrustStrategy implements TrustStrategy {
@Override
public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
validator = CertPathValidator.getInstance("WLSCertPathValidator");
CertPath certPath = new X509CertPath(Arrays.asList(chain));
// supply here the weblogic realm name, configured in weblogic console
// "myrealm" is the default one
CertPathParameters params = new CertPathValidatorParameters("myrealm", null, null);
try {
validator.validate(certPath, params);
} catch (CertPathValidatorException e) {
throw new CertificateException(e);
} catch (InvalidAlgorithmParameterException e) {
throw new CertificateException(e);
}
return true;
}
}
此代码基于Weblogic 文档。该策略可以通过 SSLSocketFactory 传递给 HttpClient:
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", 80, PlainSocketFactory.getSocketFactory()));
SSLSocketFactory sslSocketFactory = new SSLSocketFactory(new WeblogicSSLTrustStrategy());
schemeRegistry.register(new Scheme("https", 443, sslSocketFactory));
PoolingClientConnectionManager connectionManager = new PoolingClientConnectionManager(schemeRegistry);
DefaultHttpClient httpClient = new DefaultHttpClient(connectionManager);
唯一未知的参数是 Weblogic Realm 名称,它可以取自 Weblogic JMX API,也可以简单地预先配置。这样就不需要实例化信任存储或重新配置 Weblogic 启动参数。
