java - 通过SSL连接到网站时出错

早上好，

我正在尝试使用SSL连接到站点，并且始终收到相同的异常（javax.net.ssl.SSLException：收到致命警报：意外消息）。我用站点证书创建一个信任库，并在运行时加载它们。这是代码：

import java.net.URL;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLSession;
import javax.net.ssl.X509TrustManager;

public class SSLTest {

public static void main(String [] args) throws Exception {
    System.setProperty("javax.net.debug" , "ssl");
    System.setProperty("javax.net.ssl.trustStorePassword","123456");
    System.setProperty("javax.net.ssl.trustStore","C:\\Projectos\\GapM\\WebServiceTes\\src\\truststore.jks");

    URL url = new URL("https://www.segurnet.pt");
    HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
    conn.setHostnameVerifier(new HostnameVerifier() {
        public boolean verify(String arg0, SSLSession arg1) {
            return true;
        }
    });
    System.out.println(conn.getResponseCode());
    System.out.println(conn.getResponseMessage());

    conn.disconnect();
}

private static class DefaultTrustManager implements X509TrustManager {

    public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}

    public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }

}

}

这就是我得到的：

keyStore is :
keyStore type is : jks
keyStore provider is :
init keystore
init keymanager of type SunX509
trustStore is: C:\Projectos\GapM\WebServiceTest\src\truststore.jks
trustStore type is : jks
trustStore provider is :
init truststore

最佳答案

我怀疑您需要强制其使用SSLv3。

这将失败：

openssl s_client -connect www.segurnet.pt:443

鉴于此有效：

openssl s_client -ssl3 -connect www.segurnet.pt:443

如果可能，更好的解决方案是让远程端正确配置其站点。他们目前拥有的不是很安全。
