當我嘗試調用 soap web 服務方法時，我遇到了這個異常。 我怎么解決這個問題？

Answer 1

我解決了這個異常，這里是 class，它幫助我解決了問題。 如果您在調用 webservice 方法時遇到此錯誤，請調用 allowSSL() 方法，然后調用您的 ws 調用方法。

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

public class FakeX509TrustManager implements X509TrustManager {

private TrustManager[] trustManagers;
private final X509Certificate[] _AcceptedIssuers = new X509Certificate[]{};

@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}

@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}

public boolean isClientTrusted(X509Certificate[] chain) {
    return true;
}

public boolean isServerTrusted(X509Certificate[] chain) {
    return true;
}

@Override
public X509Certificate[] getAcceptedIssuers() {
    return _AcceptedIssuers;
}

public void allowAllSSL() throws KeyManagementException {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    });
    SSLContext context = null;
    if (trustManagers == null) {
        trustManagers = new TrustManager[]{new FakeX509TrustManager()};
    }
    try {
        context = SSLContext.getInstance("TLS");
        context.init(null, trustManagers, new SecureRandom());
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
}

}
