我想访问一个托管在远程虚拟机上的https SOAP webservice url。使用HttpURLConnection访问时出现了异常。
以下是我的代码:
import javax.net.ssl.*;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
/**

public class Main
{
public static void main(String [] args)
{
try
{
URL url = new URL("https://myhost:8913/myservice/service?wsdl");
HttpURLConnection http = null;
if (url.getProtocol().toLowerCase().equals("https")) {
trustAllHosts();
HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
https.setHostnameVerifier(DO_NOT_VERIFY);
http = https;
} else {
http = (HttpURLConnection) url.openConnection();
}
String SOAPAction="";
// http.setRequestProperty("Content-Length", String.valueOf(b.length));
http.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
http.setRequestProperty("SOAPAction", SOAPAction);
http.setRequestMethod("GET");
http.setDoOutput(true);
http.setDoInput(true);
OutputStream out = http.getOutputStream();
}
catch (Exception e)
{
e.printStackTrace();
}
}
final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
private static void trustAllHosts() {
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[] {};
}
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException
{
}
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
} };
// Install the all-trusting trust manager
try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection
.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
e.printStackTrace();
}
}
}
我遇到了以下异常:

我在谷歌搜索中尝试了不同的解决方案,但它们都没有起作用。我想避免使用keytool,因为我将在不同的虚拟机上运行我的测试。
请问有人有任何解决方案吗?
