JAVA怎样调用https类型的webservice

public static org.apache.http.client.HttpClient wrapClient(org.apache.http.client.HttpClient base) {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
@SuppressWarnings("unused")
public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
@SuppressWarnings("unused")
public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
@Override
public void checkClientTrusted(
java.security.cert.X509Certificate[] chain,
String authType)
throws java.security.cert.CertificateException {

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

}
};
ctx.init(null, new TrustManager[] { tm }, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("https", 443, ssf));
ThreadSafeClientConnManager mgr = new ThreadSafeClientConnManager(registry);
return new DefaultHttpClient(mgr, base.getParams());
} catch (Exception ex) {
ex.printStackTrace();
return null;
}
}

初始化httpclient 的时候加上：
HttpClient client = new DefaultHttpClient();
client = WebClientDevWrapper.wrapClient(client);
HttpPost post = new HttpPost(url);
