使用httpClient可以发送，具体的可以参考下面的代码

SSLClient类，继承至HttpClient

import java.security.cert.X509Certificate

import javax.net.ssl.SSLContext

import javax.net.ssl.TrustManager

import javax.net.ssl.X509TrustManager

import org.apache.http.conn.ClientConnectionManager

import org.apache.http.conn.scheme.Scheme

import org.apache.http.conn.scheme.SchemeRegistry

import org.apache.http.conn.ssl.SSLSocketFactory

import org.apache.http.impl.client.DefaultHttpClient

//用于进行Https请求的HttpClient

public class SSLClient extends DefaultHttpClient{

public SSLClient() throws Exception{

        super()

        SSLContext ctx = SSLContext.getInstance("TLS")

        X509TrustManager tm = new X509TrustManager() {

                @Override

                public void checkClientTrusted(X509Certificate[] chain,

                        String authType) throws CertificateException {

                }

                @Override

                public void checkServerTrusted(X509Certificate[] chain,

                        String authType) throws CertificateException {

                }

                @Override

                public X509Certificate[] getAcceptedIssuers() {

                    return null

                }

        }

        ctx.init(null, new TrustManager[]{tm}, null)

        SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER)

        ClientConnectionManager ccm = this.getConnectionManager()

        SchemeRegistry sr = ccm.getSchemeRegistry()

        sr.register(new Scheme("https", 443, ssf))

    }

}
