本演示例程是繼Java Tomcat SSL 服務(wù)端/客戶端雙向認證（一），密鑰庫可證書的生成腳本不再重復(fù)黏貼，僅僅是用程序來代替瀏覽器訪問服務(wù)端。
          例程中使用到了Apache HttpClient庫，版本為4.1.3
          全部依賴庫：
          commons-logging-1.1.1.jar
          httpclient-4.1.3.jar
          httpcore-4.1.4.jar
          httpmime-4.1.3.jar(上傳文件使用)

          在（一）中的程序包中創(chuàng)建一個客戶端類：HttpsClient
          HttpsClient.java
          package com.icesoft.client;

          import java.io.BufferedReader;
          import java.io.File;
          import java.io.FileInputStream;
          import java.io.InputStream;
          import java.io.InputStreamReader;
          import java.security.KeyStore;

          import org.apache.http.HttpEntity;
          import org.apache.http.HttpResponse;
          import org.apache.http.client.HttpClient;
          import org.apache.http.client.methods.HttpGet;
          import org.apache.http.conn.scheme.Scheme;
          import org.apache.http.conn.ssl.SSLSocketFactory;
          import org.apache.http.impl.client.DefaultHttpClient;
          import org.apache.http.util.EntityUtils;

          public class HttpsClient {
              
                        private static final String KEY_STORE_TYPE_JKS = "jks";
                        private static final String KEY_STORE_TYPE_P12 = "PKCS12";
                        private static final String SCHEME_HTTPS = "https";
                        private static final int HTTPS_PORT = 8443;
                        private static final String HTTPS_URL = "https://127.0.0.1:8443/HttpClientSSL/sslServlet";
                        private static final String KEY_STORE_CLIENT_PATH = "E:/ssl/client.p12";
                        private static final String KEY_STORE_TRUST_PATH = "E:/ssl/client.truststore";
                        private static final String KEY_STORE_PASSWORD = "123456";
                        private static final String KEY_STORE_TRUST_PASSWORD = "123456";

                        public static void main(String[] args) throws Exception {
                  ssl();
              }
              
                        private static void ssl() throws Exception {
                  HttpClient httpClient           = new DefaultHttpClient();
                            try {
                      KeyStore keyStore            = KeyStore.getInstance(KEY_STORE_TYPE_P12);
                      KeyStore trustStore            = KeyStore.getInstance(KEY_STORE_TYPE_JKS);
                      InputStream ksIn           = new FileInputStream(KEY_STORE_CLIENT_PATH);
                      InputStream tsIn           = new FileInputStream(new File(KEY_STORE_TRUST_PATH));
                                try {
                          keyStore.load(ksIn, KEY_STORE_PASSWORD.toCharArray());
                          trustStore.load(tsIn, KEY_STORE_TRUST_PASSWORD.toCharArray());
                      }           finally {
                                    try { ksIn.close(); } catch (Exception ignore) {}
                                    try { tsIn.close(); } catch (Exception ignore) {}
                      }
                      SSLSocketFactory socketFactory           = new SSLSocketFactory(keyStore, KEY_STORE_PASSWORD, trustStore);
                      Scheme sch           = new Scheme(SCHEME_HTTPS, HTTPS_PORT, socketFactory);
                      httpClient.getConnectionManager().getSchemeRegistry().register(sch);
                      HttpGet httpget           = new HttpGet(HTTPS_URL);
                      System.out.println(          "executing request" + httpget.getRequestLine());
                      HttpResponse response           = httpClient.execute(httpget);
                      HttpEntity entity           = response.getEntity();
                      System.out.println(          "----------------------------------------");
                      System.out.println(response.getStatusLine());
                                if (entity != null) {
                          System.out.println(          "Response content length: " + entity.getContentLength());
                          BufferedReader bufferedReader           = new BufferedReader(new InputStreamReader(entity.getContent()));
                          String text;
                                    while ((text = bufferedReader.readLine()) != null) {
                              System.out.println(text);
                          }
                          bufferedReader.close();
                      }
                      EntityUtils.consume(entity);
                  }           finally {
                      httpClient.getConnectionManager().shutdown();
                  }
              }

          }


          啟動Tomcat，運行HttpsClient，控制臺返回：


          OK，和使用瀏覽器訪問得到的結(jié)果一模一樣！

          全文完！

          為什么我的一直是“這是一個HTTPS請求，但是沒有可用的客戶端證書”？
