1. SSLServer.java

package ssl;import java.io.FileInputStream;import java.io.InputStream;import java.net.ServerSocket;import java.net.Socket;import java.security.KeyStore;import java.util.logging.Logger;import javax.net.ServerSocketFactory;import javax.net.ssl.KeyManagerFactory;import javax.net.ssl.SSLContext;import javax.net.ssl.SSLServerSocket;public class SSLServer {private String SERVER_KEY_STORE = "/D:/Projects/J2EE/JDK/src/ssl/keystore/server_ks";      private String SERVER_KEY_STORE_PASSWORD = "123123";          private Logger logger = Logger.getLogger(this.getClass().getName());private SSLServerSocket createSSLServerSocket() throws Exception{// whether enable the debug mode    System.setProperty("javax.net.debug", "ssl,handshake");  System.setProperty("javax.net.ssl.trustStore", SERVER_KEY_STORE);          SSLContext context = SSLContext.getInstance("TLS");                    KeyStore ks = KeyStore.getInstance("jceks");          ks.load(new FileInputStream(SERVER_KEY_STORE), null);          KeyManagerFactory kf = KeyManagerFactory.getInstance("SunX509");          kf.init(ks, SERVER_KEY_STORE_PASSWORD.toCharArray());        context.init(kf.getKeyManagers(), null, null);                  ServerSocketFactory factory = context.getServerSocketFactory();          ServerSocket serverSocket = factory.createServerSocket(8443);          SSLServerSocket sslServerSocket =  (SSLServerSocket) serverSocket;        // set whether need the client authentication//        sslServerSocket.setNeedClientAuth(true);         return sslServerSocket;}private void start() throws Exception{SSLServerSocket sslServerSocket= createSSLServerSocket();while(true){try{Socket socket = sslServerSocket.accept();InputStream is = socket.getInputStream();byte[] bytes = new byte[Short.MAX_VALUE];int len = -1;while((len = is.read(bytes))>0){logger.info(new String(bytes,0,len));if(len<bytes.length){break;}}socket.getOutputStream().write("server balabala ... ".getBytes());socket.close();}catch(Exception e){e.printStackTrace();}}}    public static void main(String[] args)throws Exception {new SSLServer().start();}}

 

2. SSLClient.java

package ssl;import java.io.BufferedReader;import java.io.FileInputStream;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.Socket;import java.security.KeyStore;import java.util.logging.Logger;import javax.net.SocketFactory;import javax.net.ssl.KeyManagerFactory;import javax.net.ssl.SSLContext;import javax.net.ssl.SSLSocketFactory;public class SSLClient {private static String CLIENT_KEY_STORE = "/D:/Projects/J2EE/JDK/src/ssl/keystore/client_ks";  private static String CLIENT_KEY_STORE_PASSWORD = "456456";  private Logger logger = Logger.getLogger(this.getClass().getName());private Socket createNonAuthenticationSocket()throws Exception{System.setProperty("javax.net.ssl.trustStore", CLIENT_KEY_STORE);          SocketFactory sf = SSLSocketFactory.getDefault();          Socket s = sf.createSocket("localhost", 8443);          return s;  }private Socket createAuthenticationSocket() throws Exception{System.setProperty("javax.net.ssl.trustStore", CLIENT_KEY_STORE);          SSLContext context = SSLContext.getInstance("TLS");          KeyStore ks = KeyStore.getInstance("jceks");          ks.load(new FileInputStream(CLIENT_KEY_STORE), null);          KeyManagerFactory kf = KeyManagerFactory.getInstance("SunX509");          kf.init(ks, CLIENT_KEY_STORE_PASSWORD.toCharArray());          context.init(kf.getKeyManagers(), null, null);                    SocketFactory factory = context.getSocketFactory();          Socket s = factory.createSocket("localhost", 8443);          return s;  }private void connect()throws Exception{   Socket s = createNonAuthenticationSocket();  //     Socket s = createAuthenticationSocket();          PrintWriter writer = new PrintWriter(s.getOutputStream());         BufferedReader reader = new BufferedReader(new InputStreamReader(s.getInputStream()));         writer.println("hello");         writer.flush();         logger.info(reader.readLine());         s.close();  }    public static void main(String[] args) throws Exception {      new SSLClient().connect();    }  }

 

PS : 解压 client_server_keystore.rar, 然后分别拷贝到指定的如下位置.

SERVER_KEY_STORE = "/D:/Projects/J2EE/JDK/src/ssl/keystore/server_ks",

CLIENT_KEY_STORE = "/D:/Projects/J2EE/JDK/src/ssl/keystore/client_ks".

然后分别运行SSLServer，SSLClient。
