天堂2游戏登陆服务器源码分析<1>
???? 天堂2使用国外开源游戏引擎L2JGameServer作为服务端游戏引擎,最近几天看了一下其源码,在此分享个人的经验。其主类为L2LoginServer:
?
? 我们就从它的构造函数开始吧:
?
//读取日志配置文件,配置日志
InputStream is = null;
??try
??{
???is = new FileInputStream(new File(LOG_NAME));
???LogManager.getLogManager().readConfiguration(is);
???is.close();
??}
??catch (IOException e)
??{
???e.printStackTrace();
??}
?
//读取其他游戏配置信息,如服务器灾难预防配置,数据库连接信息等,游戏技能等
Config.load();
?
?
//初始化mysql数据库连接
try
??{
???L2DatabaseFactory.getInstance();
??}
??catch (SQLException e)
??{
???_log.log(Level.SEVERE, "FATAL: Failed initializing database. Reason: " + e.getMessage(), e);
???System.exit(1);
??}
这个一看就知道,我就不用说了:
?
try
??{
???LoginController.load();
??}
??catch (GeneralSecurityException e)
??{
???_log.log(Level.SEVERE, "FATAL: Failed initializing LoginController. Reason: " + e.getMessage(), e);
???System.exit(1);
??}
?
?
/**生成RSA加密解密密钥在通信过程使用
:生成密钥对,发送信息之前加密,收到信息时候解密
?
private LoginController() throws GeneralSecurityException
?{
??_log.info("Loading LoginController...");
??
??_hackProtection = new FastMap<InetAddress, FailedLoginAttempt>();
??
??_keyPairs = new ScrambledKeyPair[10];
??
??KeyPairGenerator keygen = null;
??
??keygen = KeyPairGenerator.getInstance("RSA");
??RSAKeyGenParameterSpec spec = new RSAKeyGenParameterSpec(1024, RSAKeyGenParameterSpec.F4);
??keygen.initialize(spec);
??
??//generate the initial set of keys
??for (int i = 0; i < 10; i++)
??{
???_keyPairs[i] = new ScrambledKeyPair(keygen.generateKeyPair());
??}
??_log.info("Cached 10 KeyPairs for RSA communication");
??
??testCipher((RSAPrivateKey) _keyPairs[0]._pair.getPrivate());
??
??// Store keys for blowfish communication
??generateBlowFishKeys();
??
??_purge = new PurgeThread();
??_purge.setDaemon(true);
??_purge.start();
?}
?
?
?
?
?
?
?
?
?
?
try
??{
???GameServerTable.load();
??}
??catch (GeneralSecurityException e)
??{
???_log.log(Level.SEVERE, "FATAL: Failed to load GameServerTable. Reason: " + e.getMessage(), e);
???System.exit(1);
??}
?
//读取服务器信息以及生成RSA密钥
public GameServerTable() throws SQLException, NoSuchAlgorithmException, InvalidAlgorithmParameterException
?{
??loadServerNames();
??_log.info("Loaded " + _serverNames.size() + " server names");
??
??loadRegisteredGameServers();
??_log.info("Loaded " + _gameServerTable.size() + " registered Game Servers");
??
??loadRSAKeys();
??_log.info("Cached " + _keyPairs.length + " RSA keys for Game Server communication.");
?}
?
//服务器收到信息时候使用私钥解密,发送数据时候私钥加密
//客户端使用公钥解密收到数据,使用公钥加密要发送数据
?private void loadRSAKeys() throws NoSuchAlgorithmException, InvalidAlgorithmParameterException
?{
??KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA");
??RSAKeyGenParameterSpec spec = new RSAKeyGenParameterSpec(512, RSAKeyGenParameterSpec.F4);
??keyGen.initialize(spec);
??
//生成10个KeyPair,发送数据时候随机选择一个私钥加密
??_keyPairs = new KeyPair[KEYS_SIZE];
??for (int i = 0; i < KEYS_SIZE; i++)
??{
???_keyPairs[i] = keyGen.genKeyPair();
??}
?}
?
//加载配置的禁止访问IP
loadBanFile();
