Apache MINA 2.0.0-M1 的api比1.x更简单好用了，

新增加了许多filter功能，各个filter 功能在filter包下面以子目录方式存放，例如：

org.apache.mina.filter.executor.ExecutorFilter

org.apache.mina.filter.ssl.SslFilter

org.apache.mina.filter.keepalive.KeepAliveFilter

org.apache.mina.filter.compression.CompressionFilter
org.apache.mina.filter.firewall.BlacklistFilter
org.apache.mina.filter.logging.LoggingFilter

[code]

public static void main(String[] args) throws IOException, Exception {
IoAcceptor acceptor = new NioSocketAcceptor();
DefaultIoFilterChainBuilder chain = acceptor.getFilterChain();
//Utils.addServerSSLSupport(chain);
Utils.addThreadPool(chain);
// Utils.addCompress(chain);
Utils.addCodec(chain);
Utils.addLogger(chain);
SMPPServerSessionHandler handlers = new SMPPServerSessionHandler();
handlers.getHandles().put(Integer.valueOf(0×00000001),
new com.lizongbo.smpp.server.handlers.
BindReceiverHandler());
handlers.getHandles().put(Integer.valueOf(0×00000002),
new com.lizongbo.smpp.server.handlers.
BindTransmitterHandler());
handlers.getHandles().put(Integer.valueOf(0×00000004),
new com.lizongbo.smpp.server.handlers.
SubmitSMHandler());
handlers.getHandles().put(Integer.valueOf(0×00000006),
new com.lizongbo.smpp.server.handlers.
UnbindHandler());
InetSocketAddress serverAddr = new InetSocketAddress(Utils.PORT);
acceptor.setHandler(handlers);
acceptor.bind(serverAddr);
System.out.println(”Listening on port ” + Utils.PORT);
}

[/code]

spring配置的bean也有所变动

在修改代码的时候，发现以前写的smpp server例子里SMPPProtocolDecoder 存在bug，

[code]
public void decode(IoSession session, IoBuffer in, ProtocolDecoderOutput out)
throws Exception {

try {

//以前用的if判断，导致有数据包漏了。

while(in.remaining() >= 4
&& (in.remaining() >= in.getInt(in.position()))) {
byte[] b = new byte[in.getInt(in.position())];
in.get(b);
SMPPPacketpak = null;
int id = -1;
id = SMPPIO.bytesToInt(b, 4, 4);
pak = PacketFactory.newInstance(id);
if (pak != null) {
pak.readFrom(b, 0);
System.out.println(”decode:==” + pak);
out.write(pak);
}
}
} catch (BadCommandIDException ex) {
ex.printStackTrace();
}
}

[/code]

在使用AprSocketAcceptor的时候，客户端连接上来时，

服务端就出错，在网上也没搜索到这个错误码具体是什么含义。
