mina 框架如何发送字节数组

[playboylee]

mina 框架用来做NIO,挺方便,但是如何才可以发送字节数组呢?接收没问题的.

小弟是这样做的
int blen = Pkg.createLoginRespPackage(1).length;
System.out.println("------------------------> len:" + blen );
ByteBuffer buf = ByteBuffer.allocate( blen ) ;
if(buf!=null){
System.out.println("send...");
//buf.clear();
//bb.get(Pkg.createLoginRespPackage(1));
buf.put( Pkg.createLoginRespPackage(1) );
//buf.put((byte) '.');
buf.flip();
//session.write(bb.duplicate()); //发送验证包
session.write(buf); //发送验证包
//buf.clear();
}

但是出现如下异常:

java.lang.IllegalStateException: Don't know how to handle message of type 'java.nio.HeapByteBuffer'. Are you missing a protocol encoder?

请懂MINA框架的朋友帮忙，MINA是好框架，但发不了字节数组吗？

已经自己解决,需要者留言

能告诉我你是怎么解决的吗?

哥们告诉我一下怎么发送byte数组，还有就是 你的客户端和服务器端都是用的什么过滤器，为什么mina里面不用过滤器就只能够建立连接却不能够进行数据的交互。？？？我的邮箱[e-mail] 谢谢了

[yukikaze]

我也想知道，邮箱是[e-mail]
谢谢

好啊！ 我为什么总报下面的异常啊。 请问下如何维持多个客户端的连接啊？？ 急。。

IoBuffer b = IoBuffer.allocate(100);
b.putShort((short) 18);// len
String str ="Hello";
ByteArrayOutputStream outputPacket = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(outputPacket);
dos.writeUTF(str);
dos.flush();
b.put(outputPacket.toByteArray());
b.flip();
session.write(b);

没有设置编码的原因，你加上这句试试：
NioSocketAcceptor acceptor = new NioSocketAcceptor();
acceptor.getFilterChain().addLast("codec", new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("UTF-8"))));
