I write a server base grizzly,I write a client which send data to server and
receive response from server. I send 50 bytes data and 2k data to server
ok,but when I send 20K and 2MB data,server no response.
I view the code of grizzly,find the ByteBuffer of a workthread capity is
8192,then I modify it to 81920,then 20k data can receive by server.
If my Server set the init size of ByteBuffer is 81920,I think it would use
to much memory,who can tell me some method,will dynamic just the buffer,can
receive some bytes data ,or some MB data?
My Server's protocol parser code :
final ProtocolFilter parserProtocolFilter = new
ParserProtocolFilter() {
public ProtocolParser newProtocolParser() {
return new ProtocolParser() {
private boolean isExpectingMoreData = false;
private ByteBuffer byteBuffer;
private Request message;
public boolean hasMoreBytesToParse() {
return false;
}
public boolean isExpectingMoreData() {
return isExpectingMoreData;
}
public Object getNextMessage() {
return message;
}
public boolean hasNextMessage() {
ByteBuffer dup = byteBuffer.duplicate();
System.out.println( "byteBuffer.position2()=" +
byteBuffer.position() );
if (byteBuffer.position() == 0){
System.out.println("byteBuffer.position() ==
0");
isExpectingMoreData = true;
return false;
}
dup.flip();
if( dup.remaining()< 4 ){
isExpectingMoreData = true;
return false;
}
byte[] bs = new byte[4];
dup.get(bs);
int len= (bs[0] << 24) + (bs[1] << 16) + (bs[2] <<
8) + (bs[3] << 0);
if( dup.remaining() < len ){
isExpectingMoreData = true;
return false;
}
byte[] data = new byte[len];
dup.get( data );
try {
message = new ByteRequest(data);
} catch (Exception e) {
e.printStackTrace();
message=null;
return false;
}
return true;
}
public void startBuffer(ByteBuffer bb) {
byteBuffer = bb;
}
public boolean releaseBuffer() {
byteBuffer = null;
message = null;
return false;
}
};
}
};
