怎样将Apache Mina中的IoBuffer转换为String

Answer 1

Java代码
/**
* 将byte[]转换成string
* @param butBuffer
*/
public static String byteToString(byte [] b)
{
StringBuffer stringBuffer = new StringBuffer();
for (int i = 0; i < b.length; i++)
{
stringBuffer.append((char) b [i]);
}
return stringBuffer.toString();
}

/**
* 将bytebuffer转换成string
* @param str
*/
public static IoBuffer stringToIoBuffer(String str)
{

byte bt[] = str.getBytes();

IoBuffer ioBuffer = IoBuffer.allocate(bt.length);
ioBuffer.put(bt, 0, bt.length);
ioBuffer.flip();
return ioBuffer;
}
/**
* 将IoBuffer转换成string
* @param str
*/
public static IoBuffer byteToIoBuffer(byte [] bt,int length)
{

IoBuffer ioBuffer = IoBuffer.allocate(length);
ioBuffer.put(bt, 0, length);
ioBuffer.flip();
return ioBuffer;
}
/**
* 将IoBuffer转换成byte
* @param str
*/
public static byte [] ioBufferToByte(Object message)
{
if (!(message instanceof IoBuffer))
{
return null;
}
IoBuffer ioBuffer = (IoBuffer)message;
byte[] b = new byte[ioBuffer.limit()];
ioBuffer.get(b);
return b;
}
/**
* 将IoBuffer转换成string
* @param butBuffer
*/
public static String ioBufferToString(Object message)
{
if (!(message instanceof IoBuffer))
{
return "";
}
IoBuffer ioBuffer = (IoBuffer) message;
byte[] b = new byte [ioBuffer.limit()];
ioBuffer.get(b);
StringBuffer stringBuffer = new StringBuffer();

for (int i = 0; i < b.length; i++)
{

stringBuffer.append((char) b [i]);
}
return stringBuffer.toString();
}
