public class packhead implements Serializable
{
byte[] from = new byte[16];
byte[] to = new byte[16];
int ntype;
int nlength;
}
在socket通讯的时候这么写，但是效果却达不到，
packhead headheart = new packhead();
String strHeadFrom = "javaserver";
headheart.from = strHeadFrom.getBytes();
strHeadFrom = "vcclient";
headheart.to = strHeadFrom.getBytes();
headheart.nlength = 40;
headheart.ntype = 90;
Byte_File_Object objto= new Byte_File_Object();
byte[] bufobject1 = objto.getBytesFromObject(headheart);
System.out.print("\n转换后的数据为" + bufobject1);
packhead headto = (packhead) objto.getObjectFromBytes(bufobject1);
byte[] bufobject2 = objto.getBytesFromObject(headto);
System.out.print("\n反转回来" + bufobject2);
其中使用的转化类
class Byte_File_Object {
public static Object getObjectFromBytes(byte[] objBytes) throws Exception {
if (objBytes == null || objBytes.length == 0) {
return null;
}
ByteArrayInputStream bi = new ByteArrayInputStream(objBytes);
ObjectInputStream oi = new ObjectInputStream(bi);
return oi.readObject();
}
public static byte[] getBytesFromObject(Serializable obj) throws Exception {
if (obj == null) {
return null;
}
ByteArrayOutputStream bo = new ByteArrayOutputStream();
ObjectOutputStream oo = new ObjectOutputStream(bo);
oo.writeObject(obj);
return bo.toByteArray();
}
}
转化后的数据发送到客户端是乱码，而且转换前后数据都不对应了。
