循环读取输入流的出现
java.lang.NegativeArraySizeException怎么处理?
public class recv {
public static void main(String[] args) {
recv atestprocesse=new recv();
}
public recv() {
ServerSocket serversocket=null;
Socket so=null;
OutputStream output=null;
InputStream input=null;
SGIP_Command command=null;
try {
serversocket=new ServerSocket(8809);
System.out.println("等待接收");
so=serversocket.accept();
System.out.println("接收完毕");
System.out.println("New connection accepted "
+ so.getInetAddress() + ":" + so.getPort());
command=new SGIP_Command();
SGIP_Command tmpCMD=null;
Deliver deliver=null;
DeliverResp deliverresp = null;
Report report=null;
ReportResp reportresp=null;
Userrpt userrpt = null;
UserrptResp userrptresp = null;
Bind active=null;
Unbind term=null;
BindResp resp=null;
UnbindResp Unresp=null;
boolean loop=true;
while(loop)
{
input=new DataInputStream(so.getInputStream());
output=new DataOutputStream(so.getOutputStream());
tmpCMD=command.read(input);//接收sgip消息
System.out.println( tmpCMD.getTotalLength());
switch (command.getCommandID())
{
case SGIP_Command.ID_SGIP_BIND :
{
active=(Bind)tmpCMD;//强制转换
int result=active.readbody();//解包
System.out.println(tmpCMD.getTotalLength());
System.out.println(tmpCMD.getCommandID());
System.out.println(tmpCMD.getSeqno_1());
System.out.println(tmpCMD.getSeqno_2());
System.out.println(tmpCMD.getSeqno_3());
System.out.println(active.GetLoginType());
System.out.println(active.GetLoginName());
System.out.println(active.GetLoginPassword());
resp=new BindResp(352101,//node id 3+CP_id
0);//result
resp.SetResult(1);
resp.write(output);
System.out.println("resp完成");
break;
}
这是部分代码,测试的时候每次下发短息的回复报告都是出现
等待接收
接收完毕
New connection accepted /192.168.0.119:2973

resp完成

NegativeArraySizeException应该是数据流到最后-1标志结尾,但是程序还是读取导致的,我处理了,还是不行,不知道怎么办?
------解决方案--------------------
try块后面的代码没有贴出来。
其实这种问题无需问的,你找到报异常的行,Debug一下就行了。
