java调用dll 堆栈溢出
我在做一个RFID读卡器，在调用其中的初始化函数的时候 总归是爆出堆栈溢出的错误。
请问如何解决？ 用到了 JNA的技术 dll文件问 rfid.dll
java代码如下:
public class EcardReaderImpl {
/**
* 连接读写器
* @param port
* @return
* @throws NativeException
* @throws IllegalAccessException
*/
public String ConnectionReader(int port) throws NativeException, IllegalAccessException{
JNative n = null;
try{
//1.创建JNative对象
n = new JNative("rfid.dll","RFID_Startup");//初始化
//2.设置函数返回值类型
n.setRetVal(Type.INT);
//3.设置参数类型
int i=0;
n.setParameter(i++, port);
//4.执行函数
n.invoke();
//5.获取函数返回值
return n.getRetVal();
}finally{
if(n!=null){
n.dispose();
}
}
}
/**
* 关闭读卡器
* @return
* @throws NativeException
* @throws IllegalAccessException
*/
public String CloseReader() throws NativeException, IllegalAccessException{
JNative n = null;
try{
//1.创建JNative对象
n = new JNative("rfid.dll","RFID_Shutdown");
//设置函数返回值类型
n.setRetVal(Type.INT);
//设置参数类型
//执行函数
n.invoke();
//获取函数返回值
return n.getRetVal();
}finally{
if(n!=null){
n.dispose();
}
}
}
public static void main(String[] args)throws NativeException, IllegalAccessException {
EcardReaderImpl impl = new EcardReaderImpl();
System.out.println("连接读卡器=="+impl.ConnectionReader(1));
System.out.println("关闭读写器=="+impl.CloseReader());
}
}

[解决办法]
堆栈溢出可能是死循环导致的
[解决办法]
楼主哪里看出来的堆栈溢出
我看着怎么像是 度地址错误~
