我用来将我的 reg_be obj 转换为输入流的代码。
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject(reg_be);
oos.flush();
oos.close();
InputStream is = new ByteArrayInputStream(baos.toByteArray());
然后我将此输入流传递给 web 服务。我的网络服务代码是
public String getText(@Context HttpServletRequest request) throws IOException {
//
Registration_BE reg_be=new Registration_BE();
InputStream in=request.getInputStream();
ObjectInputStream ois = new ObjectInputStream(in);
try {
reg_be=(Registration_BE) ois.readObject();
} catch (ClassNotFoundException ex) {
Logger.getLogger(CustomerregistrationResource.class.getName()).log(Level.SEVERE, null, ex);
}
}
在 Web 服务中，输入流没有正确接收，为什么？这种方法适用于我的图像输入流。但是对于这个对象它不起作用，为什么？请帮助我..
我收到此错误：
