java的http接口传输对象

java的http接口传输对象

解决方法：

对象要实现Serializable接口。

1.服务端

JasperPrint jasperPrint = null;//你的对象

response.setContentType("application/json; charset=UTF-8");

ObjectOutputStream out = new ObjectOutputStream(response.getOutputStream());

out.writeObject(jasperPrint);

out.close();

2.客户端

          URL urlObj = new URL(url);

          HttpURLConnection conn = (HttpURLConnection) urlObj.openConnection();

          // 连接超时

           conn.setDoInput(true);

           conn.setDoOutput(true);

           conn.setConnectTimeout(25000);

           // 读取超时 --服务器响应比较慢,增大时间

           conn.setReadTimeout(25000);

           conn.setRequestMethod("POST");

           conn.connect();

           ObjectInputStream objectInputStream = new ObjectInputStream((InputStream) conn.getContent());

           JasperPrint jasperPrint = (JasperPrint) objectInputStream.readObject();

           // 断开连接

           conn.disconnect();
