如何使用 Apache HttpClient 将序列化对象发送到 servlet [英] How to send serialized object to a servlet using Apache HttpClient

问题描述

我有一个 Main() 类，我在其中序列化了一个名为 Names 的类的对象.我正在使用 Apache HttpClient 的 HttpPost() 来调用 servlet.

I have a Main() class where I serialize an object of a class called Names. I am using Apache HttpClient's HttpPost() to call a servlet.

public static void main(String[] args) {

    Names names = new Names();
    names.setName("ABC");
    names.setPlace("Bangalore");
    ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("Name.txt"));
    out.writeObject(names);
    out.close();

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://localhost:6080/HttpClientGson/FirstHttpPostServlet");

现在，我如何发送 ObjectOutputStream 对象?我写了以下行httppost.setEntity(out)

Now, how do I send the ObjectOutputStream object? I wrote the following line httppost.setEntity(out)

但是 setEntity() 只能接受 HttpEntity 类型的对象.是否还有其他 HttpClient 方法可用于发送序列化对象?

But setEntity() can only take objects of HttpEntity type. Is there any other method of HttpClient that I can use to send serialized object?

推荐答案

您可以 SerializableEntity 类随 HttpClient 一起提供

You could SerializableEntity class shipped with HttpClient

httpost.setEntity(new SerializableEntity(mySerializableObj, false));

但是请注意，只有在绝对需要时才应使用二进制对象序列化.通常应首选其他序列化格式，例如 XML 或 JSON.

Please note, though, that binary object serialization should be used only when absolutely required. Other serialization formats such as XML or JSON should generally be preferred.
