本文提供了一个使用 HttpClient 进行 POST 请求的 Java 示例代码。通过创建 DefaultHttpClient 和 HttpPost 对象，并设置 ContentProducer 来发送请求。此外，还展示了如何处理响应。

HttpClient方法：

private static void httpClientPost() {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(TEST_URL);

    try {
        ContentProducer cp = new ContentProducer() {
            public void writeTo(OutputStream outstream) throws IOException {
                Writer writer = new OutputStreamWriter(outstream, "UTF-8");
                writer.write("");
                writer.flush();
            }
        };

        post.setEntity(new EntityTemplate(cp));
        HttpResponse response = client.execute(post);

        System.out.println(EntityUtils.toString(response.getEntity()));
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
