Question

我正在开发一个需要通过CXF Web服务连接到远程数据库的Android应用程序。我尝试过使用Soap，但是由于各种问题留下了选项，并采用了基于REST的轻量级服务（通过添加对现有cxf Web服务的注释。）我有一个从活动内部调用的Rest客户端。我使用简单的参数，如String，int等。现在我想传递一个用户定义的对象到服务并从服务器端获取一些String值。我该怎么做？请帮助...在谷歌搜索我发现有关使用JSON，JAXB等的文章，但我不知道这些做什么或如何使用这些。我对使用这些技术编程非常陌生。

您可以为客户端代码执行类似的操作：

private static final String URI = "http://localhost/rest/customer";

private Customer readCustomer(String id) {
    try {
        URL url = new URL(URI + "/" + id);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        connection.setRequestProperty("Accept", "application/xml");

        InputStream data = connection.getInputStream();
        // TODO - Read data from InputStream

        connection.disconnect();
        return customer;
    } catch(Exception e) {
        throw new RuntimeException(e);
    }
}

private void createCustomer(Customer customer) {
    try { 
        URL url = new URL(URI);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setInstanceFollowRedirects(false);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type", "application/xml");

        OutputStream os = connection.getOutputStream();
        // TODO - Write data to OutputStream
        os.flush();

        connection.getResponseCode();
        connection.disconnect();
    } catch(Exception e) {
        throw new RuntimeException(e);
    }
}

private void updateCustomer(Customer customer) {
    try {
        URL url = new URL(URI);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setInstanceFollowRedirects(false);
        connection.setRequestMethod("PUT");
        connection.setRequestProperty("Content-Type", "application/xml");

        OutputStream os = connection.getOutputStream();
        // TODO - Write data to OutputStream
        os.flush();

        connection.getResponseCode();
        connection.disconnect();
    } catch(Exception e) {
        throw new RuntimeException(e);
    }
}

private void deleteCustomer(String id) {
    try {
        URL url = new URL(URI + "/" + id);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("DELETE");
        connection.getResponseCode();
        connection.disconnect();
    } catch(Exception e) {
        throw new RuntimeException(e);
    }
}

如何使用CXF REST客户端传递用户定义的对象？
