問題描述

我打算做一個 java onvif 應用程序.我創建了一個新項目并從 devicemgmt.wsdl 生成了源代碼.還從 remote discovery.wsdl 生成了類.如何使用這些生成的類發現網絡中的設備?感謝您的幫助.

I am planning to do a java onvif application. I have created a new project and generated sources from devicemgmt.wsdl.Also generated the classes from remote discovery.wsdl. How can I discover a device in a network using theses generated classes? Thanks for any help.

推薦答案

devicemgmt.wsdl與發現過程無關，ONVIF發現過程基于http://specs.xmlsoap.org/ws/2005/04/discovery 它使用 SOAP over UDP.

devicemgmt.wsdl is not related to discovery process, the ONVIF discovery process is based on http://specs.xmlsoap.org/ws/2005/04/discovery it use SOAP over UDP.

如果你使用的是apache-cxf，這可以使用

If you are using apache-cxf, this can be achieve using

org.apache.cxf.ws.discovery.WSDiscoveryClient

org.apache.cxf.ws.discovery.WSDiscoveryClient

一個簡單的示例代碼可以是:

A simple sample code could be :

import java.util.List;
import javax.xml.ws.EndpointReference;
import org.apache.cxf.ws.discovery.WSDiscoveryClient;

public class Main 
{
    public static void main(String[] args) 
    {
        WSDiscoveryClient client = new WSDiscoveryClient();
        client.setVersion10(); // use WS-discovery 1.0
        client.setDefaultProbeTimeout(1000); // timeout 1s

        System.out.println("Probe:" + client.getAddress());
        List<EndpointReference> references = client.probe();

        System.out.println("Nb answsers:" + references.size());
        for (EndpointReference ref : references)
        {
            System.out.println(ref.toString());
        }
    }
}
