1. 一个接口

package org.demo.ws;

import javax.jws.WebService;

@WebService
public interface HelloWorld
{
    String sayHi(String text);
}

2. 一个实现类

package org.demo.ws.server;

import javax.jws.WebService;
import org.demo.ws.HelloWorld;

@WebService(serviceName="hello", endpointInterface="org.demo.ws.HelloWorld")
public class HelloWorldImpl implements HelloWorld
{
    
    public HelloWorldImpl()
    {
        System.out.println("-- init HelloWorldImpl --");
    }
    
    public String sayHi(String text)
    {
        System.out.println("in sayHi, text : " + text);
        return "hi " + text + ".";
    }
}

3. 一个服务端用户名密码回调类

package org.demo.ws.server;

import java.io.IOException;
import javax.security.auth.callback.Callback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.UnsupportedCallbackException;
import javax.servlet.http.HttpServletRequest;
import javax.xml.stream.XMLStreamReader;

import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.transport.http.AbstractHTTPDestination;
import org.apache.ws.security.WSPasswordCallback;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

public class MyPasswordCallback implements CallbackHandler
{
    
    @Override
    public void handle(Callback[] callbacks) throws IOException,
            UnsupportedCallbackException
    {
        WSPasswordCallback pwCallback = (WSPasswordCallback)callbacks[0];
        String userName = pwCallback.getIdentifier();
        
        // 1. get client ip
        SoapMessage msg = (SoapMessage)pwCallback.getRequestData().getMsgContext();
        HttpServletRequest req = (HttpServletRequest)msg.getContextualProperty(AbstractHTTPDestination.HTTP_REQUEST);
        String clientIp = req.getRemoteAddr();
        
        // 2. get method name
        XMLStreamReader xmlReader = msg.getContent(XMLStreamReader.class);
        String methodName = xmlReader.getLocalName();
        
        // 3. get header
        Header header = msg.getHeaders().get(0);
        Element securityElement = (Element)header.getObject();
        String password = getFirstElementValue(securityElement, "Password");
        String nonce = getFirstElementValue(securityElement, "Nonce");
        String time = getFirstElementValue(securityElement, "Created");
        
        // 4. log
        System.out.println("clientIp=" + clientIp + ", methodName=" + methodName 
                + ", userName=" + userName + ", password=" + password + ", nonce=" + nonce + ", time=" + time);
        
        if ("user1".equals(userName))
        {
            pwCallback.setPassword("password1");
        }
    }
    
    /**
     * 根据tagName获取第一个匹配的XML元素内容
     * @param current
     * @param tagName
     * @return
     */
    private String getFirstElementValue(Element current, String tagName)
    {
        String result = null;
        Element tmpElement = null;
        Element firstElement = null;
        
        NodeList nodeList = current.getChildNodes();
        for (int i = 0; i < nodeList.getLength(); i++) {
            Node node = nodeList.item(i);
            if (!(node instanceof Element)) {
                continue;
            }
            
            tmpElement = (Element)node;
            if (tmpElement.getLocalName().equals(tagName)) {
                result = tmpElement.getTextContent();
                break;
            }
            if (firstElement == null) {
                firstElement = tmpElement;
            }
        }
        
        if (result == null && firstElement != null) {
            result = getFirstElementValue(firstElement, tagName);
        }
        return result;
    }
}
