JDK6开发WebService及用户认证

一、编写服务端并发布
1、定义接口

public interface EchoService {

	 public String echo(String name);
	
}

2、接口实现

@WebService(name="wsecho",portName="echoServicePort", serviceName="echoService",targetNamespace="http://ws.logcd.net/") 
@SOAPBinding(style = Style.DOCUMENT,use = Use.LITERAL)//Style.DOCUMENT为默认值
@HandlerChain(file="handle-chain.xml")
public class EchoServiceImpl implements EchoService{

	@WebMethod()
	public String echo(//指定参数名及命名空间
			@WebParam(name="userName", targetNamespace="http://ws.logcd.net/") String name) {
		return "hello, " + name;
	}

}

3、处理用户身份认证类

public class AuthValidatorHandler implements SOAPHandler<SOAPMessageContext> {

	public static final String TARGET_NAMESPACE = "http://ws.logcd.net/";
	
	public static final String AUTH_HEADER_NAME = "AuthHeader";
	
	public static final Map<String,String> cacheAcountMap = new HashMap<String,String>();
	
	static{
		cacheAcountMap.put("510028", "123456");
	}
	
	@SuppressWarnings("unchecked")
	public boolean handleMessage(SOAPMessageContext ctx) {
    	
       Boolean isResponsed=(Boolean)ctx.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
       if(!isResponsed){
           SOAPMessage msg=ctx.getMessage();
           try {
        	  
        	   String id = "", pwd = "";
        	   SOAPHeader header = msg.getSOAPHeader();
              Iterator<SOAPHeaderElement> it = header.getChildElements(new QName(TARGET_NAMESPACE, AUTH_HEADER_NAME));
              
              if(it.hasNext()){
            	  SOAPHeaderElement headElem = (SOAPHeaderElement)it.next();
            	  Iterator<SOAPElement> eleIt = headElem.getChildElements();
            	  
            	  while(eleIt.hasNext()){
            		  SOAPElement ele = eleIt.next();
            		  String key = ele.getLocalName();
            		  
            		  if(key.toUpperCase().equals("ACCOUNT")){
            			  String val = ele.getValue();
            			  String[] arr = val.split("/");
            			  if(arr.length == 2){
	            			  id = arr[0]; 
	            			  pwd = arr[1];
            			  }
            			  break;
            		  }
            	  }
              }
              System.out.println("id="+id+",pwd="+pwd);
              if(StringUtils.isEmpty(id) || StringUtils.isEmpty(pwd)){
            	 throw new SOAPFaultException(new QName(TARGET_NAMESPACE, "-1"),
            			 "User Acount Err!", "id or pwd is empty.", null);
              }
              
              return authValidate(id, pwd);
           } catch (SOAPException e) {
              throw new RuntimeException(e);
           }
       }
       return false;
    }
    
    /*
     * 验证用户名和密码
     */
    private boolean authValidate(String id, String pwd){
    	if(cacheAcountMap.containsKey(id) 
    				&& ((String)cacheAcountMap.get(id)).equals(pwd)){
    		return true;
    	}else{
       	 	throw new SOAPFaultException(new QName(TARGET_NAMESPACE, "-2"),
    			 "Unauthorized Visit!", "id or pwd incorrect.", null);
    	}
    }
   
	@Override
	public void close(MessageContext arg0) {
		
	}

	@Override
	public boolean handleFault(SOAPMessageContext arg0) {
		return false;
	}

	@Override
	public Set<QName> getHeaders() {
		return null;
	}
}

4、请求处理链（handle-chain.xml）

<?xml version="1.0" encoding="UTF-8"?>
<javaee:handler-chains xmlns:javaee="http://java.sun.com/xml/ns/javaee"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    
    <javaee:handler-chain>
    
       <javaee:handler>
       
           <javaee:handler-class>com.cdmcs.jws.auth.AuthValidatorHandler</javaee:handler-class>
           
       </javaee:handler>
       
    </javaee:handler-chain>
    
</javaee:handler-chains>

5、发布WS服务

public class WSPublisher {

	public static void main(String[] args){
		
		Endpoint.publish("http://localhost:8099/echoService", new EchoServiceImpl()); 	
		System.out.println("publish all services...");
		
	}
	
}

二、编写调用WS的客户端

public class Jdk6WsAxisClient {

	public static void main(String[] args) {  
        try {  
            String endpoint = "http://localhost:8099/echoService";  
            String nameSpace = "http://ws.logcd.net/";   
  
			Service service = new Service();           
            Call call = (Call) service.createCall();  
            call.setTargetEndpointAddress(endpoint);  
            call.setOperationName(new QName(nameSpace, "echo"));  
  
            //参数名为WebParam中指定的参数名，未指定参数名时传arg0-argN
            //call.addParameter("userName", XMLType.XSD_STRING, ParameterMode.IN); //Style.DOCUMENT，且方法参数没有指定命名空间或Style.RPC 
            call.addParameter(new QName(nameSpace, "userName"), XMLType.XSD_STRING, ParameterMode.IN);//Style.DOCUMENT指定了命名空间
            
            call.setUseSOAPAction(true);  
            call.setReturnType(org.apache.axis.Constants.XSD_STRING);  
            call.setSOAPActionURI(nameSpace+"echoService"); 
            
            SOAPHeaderElement soapHeaderElement = new SOAPHeaderElement(nameSpace, "AuthHeader"); 
            soapHeaderElement.addChildElement("ACCOUNT").setValue("510028/123456");    
            call.addHeader(soapHeaderElement);
            
            String result = (String) call.invoke(new Object[] {"frank"});  
              
            System.out.println(result);  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }  	
	
}
