*****cxf之Filter问题*****
说明：过滤器使用范围还是挺广泛的，比如webservice中的安全认证、数字签名、Token认证都可以使用过滤器来做；下面纯粹是一个小例子，以方便后期使用时查询，仅供参考。以服务端和客户端两部分介绍(所需要包自己导入)：
【服务端】
一、定义接口
import javax.jws.WebService;
@WebService
public interface HelloWorld {
public String sayHello(String inputXML);
}
二、定义实现类
@WebService(endpointInterface = "com.dyc.dao.HelloWorld")
public class HelloWorldImpl implements HelloWorld {
@WebMethod
public String sayHello(@WebParam(name = "inputXML") String inputXML) {
// TODO Auto-generated method stub
String name = ParseXml.parseElement(inputXML, "name");
System.out.println("Server接收到输入参数为-->" + name);
return "How are you ?-->" + name;
}
}
三、XML解析类（dom4j，请自导入包）
public class ParseXml {
public static String parseElement(String inputXML, String objStr) {
InputStream in = null;
String str = null;
Element rootElement = null;
try {
in = new ByteArrayInputStream(inputXML.getBytes("UTF-8"));
SAXReader reader = new SAXReader();
Document document = reader.read(in); // 把流转成document对象。
rootElement = document.getRootElement();
Element tokenNode = rootElement.element(objStr);
if (tokenNode != null) {
str = tokenNode.getTextTrim();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (DocumentException e) {
e.printStackTrace();
}
return str;
}
}
四、过滤器
public class TokenInFilter extends AbstractPhaseInterceptor<SoapMessage> {
public TokenInFilter(String phase) {
super(Phase.PRE_INVOKE);
}
public void handleMessage(SoapMessage message) throws Fault {
// 获取SOAP消息的全部头
List<Header> headers = message.getHeaders();
if (null == headers || headers.size() < 1) {
throw new Fault(new SOAPException("SOAP消息头格式不对哦！"));
}
try{
for (Header header : headers) {
SoapHeader soapHeader = (SoapHeader) header;
// 取出SOAP的Header元素
/*解析soap的头信息*/
Element element = (Element) soapHeader.getObject();
XMLUtils.printDOM(element);
NodeList tokenList = element
.getElementsByTagName("tns:token");
/*NodeList nameList = element
.getElementsByTagName("tns:name");
NodeList passList = element
.getElementsByTagName("tns:pass");*/
String token = tokenList.item(0).getTextContent();
System.out.println("Token------>"+token);
//在此验证Token的合法性
/* System.out.println(nameList.item(0).getTextContent());
System.out.println(passList.item(0).getTextContent());*/
}
}catch(Exception e){
throw new Fault(new SOAPException("解析Soap信息出错！"));
}
}
}
五、XML配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/beans_*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<display-name>cxf</display-name>
<servlet>
<servlet-name>cxf</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>cxf</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>60</session-timeout>
</session-config>
</web-app>
六、bean_1.xml:用来发布服务的配置
<import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <!-- 自定义拦截器 --> <bean id="authIntercetpr" class="com.dyc.filter.TokenInFilter"> <constructor-arg value="receive" /> </bean> <jaxws:endpoint id="helloWorld" implementor="com.dyc.impl.HelloWorldImpl" address="/HelloWorld"> <jaxws:inInterceptors> <!-- 进入webservice之前的拦截器 --> <ref bean="authIntercetpr" /> </jaxws:inInterceptors> </jaxws:endpoint>
【客户端】
一、利用wsdl2java生成客户端代码(省略，代码太多了)
例：wsdl2java -p com.dyc.client -d d:/ws -verbose http://localhost:6888/webgisplatform/BaseService?wsdl
二、将生成的代码导入一个工程，可以建任意一个java工程
三、生成AddSoapHeader，模拟生成一个soap的头信息
public class AddSoapHeader extends AbstractSoapInterceptor {
private static String nameURI="http://localhost:8080/cxf_filter/HelloWorld";
public AddSoapHeader(){
super(Phase.WRITE);
}
public void handleMessage(SoapMessage message) throws Fault {
String token="12345678956789123344444";
QName qname=new QName("RequestSOAPHeader");
Document doc=DOMUtils.createDocument();
//自定义节点
Element spId=doc.createElement("tns:token");
spId.setTextContent(token);
Element username=doc.createElement("tns:name");
username.setTextContent("gary");
Element password=doc.createElement("tns:pass");
password.setTextContent("123456");
Element root=doc.createElementNS(nameURI, "tns:RequestSOAPHeader");
root.appendChild(spId);
root.appendChild(username);
root.appendChild(password);
SoapHeader head=new SoapHeader(qname,root);
List<Header> headers=message.getHeaders();
headers.add(head);
System.out.println(">>>>>添加header<<<<<<<");
}
}
四、写一个调试入口main方法
public void testSend() {
try {
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
List<Interceptor<? extends Message>> list = new ArrayList<Interceptor<? extends Message>>();
// 添加soap header
list.add(new AddSoapHeader());
// 添加soap消息日志打印
list.add(new org.apache.cxf.interceptor.LoggingOutInterceptor());
factory.setOutInterceptors(list);
factory.setServiceClass(HelloWorld.class);
factory
.setAddress("http://localhost:8080/cxf_filter/HelloWorld");
Object obj = factory.create();
System.out.println(obj == null ? "NULL" : obj.getClass().getName());
if (obj != null) {
HelloWorld ws = (HelloWorld) obj;
String name = Dom4jDemo.createDocument("");
System.out.println(name);
// 1、获取连接
String str = ws.sayHello(name) ;
System.out.println("res--->" + str);
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
public static void main(String[] args) {
Test tc = new Test();
tc.testSend();
}
OK！发布好服务端，启动服务，可以测试了！
