一、CXF的介绍
Apache CXF是一个开源的WebService框架,CXF大大简化了Webservice的创建,同时它继承了XFire的传统,一样可以和spring天然的进行无缝的集成。CXF框架是一种基于servlet技术的SOA应用开发框架,要正常运用基于CXF应用框架开发的企业应用,除了CXF应用本身之外,还需要JDK和servlet容器的支持。
二、CXF的准备条件
所需要的jar包:
xmlbeans-2.4.0.jar
wss4j-1.5.9.jar
jetty-server-7.1.6.v20100715.jar
jetty-util-7.1.6.v20100715.jar
geronimo-ws-metadata_2.0_spec-1.1.3.jar
geronimo-activation_1.1_spec-1.1.jar
geronimo-servlet_3.0_spec-1.0.jar
velocity-1.6.4.jar
jaxb-xjc-2.2.1.1.jar
xml-resolver-1.2.jar
wsdl4j-1.6.2.jar
cxf-2.3.0.jar
XmlSchema-1.4.7.jar
jaxb-api-2.2.1.jar
jaxb-impl-2.2.1.1.jar
neethi-2.0.4.jar
geronimo-annotation_1.0_spec-1.1.1.jar
geronimo-stax-api_1.0_spec-1.0.1.jar

三、创建webservice服务端
1、先将jar包放入lib目录
2、在web.xml中配置CXF框架的核心servlet
- <!-- CXF -->
- <servlet>
- <servlet-name>CXFServlet</servlet-name>
- <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
- <load-on-startup>1</load-on-startup>
- </servlet>
- <servlet-mapping>
- <servlet-name>CXFServlet</servlet-name>
- <url-pattern>/services/*</url-pattern>
- </servlet-mapping>
3、在applicationContext.xml中导入xml,并且发布webservice服务。
- <?xml version="1.0" encoding="UTF-8"?>
- <beans
- xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xmlns:p="http://www.springframework.org/schema/p"
- xmlns:tx="http://www.springframework.org/schema/tx"
- xmlns:aop="http://www.springframework.org/schema/aop"
- xmlns:jaxws="http://cxf.apache.org/jaxws"
- xmlns:jaxrs="http://cxf.apache.org/jaxrs"
- xsi:schemaLocation="http://www.springframework.org/schema/beans
- http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
- http://www.springframework.org/schema/tx
- http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
- http://www.springframework.org/schema/aop
- http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
- http://cxf.apache.org/jaxws
- http://cxf.apache.org/schemas/jaxws.xsd
- http://cxf.apache.org/jaxrs
- http://cxf.apache.org/schemas/jaxrs.xsd
- "
- default-autowire="byName"
- >
- <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" />
- <!-- <jaxws:endpoint id="facelookWebService" address="/facelookWebService" implementor="com.facelook.webservice.server.FacelookWebServiceImpl"></jaxws:endpoint> -->
- <!-- 不知道为什么,这里的webservice配置,只能用bean来实现,否则 注入的service为空。但是之前有个项目却可以,百思不得其解。。 -->
- <bean id="facelookWebService" class="com.facelook.webservice.server.FacelookWebServiceImpl"/>
- <jaxws:endpoint id="facelookWebService1" address="/facelookWebService" implementorClass="com.facelook.webservice.server.FacelookWebServiceImpl">
- <jaxws:implementor ref="facelookWebService"/>
- </jaxws:endpoint>
- </beans>
4、定义webservice接口FacelookWebService 和 实现类FacelookWebServiceImpl。
- @WebService
- public interface FacelookWebService {
- /**
- * 根据传递的条件获取相册信息
- * xml的格式规范
- * <?xml version=\"1.0\" encoding=\"UTF-8\"?>
- * <facelook>
- * <condition>
- * <name></name>
- * <description></description>
- * <pageno></pageno>
- * <pagesize></pagesize>
- * </condition>
- * </facelook>
- * 这里的WebParam必须指定,否则调用的时候返回null
- * @return
- */
- public String getAlbumList(@WebParam(name="xmlStr") String xmlStr);
- }
- @WebService
- //这后面的可以不写注释后面的配置,在applicationContext配置也一样(serviceName="facelookWebService",endpointInterface="com.facelook.webservice.server.FacelookWebService")
- public class FacelookWebServiceImpl implements FacelookWebService{
- @Autowired
- private AlbumService albumService;
- @Override
- public String getAlbumList(String xmlStr) {
- try {
- List<Album> albumList = getAlbumPage(xmlStr);
- JSONArray jsonArray = JSONArray.fromObject(albumList);
- return jsonArray.toString();
- } catch (Exception e) {
- e.printStackTrace();
- }
- return null;
- }
- }
这样子,基本上就可以了。
5、保存代码,发布项目,启动tomact。
在地址栏输入:http://localhost:8080/house/services/houseWebService?wsdl 即可看到发布的服务端的明细。
显示如下:
这就表示CXF发布的webservice服务端成功了。
6、通过客户端调用服务端webservice。
axis的客户端访问:
- public static void main(String[] args) throws ServiceException, RemoteException, MalformedURLException {
- String xmlStr = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
- + " <facelook>"
- + " <condition>"
- + " <name>家</name>"
- + " <description></description>"
- + " <pageno></pageno>"
- + " <pagesize></pagesize>"
- + " </condition>"
- + " </facelook>";
- Service service = new Service();
- Call call = (Call) service.createCall();
- call.setTargetEndpointAddress("http://localhost:8080/facelook/services/facelookWebService?wsdl");
- QName qName = new QName("http://server.webservice.facelook.com/", "getAlbumList");
- call.setOperationName(qName);
- call.setUseSOAPAction(true);
- //这下面两行一定要加上,否则接收在服务器端收不到。
- call.addParameter("xmlStr", XMLType.XSD_STRING, ParameterMode.IN);
- call.setReturnType(XMLType.XSD_STRING);
- String result = (String) call.invoke(new Object[] { xmlStr });
- System.out.println(result);
- //将返回的字符串转换成list集合
- //JSONArray array = JSONArray.fromObject(result);
- //List<Album> list = JSONArray.toList(array,Album.class);
- }
CXF客户端访问:
- public static void main(String[] args) throws Exception {
- //这个是用cxf 客户端访问cxf部署的webservice服务
- //千万记住,访问cxf的webservice必须加上namespace ,否则通不过
- //现在又另外一个问题,传递过去的参数服务端接收不到
- JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
- org.apache.cxf.endpoint.Client client = dcf.createClient("http://localhost:8080/facelook/services/facelookWebService?wsdl");
- //url为调用webService的wsdl地址
- QName name=new QName("http://server.webservice.facelook.com/","getAlbumList");
- //namespace是命名空间,methodName是方法名
- String xmlStr = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
- + " <facelook>"
- + " <condition>"
- + " <name>家</name>"
- + " <description></description>"
- + " <pageno></pageno>"
- + " <pagesize></pagesize>"
- + " </condition>"
- + " </facelook>";
- //paramvalue为参数值
- Object[] objects=client.invoke(name,xmlStr);
- //调用web Service//输出调用结果
- System.out.println(objects[0].toString());
- }
在这里面传递的xml规范由 服务端自己规范好了,然后去解析、获取参数,执行相应的操作,返回想要的结果给调用的客户端。。
