WeB項目結構

User.java實體類

public class User {private String username;private String description;//...}

HelloWorld.java介面

@WebServicepublic interface HelloWorld {String sayHi(@WebParam(name="text")String text);    String sayHiToUser(User user);    String[] SayHiToUserList(List<User> userList);}

HelloWorldImpl.java實現HelloWorld介面

@WebService(endpointInterface = "com.demo.HelloWorld", serviceName = "HelloWorld")public class HelloWorldImpl implements HelloWorld {Map<Integer, User> users = new LinkedHashMap<Integer, User>();@Overridepublic String sayHi(String text) {return "Hello " + text;}@Overridepublic String sayHiToUser(User user) {users.put(users.size() + 1, user);return "Hello " + user.getUsername();}@Overridepublic String[] SayHiToUserList(List<User> userList) {String[] result = new String[userList.size()];        int i=0;        for(User u:userList){             result[i] = "Hello " + u.getUsername();             i++;        }        return result;}}

webServiceApp.java服務端

public class webServiceApp {public static void main(String[] args) { System.out.println("Starting web service... ");         HelloWorldImpl implementor= new HelloWorldImpl();         String address="http://localhost:8080/helloWorld";         Endpoint.publish(address, implementor);         System.out.println("Web service started");}}

HelloWorldClient.java用戶端

public class HelloWorldClient {//需要先啟動com.demo.webServiceApppublic static void main(String[] args) {JaxWsProxyFactoryBean svr = new JaxWsProxyFactoryBean();        svr.setServiceClass(HelloWorld.class);        svr.setAddress("http://localhost:8080/helloWorld");        HelloWorld hw = (HelloWorld) svr.create();        User user = new User();        user.setUsername("Umgsai");        user.setDescription("test");        System.out.println(hw.sayHiToUser(user));        String sayHi = hw.sayHi("test~~~");        System.out.println(sayHi);}}

啟動服務端程式後，即可在用戶端中調用發布的服務。

可以在瀏覽器中通過 http://localhost:8080/helloWorld?wsdl 來查看發布的服務

將服務整合到Spring中

applicationContext.xml

<?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:jaxws="http://cxf.apache.org/jaxws"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"><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="helloWorld" implementor="com.demo.HelloWorldImpl"address="/helloWorld" /><bean id="client" class="com.demo.HelloWorld" factory-bean="clientFactory"factory-method="create" /><bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"><property name="serviceClass" value="com.demo.HelloWorld" /><property name="address"value="http://localhost:8080/ws_cxf/webservice/helloWorld" /></bean></beans>

web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">  <display-name>ws_cxf</display-name>  <welcome-file-list>    <welcome-file>default.jsp</welcome-file>  </welcome-file-list>  <context-param><param-name>contextConfigLocation</param-name><param-value>WEB-INF/classes/applicationContext.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><servlet><servlet-name>CXFServlet</servlet-name><display-name>CXFServlet</display-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>/webservice/*</url-pattern></servlet-mapping></web-app>

將項目部署在Tomcat上並啟動，可以通過http://192.168.13.232:8080/ws_cxf/webservice/helloWorld?wsdl 來查看

此時用戶端代碼如下

public class NewHelloWorldClient {//需要先將項目運行在Tomcat上public static void main(String[] args) {ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");HelloWorld client = (HelloWorld) applicationContext.getBean("client");User user1 = new User();        user1.setUsername("Tony");        user1.setDescription("test");        User user2 = new User();        user2.setUsername("freeman");        user2.setDescription("test");        List<User> userList= new ArrayList<User>();        userList.add(user1);        userList.add(user2);        String[] sayHiToUserList = client.SayHiToUserList(userList);        System.out.println(sayHiToUserList[0]);}}

可以使用CXF的wadl2java 工具來根據url產生用戶端代碼

apache-cxf-3.0.1\bin wadl2java 650) this.width=650;" src="/e/u261/themes/default/images/spacer.gif" style="background:url("/e/u261/lang/zh-cn/images/localimage.png") no-repeat center;border:1px solid #ddd;" alt="spacer.gif" />http://192.168.13.232:8080/ws_cxf/webservice/helloWorld?wsdl

出現ClassNotFound的異常時可以到 findjar.com 搜尋
