WebService学习笔记-使用CXF发布Webservice
WeB项目结构如图
User.java实体类
public class User { private String username; private String description; //... }
HelloWorld.java接口
@WebService public interface HelloWorld { String sayHi(@WebParam(name="text")String text); String sayHiToUser(User user); String[] SayHiToUserList(List<User> userList); }
HelloWorldImpl.java实现HelloWorld接口
@WebService(endpointInterface = "com.demo.HelloWorld", serviceName = "HelloWorld") public class HelloWorldImpl implements HelloWorld { Map<Integer, User> users = new LinkedHashMap<Integer, User>(); @Override public String sayHi(String text) { return "Hello " + text; } @Override public String sayHiToUser(User user) { users.put(users.size() + 1, user); return "Hello " + user.getUsername(); } @Override public 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服务端
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客户端
public class HelloWorldClient { //需要先启动com.demo.webServiceApp public 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); } }
启动服务端程序后,即可在客户端中调用发布的服务。
可以在浏览器中通过 http://localhost:8080/helloWorld?wsdl 来查看发布的服务
将服务集成到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.xsd http://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>
将项目部署在Tomcat上并启动,可以通过http://192.168.13.232:8080/ws_cxf/webservice/helloWorld?wsdl 来查看
此时客户端代码如下
public class NewHelloWorldClient { //需要先将项目运行在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 工具来根据url生成客户端代码
apache-cxf-3.0.1\bin wadl2java http://192.168.13.232:8080/ws_cxf/webservice/helloWorld?wsdl
参考 http://www.cnblogs.com/frankliiu-java/articles/1641949.html
出现ClassNotFound的异常时可以到 findjar.com 搜索
