WebService學習筆記-使用CXF釋出Webservice

WeB項目結構如圖

User.java實體類

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實作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.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);
	}
}      

啟動服務端程式後，即可在用戶端中調用釋出的服務。

可以在浏覽器中通過 http://localhost:8080/helloWorld?wsdl 來檢視釋出的服務

将服務內建到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"

	<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">

	<listener>

	</servlet>

 	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/webservice/*</url-pattern>
	</servlet-mapping>
</web-app>      

将項目部署在Tomcat上并啟動，可以通過http://192.168.13.232:8080/ws_cxf/webservice/helloWorld?wsdl 來檢視

此時用戶端代碼如下

public class NewHelloWorldClient {
	//需要先将項目運作在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生成用戶端代碼

apache-cxf-3.0.1\bin wadl2java http://192.168.13.232:8080/ws_cxf/webservice/helloWorld?wsdl
