XFire框架实现WebService(二)
有了XFire框架实现WebService(一),就可以继续开发WebService的简单应用。
Webservice的服务端(WEB工程):
两个java bean类:
Course.java
package cn.com.bean;
public class Course {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
User.java
package cn.com.bean;
public class User {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
一个Service接口入口: IHelloService.java
package cn.com.service;
import java.util.List;
import cn.com.bean.Course;
import cn.com.bean.User;
public interface IHelloService {
public String sayHello(String t);
public Course choose(User u);
public List test(List t);
}
接口的实现类: HelloServiceImpl.java
package cn.com.service;
import java.util.ArrayList;
import java.util.List;
import cn.com.bean.Course;
import cn.com.bean.User;
public class HelloServviceImpl implements IHelloService {
public Course choose(User u){
System.out.println(u.getName());
Course c = new Course();
c.setName("Computer");
return c;
}
public String sayHello(String t) {
return "Hello,"+t;
}
public List test(List t) {
for(int i=0;i<t.size();i++){
System.out.println((String)t.get(i));
}
List list = new ArrayList();
Course c = new Course();
c.setName("English Reading");
list.add(c);
return list;
}
}
WebSevice定义描述文件: services.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
<name>HelloService</name>
<namespace>my/HelloService</namespace>
<serviceClass>cn.com.service.IHelloService</serviceClass>
<implementationClass>cn.com.service.HelloServviceImpl</implementationClass>
</service>
</beans>
因为我们用到了List等集合类型,所以需要定义Mapping关系,文件名为:IHelloService.aegis.xml
<?xml version="1.0" encoding="UTF-8"?>
<mappings>
<mapping>
<method name="test">
<parameter index="0" componentType="java.lang.String" />
<return-type componentType="cn.com.bean.Course"/>
</method>
</mapping>
</mappings>
最后Web.xml文件添加XFire需要用到的Servlet:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>XFireServlet</servlet-name>
<servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>XFireServlet</servlet-name>
<url-pattern>/servlet/XFireServlet/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>XFireServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
客户端代码(一个java工程即可):
package test;
import java.net.MalformedURLException;
import java.util.ArrayList;
import java.util.List;
import org.codehaus.xfire.XFireFactory;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import cn.com.bean.Course;
import cn.com.bean.User;
import cn.com.service.IHelloService;
public class ClientTest {
public static void main(String[] args) throws MalformedURLException {
//Service:是一个服务端点,它的工作是处理XML消息
Service srvcModel = new ObjectServiceFactory().create(IHelloService.class);
/*XFireProxyFactory:
* 该工厂用来创建XFire SOAP客户端的远程对象,返回的实例将调用
* 远程对象的所有方法
*/
XFireProxyFactory factory = new XFireProxyFactory(XFireFactory.newInstance().getXFire());
String helloWorldURL = "http://localhost:8088/testWebService2/services/HelloService";
IHelloService service = (IHelloService)factory.create(srvcModel,helloWorldURL);
System.out.println(service.sayHello("Robin"));
User u = new User();
u.setName("RRRRR");
Course c = service.choose(u);
System.out.println(c.getName());
List list = new ArrayList();
list.add("test1");
list.add("test2");
List tempList = service.test(list);
for(int i=0;i<tempList.size();i++){
Course course = (Course)tempList.get(i);
System.out.println(course.getName());
}
}
}
