【WebService】通过CXF发布WebService第一例

CXF的理论知识就不重复了。

• 发布服务

1、在OSGI bundle中发布，所以首先创建OSGI工程，并加入CXF所需要的库文件，

       MANIFEST.MF文件内容：

  2、声明一个WebService服务接口并实现

        WebService接口文件 IUserManager.java

[java] view plaincopyprint?

1. package mysimplewebservicecxf01.user.api;  
2.   
3. import java.util.List;  
4.   
5. import javax.jws.WebService;  
6.   
7. import mysimplewebservicecxf01.user.api.model.User;  
8.   
9. @WebService  
10. public interface IUserManager {  
11.     int addUser(String name);  
12.     List<User> queryUsers();  
13.     User queryUser(int userId);  
14.     boolean deleteUser(int userId);  
15. }  

package mysimplewebservicecxf01.user.api;import java.util.List;import javax.jws.WebService;import mysimplewebservicecxf01.user.api.model.User;@WebServicepublic interface IUserManager {    int addUser(String name);    List<User> queryUsers();    User queryUser(int userId);    boolean deleteUser(int userId);}

     Java Bean对象User.java

[java] view plaincopyprint?

1. package mysimplewebservicecxf01.user.api.model;  
2.   
3. public class User {  
4.     public int getId() {  
5.         return id;  
6.     }  
7.     public void setId(int id) {  
8.         this.id = id;  
9.     }  
10.     public String getName() {  
11.         return name;  
12.     }  
13.     public void setName(String name) {  
14.         this.name = name;  
15.     }  
16.     private int id;  
17.     private String name;  
18. }  

package mysimplewebservicecxf01.user.api.model;public class User {public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}private int id;private String name;}

      WebService的实现 UserManager.java

[java] view plaincopyprint?

1. package mysimplewebservicecxf01.user.impl;  
2.   
3. import java.util.ArrayList;  
4. import java.util.HashMap;  
5. import java.util.List;  
6. import java.util.Map;  
7.   
8. import mysimplewebservicecxf01.user.api.IUserManager;  
9. import mysimplewebservicecxf01.user.api.model.User;  
10.   
11. public class UserManager implements IUserManager {  
12.     Map<Integer, User> userMap = new HashMap<Integer, User>();  
13.     int newID = 0;  
14.     @Override  
15.     public int addUser(String name) {  
16.           
17.         int newId = this.newID++;  
18.         System.out.println("add a user begin,userId:"+newId + ",name:"+name);  
19.         User user = new User();  
20.         user.setId(newId);  
21.         user.setName(name);  
22.         userMap.put(newId, user);  
23.         System.out.println("add a user ok");  
24.         return newId;  
25.     }  
26.   
27.     @Override  
28.     public List<User> queryUsers() {  
29.         System.out.println("query all users begin");  
30.         List<User> userList = new ArrayList<User>();  
31.         for(User user:userMap.values()){  
32.             userList.add(user);  
33.         }  
34.         System.out.println("query all users end,count:"+userList.size());  
35.         return userList;  
36.     }  
37.   
38.     @Override  
39.     public User queryUser(int userId) {  
40.         System.out.println("query a user begin, userId:"+userId);  
41.         if(userMap.containsKey(userId)){  
42.             User user = userMap.get(userId);  
43.             System.out.println("query a user begin, userId:"+userId+", name:"+user.getName());  
44.             return user;  
45.         }  
46.         System.out.println("query a user end,no the user("+userId+")");  
47.         return null;  
48.     }  
49.   
50.     @Override  
51.     public boolean deleteUser(int userId) {  
52.         System.out.println("delete a user begin, userId:"+userId);  
53.         if(userMap.containsKey(userId)){  
54.             User user = userMap.remove(userId);  
55.             System.out.println("delete a user end, userId:"+userId+", name:"+user.getName());  
56.         }  
57.         return true;  
58.     }  
59. }  

package mysimplewebservicecxf01.user.impl;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import mysimplewebservicecxf01.user.api.IUserManager;import mysimplewebservicecxf01.user.api.model.User;public class UserManager implements IUserManager {Map<Integer, User> userMap = new HashMap<Integer, User>();int newID = 0;@Overridepublic int addUser(String name) {int newId = this.newID++;System.out.println("add a user begin,userId:"+newId + ",name:"+name);User user = new User();user.setId(newId);user.setName(name);userMap.put(newId, user);System.out.println("add a user ok");return newId;}@Overridepublic List<User> queryUsers() {System.out.println("query all users begin");List<User> userList = new ArrayList<User>();for(User user:userMap.values()){userList.add(user);}System.out.println("query all users end,count:"+userList.size());return userList;}@Overridepublic User queryUser(int userId) {System.out.println("query a user begin, userId:"+userId);if(userMap.containsKey(userId)){User user = userMap.get(userId);System.out.println("query a user begin, userId:"+userId+", name:"+user.getName());return user;}System.out.println("query a user end,no the user("+userId+")");return null;}@Overridepublic boolean deleteUser(int userId) {System.out.println("delete a user begin, userId:"+userId);if(userMap.containsKey(userId)){User user = userMap.remove(userId);System.out.println("delete a user end, userId:"+userId+", name:"+user.getName());}return true;}}

3、实现一个WebService服务发布的工具类，用来发布WebService服务

[java] view plaincopyprint?

1. package mysimplewebservicecxf01.publish;  
2.   
3. import java.util.ArrayList;  
4. import java.util.List;  
5.   
6. import mysimplewebservicecxf01.service.interceptor.SampleInterceptorService;  
7.   
8. import org.apache.cxf.jaxws.JaxWsServerFactoryBean;  
9.   
10. public class ServiceManager {  
11.     private static final ServiceManager instance = new ServiceManager();  
12.     List<String> serviceList = new ArrayList<String>();  
13.       
14.     public static ServiceManager getInstance(){  
15.         return instance;  
16.     }  
17.       
18.     private ServiceManager(){  
19.           
20.     }  
21.       
22.     public void publish(Class<?> clazz, Object implObj){  
23.         //创建WebService服务工厂  
24.         JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();  
25.         //注册WebService接口  
26.         factory.setServiceClass(clazz);  
27.         //发布接口  
28.         factory.setAddress("http://localhost:9000/" +clazz.getSimpleName());  
29.         factory.setServiceBean(implObj);  
30. //        factory.getInInterceptors().add(new LoggingInInterceptor());   
31. //        factory.getOutInterceptors().add(new LoggingOutInterceptor());   
32.        factory.getInInterceptors().add(new SampleInterceptorService());  
33.         //创建WebService  
34.         factory.create();  
35.     }  
36. }  

package mysimplewebservicecxf01.publish;import java.util.ArrayList;import java.util.List;import mysimplewebservicecxf01.service.interceptor.SampleInterceptorService;import org.apache.cxf.jaxws.JaxWsServerFactoryBean;public class ServiceManager {private static final ServiceManager instance = new ServiceManager();List<String> serviceList = new ArrayList<String>();public static ServiceManager getInstance(){return instance;}private ServiceManager(){}public void publish(Class<?> clazz, Object implObj){//创建WebService服务工厂        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();        //注册WebService接口        factory.setServiceClass(clazz);        //发布接口        factory.setAddress("http://localhost:9000/" +clazz.getSimpleName());        factory.setServiceBean(implObj);//        factory.getInInterceptors().add(new LoggingInInterceptor()); //        factory.getOutInterceptors().add(new LoggingOutInterceptor());        factory.getInInterceptors().add(new SampleInterceptorService());        //创建WebService        factory.create();}}

4、最后在Activator的start函数中，使用ServiceManager 将服务发布出来

[java] view plaincopyprint?

1. package mysimplewebservicecxf01;  
2.   
3. import mysimplewebservicecxf01.publish.ServiceManager;  
4. import mysimplewebservicecxf01.user.api.IUserManager;  
5. import mysimplewebservicecxf01.user.impl.UserManager;  
6.   
7. import org.osgi.framework.BundleActivator;  
8. import org.osgi.framework.BundleContext;  
9.   
10. public class Activator implements BundleActivator {  
11.   
12.     private static BundleContext context;  
13.   
14.     public void start(BundleContext bundleContext) throws Exception {  
15.         Activator.context = bundleContext;  
16.           
17.         ServiceManager.getInstance().publish(IUserManager.class, new UserManager());  
18.     
19.     }  
20.   
21.     public void stop(BundleContext bundleContext) throws Exception {  
22.         Activator.context = null;  
23.     }  
24.   
25. }  

package mysimplewebservicecxf01;import mysimplewebservicecxf01.publish.ServiceManager;import mysimplewebservicecxf01.user.api.IUserManager;import mysimplewebservicecxf01.user.impl.UserManager;import org.osgi.framework.BundleActivator;import org.osgi.framework.BundleContext;public class Activator implements BundleActivator {private static BundleContext context;public void start(BundleContext bundleContext) throws Exception {Activator.context = bundleContext;ServiceManager.getInstance().publish(IUserManager.class, new UserManager());  }public void stop(BundleContext bundleContext) throws Exception {Activator.context = null;}}

• 客户端调用服务器
  

[java] view plaincopyprint?

1. package mysimplewebservicecxf01;  
2.   
3. import java.util.List;  
4.   
5. import mysimplewebservicecxf01.client.interceptor.SampleInterceptorClient;  
6. import mysimplewebservicecxf01.user.api.IUserManager;  
7. import mysimplewebservicecxf01.user.api.model.User;  
8.   
9. import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;  
10.   
11. public class Client {  
12.   
13.     public static void main(String[] args) {       
14.          
15.         IUserManager userMgr = (IUserManager) getService(IUserManager.class);  
16.         List<User> userList = userMgr.queryUsers();  
17.         int count = 0;  
18.         /*还不清楚为什么，当返回的List为空时，客户端收到的却是null*/  
19.         if(null != userList){  
20.             count = userList.size();  
21.               
22.         }  
23.         System.out.println("Count:"+count);  
24.           
25.         int userId01 = userMgr.addUser("User01");  
26.           
27.         userList = userMgr.queryUsers();  
28.         count = userList.size();  
29.         System.out.println("Count:"+count);  
30.           
31.         int userId02 = userMgr.addUser("User02");  
32.           
33.         userList = userMgr.queryUsers();  
34.         count = userList.size();  
35.         System.out.println("Count:"+count);  
36.           
37.         userMgr.deleteUser(userId02);  
38.           
39.         userList = userMgr.queryUsers();  
40.         count = userList.size();  
41.         System.out.println("Count:"+count);  
42.     }  
43.       
44.     public static Object getService(Class<?> clazz){  
45.         //创建WebService客户端代理工厂  
46.         JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();  
47.         //注册WebService接口  
48.         factory.setServiceClass(clazz);  
49.         //设置WebService地址  
50.         factory.setAddress("http://localhost:9000/"+clazz.getSimpleName());    
51.         factory.getOutInterceptors().add(new SampleInterceptorClient());  
52.         return factory.create();  
53.     }  
54.   
55. }
