【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：
[plain] view plaincopy
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: MySimpleWebServiceCXF01
Bundle-SymbolicName: MySimpleWebServiceCXF01
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: mysimplewebservicecxf01.Activator
Bundle-ActivationPolicy: lazy
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Import-Package: org.apache.commons.logging;version="1.0.4",
org.osgi.framework;version="1.3.0"
Bundle-ClassPath: lib/geronimo-activation_1.1_spec-1.1.jar,
lib/geronimo-annotation_1.0_spec-1.1.1.jar,

lib/jetty-security-7.5.4.v20111024.jar,
lib/stax2-api-3.1.1.jar,
lib/wstx-asl-3.2.0.jar
2、声明一个WebService服务接口并实现
WebService接口文件 IUserManager.java
[java] view plaincopy
package mysimplewebservicecxf01.user.api;
import java.util.List;
import javax.jws.WebService;
import mysimplewebservicecxf01.user.api.model.User;
@WebService
public 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 plaincopy
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 plaincopy
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;
@Override
public 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;
}
@Override
public 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;
}
@Override
public 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;
}
@Override
public 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 plaincopy
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 plaincopy
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 plaincopy
package mysimplewebservicecxf01;
import java.util.List;
import mysimplewebservicecxf01.client.interceptor.SampleInterceptorClient;
import mysimplewebservicecxf01.user.api.IUserManager;
import mysimplewebservicecxf01.user.api.model.User;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
public class Client {
public static void main(String[] args) {
IUserManager userMgr = (IUserManager) getService(IUserManager.class);
List<User> userList = userMgr.queryUsers();
int count = 0;
/*还不清楚为什么，当返回的List为空时，客户端收到的却是null*/
if(null != userList){
count = userList.size();
}
System.out.println("Count:"+count);
int userId01 = userMgr.addUser("User01");
userList = userMgr.queryUsers();
count = userList.size();
System.out.println("Count:"+count);
int userId02 = userMgr.addUser("User02");
userList = userMgr.queryUsers();
count = userList.size();
System.out.println("Count:"+count);
userMgr.deleteUser(userId02);
userList = userMgr.queryUsers();
count = userList.size();
System.out.println("Count:"+count);
}
public static Object getService(Class<?> clazz){
//创建WebService客户端代理工厂
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
//注册WebService接口
factory.setServiceClass(clazz);
//设置WebService地址
factory.setAddress("http://localhost:9000/"+clazz.getSimpleName());
factory.getOutInterceptors().add(new SampleInterceptorClient());
return factory.create();
}
}
