【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/geronimo-jaxws_2.2_spec-1.1.jar,
lib/geronimo-servlet_2.5_spec-1.1.2.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();
    }

}
