四、CXF WebService中传递复杂类型对象

前面介绍的都是传递简单的字符串，现在开始介绍传递复杂类型的对象。如JavaBean、Array、List、Map等。

1、 首先看看服务器端的代码所需要的JavaBean对象

package com.hoo.entity;

import java.io.Serializable;

/**
 * <b>function:</b>User Entity
 * @author hoojo
 * @createDate Dec 16, 2010 10:20:02 PM
 * @file User.java
 * @package com.hoo.entity
 * @project AxisWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
public class User implements Serializable {
    private static final long serialVersionUID = 677484458789332877L;
    private int id;
    private String name;
    private String email;
    private String address;

    //getter、setter

    @Override
    public String toString() {
        return this.id + "#" + this.name + "#" + this.email + "#" + this.address;
    }
}

下面的是集合传递Users，CXF直接传递集合对象会出现异常，用一个对象包装下就Ok了，不知道是什么原因。异常信息如下：

DefaultValidationEventHandler: [ERROR]: unexpected element(uri:"", local:"item")
org.apache.cxf.interceptor.Fault: Unmarshalling Error: unexpected element (uri:"", local:"item")

package com.hoo.entity;

import java.util.HashMap;
import java.util.List;

/**
 * <b>function:</b> Users Entity
 * @author hoojo
 * @createDate 2011-3-18 上午09:27:31
 * @file Users.java
 * @package com.hoo.entity
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
public class Users {
    private List<User> users;
    private User[] userArr;
    private HashMap<String, User> maps;

    //getter、setter方法
}

2、 下面看看复杂对象传递的服务器端代码

package com.hoo.service;

import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
import com.hoo.entity.User;
import com.hoo.entity.Users;

/**
 * <b>function:</b> WebService传递复杂对象，如JavaBean、Array、List、Map等
 * @author hoojo
 * @createDate 2011-3-18 上午08:22:55
 * @file ComplexUserService.java
 * @package com.hoo.service
 * @project CXFWebService

 * @email hoojo_@126.com
 * @version 1.0
 */
@WebService
@SOAPBinding(style = Style.RPC)
@SuppressWarnings("deprecation")
public class ComplexUserService {

    public User getUserByName(@WebParam(name = "name") String name) {
        User user = new User();
        user.setId(new Date().getSeconds());
        user.setName(name);
        user.setAddress("china");
        user.setEmail(name + "@hoo.com");
        return user;
    }

    public void setUser(User user) {
        System.out.println("############Server setUser###########");
        System.out.println("setUser:" + user);
    }

    public Users getUsers(int i) {
        List<User> users = new ArrayList<User>();
        for (int j = 0; j <= i; j++) {
            User user = new User();
            user.setId(new Date().getSeconds());
            user.setName("jack#" + j);
            user.setAddress("china");
            user.setEmail("jack" + j + "@hoo.com");
            users.add(user);
        }
        Users u = new Users();
        u.setUsers(users);
        return u;
    }

    public void setUsers(Users users) {
        System.out.println("############Server setUsers###########");
        for (User u : users.getUsers()) {
            System.out.println("setUsers:" + u);
        }
    }

    public Users getUserArray(int i) {
        User[] users = new User[i];
        for (int j = 0; j < i; j++) {
            User user = new User();
            user.setId(new Date().getSeconds());
            user.setName("jack#" + j);
            user.setAddress("china");
            user.setEmail("jack" + j + "@hoo.com");
            users[j] = user;
        }
        Users u = new Users();
        u.setUserArr(users);
        return u;
    }

    public void setUserArray(Users users) {
        System.out.println("############Server setUserArray###########");
        for (User u : users.getUserArr()) {
            System.out.println("setUserArray:" + u);
        }
    }

    public void setUserMap(Users maps) {
        System.out.println("############Server setUserMap###########");
        System.out.println("setUserMap:" + maps.getMaps());
    }

    public Users getUserMap() {
        HashMap<String, User> users = new HashMap<String, User>();
        User user = new User();
        user.setId(new Date().getSeconds());
        user.setName("jack#");
        user.setAddress("china#");
        user.setEmail("jack@hoo.com");
        users.put("A", user);

        user = new User();
        user.setId(new Date().getSeconds());
        user.setName("tom");
        user.setAddress("china$$");
        user.setEmail("tom@hoo.com");
        users.put("B", user);
        Users u = new Users();
        u.setMaps(users);

        return u;
    }
}

3、 发布WebService的代码

package com.hoo.service.deploy;

import com.hoo.service.ComplexUserService;

/**
 * <b>function:</b> 发布ComplexUserService服务
 * @author hoojo
 * @createDate 2011-3-18 上午08:28:57
 * @file DeployComplexUserService.java
 * @package com.hoo.service.deploy
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
public class DeployComplexUserService {

    public static void main(String[] args) throws InterruptedException {
        String address = "http://localhost:9000/complexUser";
        DeployUtils.deployService(address, new ComplexUserService());
        Thread.sleep(1000 * 60 * 20);
        System.exit(0);
        System.out.println("Server exit ");
    }
}

DeployUtils.java

package com.hoo.service.deploy;

import javax.xml.ws.Endpoint;

/**
 * <b>function:</b> 发布WebService工具类
 * @author hoojo
 * @createDate Mar 17, 2011 8:14:05 PM
 * @file DeployUtils.java
 * @package com.hoo.service.deploy
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
public final class DeployUtils {
    /**
     * <b>function:</b>发布WebService
     * @author hoojo
     */
    public static void deployService(String address, Object service) {
        System.out.println("Server start ……");
        Endpoint.publish(address, service);
    }
}

4、 通过发布后的地址的http://localhost:9000/complexUser?wsdl; wsdl中的内容定制你的客户端调用WebService的接口，当然你也可以让服务器端实现一个接口。

package com.hoo.service;

import javax.jws.WebParam;
import javax.jws.WebService;
import com.hoo.entity.User;
import com.hoo.entity.Users;

/**
 * <b>function:</b>定制客户端请求WebService所需要的接口
 * @author hoojo
 * @createDate 2011-3-18 上午08:22:55
 * @file ComplexUserService.java
 * @package com.hoo.service
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
@WebService
public interface IComplexUserService {

    public User getUserByName(@WebParam(name = "name") String name);

    public void setUser(User user);

    public Users getUsers(int i);

    public void setUsers(Users users);

    public Users getUserArray(int i);

    public void setUserArray(Users users);

    public void setUserMap(Users maps);

    public Users getUserMap();
}

5、 客户端调用代码

package com.hoo.client;

import java.util.ArrayList;
import java.util.List;
import java.util.Random;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.hoo.entity.User;
import com.hoo.entity.Users;
import com.hoo.service.IComplexUserService;

/**
 * <b>function:</b>调用ComplexUserService客户端
 * @author hoojo
 * @createDate 2011-3-18 上午08:37:11
 * @file ComplexUserServiceClient.java
 * @package com.hoo.client
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
public class ComplexUserServiceClient {

    public static void main(String[] args) {
        //调用WebService
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setServiceClass(IComplexUserService.class);
        factory.setAddress("http://localhost:9000/complexUser");

        IComplexUserService service = (IComplexUserService) factory.create();

        System.out.println("#############Client getUserByName##############");
        User user = service.getUserByName("hoojo");
        System.out.println(user);

        user.setAddress("China-Guangzhou");
        service.setUser(user);

        System.out.println("#############Client getUsers##############");
        Users users = service.getUsers(4);
        System.out.println(users);
        List<User> tempUsers = new ArrayList<User>();
        for (User u : users.getUsers()) {
            System.out.println(u);
            u.setName("hoojo" + new Random().nextInt(100));
            u.setAddress("Chian-GuangZhou#" + new Random().nextInt(100));
            tempUsers.add(u);
        }
        users.getUsers().clear();
        users.getUsers().addAll(tempUsers);
        service.setUsers(users);

        System.out.println("#############Client getUserArray##############");
        users = service.getUserArray(4);
        User[] userArr = new User[4];
        int i = 0;
        for (User u : users.getUserArr()) {
            System.out.println(u);
            u.setName("hoojo" + new Random().nextInt(100));
            u.setAddress("Chian-ShenZhen#" + new Random().nextInt(100));
            userArr[i] = u;
            i ++;
        }

        users.setUserArr(userArr);
        service.setUserArray(users);

        System.out.println("##################Client getUserMap###############");
        users = service.getUserMap();
        System.out.println(users.getMaps());
        users.getMaps().put("ABA", userArr[0]);
        service.setUserMap(users);
    }
}

6、 运行后结果如下

控制台客户端结果：
