CXF学习02---处理JavaBean类型与List的集合类型

整体框架与上一篇文章一样，只不过在Web Service接口中新添加了一个方法，List<Cat> getCatsByUser(User user);

用来处理JavaBean的参数与List的返回值。

新添加两个JavaBean，

package com.onyas.ws.cxf.domain;

public class Cat {

	private Integer id;
	private String color;
	private String name;
	
	public Cat() {
	}
	
	
	public Cat(Integer id, String color, String name) {
		super();
		this.id = id;
		this.color = color;
		this.name = name;
	}
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getColor() {
		return color;
	}
	public void setColor(String color) {
		this.color = color;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
	
	
}

package com.onyas.ws.cxf.domain;

public class User {

	private Integer id;
	private String username;
	private String password;
	private String address;
	
	public User() {
	}
	
	public User(Integer id, String username, String password, String address) {
		super();
		this.id = id;
		this.username = username;
		this.password = password;
		this.address = address;
	}
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result
				+ ((password == null) ? 0 : password.hashCode());
		result = prime * result
				+ ((username == null) ? 0 : username.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		User other = (User) obj;
		if (password == null) {
			if (other.password != null)
				return false;
		} else if (!password.equals(other.password))
			return false;
		if (username == null) {
			if (other.username != null)
				return false;
		} else if (!username.equals(other.username))
			return false;
		return true;
	}
	
	
	
}

在Web Service实现类中加入以下方法

@Override
	public List<Cat> getCatsByUser(User user) {
		//在实际的项目中，Web Service组件自已并不会去实现业务功能，
		//它只是调用业务逻辑组件的方法来暴露Web Service。
		UserService us = new UserServiceImpl();
		return us.getCatsByUser(user);
	}

因此还要新建一个业务接口

package com.onyas.ws.cxf.service;

import java.util.List;

import com.onyas.ws.cxf.domain.Cat;
import com.onyas.ws.cxf.domain.User;

public interface UserService {

	List<Cat> getCatsByUser(User user);

}

还有业务实现类

package com.onyas.ws.cxf.service.impl;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;


import com.onyas.ws.cxf.domain.Cat;
import com.onyas.ws.cxf.domain.User;
import com.onyas.ws.cxf.service.UserService;

public class UserServiceImpl implements UserService {

	// 用一个HashMap来模拟内存中的数据库
	static Map<User, List<Cat>> catDb = new HashMap<User, List<Cat>>();
	static {
		List<Cat> catList1 = new ArrayList<Cat>();
		catList1.add(new Cat(1, "红色", "红眼猫"));
		catList1.add(new Cat(2, "蓝色", "机器猫"));
		catDb.put(new User(1, "小明", "123", "上海"), catList1);

		List<Cat> catList2 = new ArrayList<Cat>();
		catList2.add(new Cat(3, "黑色", "加菲"));
		catList2.add(new Cat(4, "白色", "小白"));
		catDb.put(new User(2, "小红", "123", "北京"), catList2);
	}

	@Override
	public List<Cat> getCatsByUser(User user) {
		return catDb.get(user);
	}

}

其它地方不变，然后可以发布Web Service了。

重新用wsdl2java生成客户端代码，客户端架构也一样，

如下所示：

package onyas;

import java.util.List;

import com.onyas.ws.cxf.Cat;
import com.onyas.ws.cxf.HelloWorld;
import com.onyas.ws.cxf.User;
import com.onyas.ws.cxf.impl.HelloWorldWs;


public class ClentMain {

	public static void main(String[] args) {
		
		HelloWorldWs factory = new HelloWorldWs();
		//此处返回的只是远程Web Service的代理
		HelloWorld hw = factory.getHelloWorldWsPort();
		System.out.println(hw.sayHi("Test"));
		
		User user = new User();
		user.setUsername("小明");
		user.setPassword("123");
		List<Cat> cats = hw.getCatsByUser(user);
		for(Cat cat:cats){
			System.out.println(cat.getName());
		}
	}
	
}

运行客户端代码

显示内容如下：

Hello TestFri May 02 14:24:00 CST 2014
红眼猫
机器猫
