基于Simple Fronted的WebService开发

采用Simple frontend方式开发WebService方式主要是使用Simple Factory组件基于反射的概念去构建和发布服务，不

需要在接口和实现类上添加注解。

完整代码参考http://springsfeng.iteye.com/blog/1634753附件。

1. 创建接口和实现类

package org.pcdp.sample.simplefrontend;

public interface OrderProcess {

	String processOrder(Order order);
}

package org.pcdp.sample.simplefrontend;

public class OrderProcessImpl implements OrderProcess {

	public String processOrder(Order order) {
		System.out.println("Processing order...");
		String orderID = validate(order);
		return orderID;
	}

	/**
	 * Validates the order and returns the order ID
	 **/
	private String validate(Order order) {

		String custID = order.getCustomerID();
		String itemID = order.getItemID();
		int qty = order.getQty();
		double price = order.getPrice();

		if (custID != null && itemID != null && !custID.equals("") && !itemID.equals("") && qty > 0 && price > 0.0) {
			return "ORD1234";
		}
		return null;
	}
}

 2. 创建Server端实现

import org.apache.cxf.frontend.ServerFactoryBean;

public class Server {

	public static void main(String[] arg) {
		
		// Create service implementation
		OrderProcessImpl orderProcessImpl = new OrderProcessImpl();

		// Create Server
		ServerFactoryBean svrFactory = new ServerFactoryBean();
		svrFactory.setServiceClass(OrderProcess.class);
		svrFactory.setAddress("http://localhost:8080/SimpleOrderProcess");
		svrFactory.setServiceBean(orderProcessImpl);
		svrFactory.create();
	}
}

3. 创建Client端实现

import org.apache.cxf.frontend.ClientProxyFactoryBean;
import org.pcdp.sample.simplefrontend.Order;
import org.pcdp.sample.simplefrontend.OrderProcess;

public class SimpleClient {

	public static void main(String[] args) {
		ClientProxyFactoryBean factory = new ClientProxyFactoryBean();
		factory.setServiceClass(OrderProcess.class);
		factory.setAddress("http://localhost:8080/SimpleOrderProcess");
		OrderProcess client = (OrderProcess) factory.create();

		Order order = new Order();
		order.setCustomerID("C001");
		order.setItemID("I001");
		order.setPrice(100.00);
		order.setQty(20);

		String result = client.processOrder(order);
		System.out.println("The order ID is " + result);
	}
}
