WebService學習筆記-使用CXF編寫基於Spring的Webservice

新建Web工程，目錄結構如圖

Order.java實體類

public class Order {
	private int id;
	private String name;
	private double price;
	///...省略getter setter toString方法
	public Order() {//無參構造函數
		super();
	}
}

OrderWS.java接口

package com.umgsai.ws;

import javax.jws.WebMethod;
import javax.jws.WebService;

import com.umgsai.beans.Order;
@WebService
public interface OrderWS {

	@WebMethod
	public Order getOrderById(int id);
}

OrderWSImpl.java實現接口

package com.umgsai.ws.impl;

import com.umgsai.beans.Order;
import com.umgsai.ws.OrderWS;

public class OrderWSImpl implements OrderWS{

	@Override
	public Order getOrderById(int id) {
		System.out.println("Server getOrderById:" + id);
		return new Order(id, "Car", 200000);
	}

}

啓動項目

http://localhost:8080/WS_spring/orderWS?wsdl 能夠查看發佈的服務

源碼 http://yunpan.cn/cg4kLXaK8k5HS （提取碼：7c34）

---

客戶端調用上面發佈的服務。

使用CXF自帶的工具生成客戶端代碼

apache-cxf-3.0.1\bin>wsdl2java  http://localhost:8080/WS_spring/orderWS?wsdl

client-beans-xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:jaxws="http://cxf.apache.org/jaxws"
	xsi:schemaLocation="
	http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
	<jaxws:client id="orderClient" serviceClass="com.umgsai.ws.OrderWS"
		address="http://localhost:8080/WS_spring/orderWS" />
</beans>

client.java 客戶端代碼

package com.umgsai.ws.client;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.umgsai.ws.Order;
import com.umgsai.ws.OrderWS;

public class Client {
	public static void main(String[] args) {
		ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("client-beans.xml");
		OrderWS orderWS = (OrderWS) applicationContext.getBean("orderClient");
		Order order = orderWS.getOrderById(23);
		System.out.println(order);
	}
}

客戶端打印結果

Order [id=23, name=Car, price=200000.0]

服務器端打印結果

Server getOrderById:23
