基于cxf webservice(1)
由于cxf的框架能集成到Spring中，所以在实际项目中开发webservice多采取此种模式的，接下来的时间基于印度人写的ApacheCXFWebServiceDevelopment这本书留下痕迹，用以证明自己曾经学习过，努力过，也无奈过……。
一、webservice服务端的建立
首先建立一个web工程目录结构如下：
Order.java
package demo.order;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name="Order")
public class Order {
private String customerId;
private String itemId;
private int qty;
private double price;
public String getCustomerId() {
return customerId;
}
public void setCustomerId(String customerId) {
this.customerId = customerId;
}
public String getItemId() {
return itemId;
}
public void setItemId(String itemId) {
this.itemId = itemId;
}
public int getQty() {
return qty;
}
public void setQty(int qty) {
this.qty = qty;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public Order(String customerId, String itemId, int qty, double price) {
super();
this.customerId = customerId;
this.itemId = itemId;
this.qty = qty;
this.price = price;
}
public Order() {
super();
}
@Override
public String toString() {
return "Order [customerId=" + customerId + ", itemId=" + itemId
+ ", qty=" + qty + ", price=" + price + "]";
}
}
OrderProcess.java
package demo.order;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public interface OrderProcess {
@WebMethod
String processOrder(Order order);
}
OrderProcessImpl.java
package demo.order;
import javax.jws.WebService;
@WebService
public class OrderProcessImpl implements OrderProcess {
public OrderProcessImpl(){
//提示发布成功
System.out.println("..........AA...AA.........");
}
private String validate(Order order) {
String orderId = validate(order);
System.out.println("发布成功！");
return orderId;
}
@Override
public String processOrder(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;
}
}
最后就是配置文件
bean.xml
注意：新版的和书上有差别，查看官方配置文件：http://cxf.apache.org/docs/writing-a-service-with-spring.html
<?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://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <jaxws:endpoint id="orderProcess" implementor="demo.order.OrderProcessImpl" address="/orderprocess" /> </beans>
最后就是web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>webService2</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>beans.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<servlet>
<servlet-name>CXFServlet</servlet-name>
<display-name>CXF Servlet</display-name>
<servlet-class>
org.apache.cxf.transport.servlet.CXFServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
由于我们建立的是web工程，所以不用写测试类去调用SEI的publish函数去发布了，直接是把我们这个工程发布到server上就可以了。
在浏览器上我们输入：http://localhost:8080/webService2/orderprocess?wsdl
可以看到如下文件内容：
<?xml version='1.0' encoding='UTF-8'?><wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://order.demo/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" name="OrderProcessImplService" targetNamespace="http://order.demo/">

</wsdl:port>
</wsdl:service>
</wsdl:definitions>WSDL文件就是webService交互的核心文件。看到如上wsdl文件，证明我们的服务端启动成功。
二、客户端（本例中我们是把服务器端和客户端放在一个项目中了）
在上述图片中的demo.order.client中建立如图的两个文件
Client.javapackage demo.order.client;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import demo.order.Order;
import demo.order.OrderProcess;
public final class Client {
public Client() {}
public static void main(String[] args) {
ApplicationContext act = new ClassPathXmlApplicationContext(new String[]{"demo\\order\\client\\client-beans.xml"});
OrderProcess client = (OrderProcess) act.getBean("orderClient");
Order order = new Order();
order.setCustomerId("C001");
order.setItemId("I001");
order.setQty(100);
order.setPrice(2000.10);
String orderId = client.processOrder(order);
String message = (orderId == null)?"order not approved":"order approved;order id is "+orderId;
System.out.println(message);
System.exit(0);
}
}
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://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <jaxws:client id="orderClient" serviceClass="demo.order.OrderProcess" address="http://localhost:8080/webService2/orderprocess"/> </beans>
运行测试函数main，
得到如下结果：
