Webservice实战

参考链接：http://cxf.apache.org/docs/writing-a-service-with-spring.html

先说下cxf是什么东西吧：

Apache CXF 是一个开源的 Services 框架，CXF 帮助您利用 Frontend 编程 API 来构建和开发 Services ，像 JAX-WS 。这些 Services 可以支持多种协议，比如：SOAP、XML/HTTP、RESTful HTTP 或者 CORBA ，并且可以在多种传输协议上运行，比如：HTTP、JMS 或者 JBI，CXF 大大简化了 Services 的创建，同时它继承了 XFire 传统，一样可以天然地和 Spring 进行无缝集成。

 

一、SEI的定义

假设有以下SEI定义：

@WebService
public interface OrderProcess {
    public String processOrder(Order order);
}

 （实现端省略）

 

二、Server端发布

则最简单的发布Server的方式可以如下：

 

Endpoint.publish("http://localhost:8181/orderProcess", new OrderProcessImpl());

 

或者是spring的方式：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    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
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <import resource="classpath:META-INF/cxf/cxf.xml" />
    <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

    <jaxws:endpoint id="orderProcess"
        implementor="com.liulutu.liugang.cxf.jaxws.OrderProcessImpl" address="http://localhost:8090/orderProcess" />
</beans>

 三、Client端调用

Service service = Service.create(new URL("<wsdlfilepath>"),
        new QName("namespace", "servicename"));
OrderProcess port = orderProcessService.getPort(OrderProcess.class);
String s = port.processOrder(<arg>);
System.out.println(s);

 或者Spring的方式：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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.liulutu.liugang.cxf.codefirst.OrderProcess"
                  address="http://localhost:8181/orderProcess" />
</beans>

 然后在java代码里：

ClassPathXmlApplicationContext xmlApplicationContext = new ClassPathXmlApplicationContext(
      "/META-INF/spring/jaxwsspringclient.xml");
OrderProcess bean = xmlApplicationContext.getBean(OrderProcess.class);
System.out.println(bean.processOrder(<order>));
