用cxf编写基于spring的webservice之上篇

用CXF编写基于spring的web service的步骤：

 

1.   Server端

–     创建spring的配置文件beans.xml,在其中配置SEI

–     在web.xml中，配置上CXF的一些核心组件

1.   Client端

–     生成客户端代码

–     创建客户端的spring配置文件beans-client.xml,并配置

–     编写测试类请求web service

下面通过编码实现：

服务端实体类：

 

package com.cxf.entity;/** * @author yxs * @since 2015年9月16日 上午10:17:00 */public class Order {private int id;private String name;private double price;public Order(int id, String name, double price) {super();this.id = id;this.name = name;this.price = price;}public Order() {super();}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public double getPrice() {return price;}public void setPrice(double price) {this.price = price;}@Overridepublic String toString() {return "Order [id=" + id + ", name=" + name + ", price=" + price + "]";}}

接口和实现类：

package com.cxf.ws;import javax.jws.WebMethod;import javax.jws.WebService;import com.cxf.entity.Order;/** * @author yxs * @since 2015年9月16日 上午10:17:54 */@WebServicepublic interface OrderWS {@WebMethodpublic Order getOrderById(int id);}

package com.cxf.ws;import javax.jws.WebService;import com.cxf.entity.Order;/** * @author yxs * @since 2015年9月16日 上午10:18:57 */@WebServicepublic class OrderWSImpl implements OrderWS {/* (non-Javadoc) * @see com.cxf.ws.OrderWS#getOrderById(int) */@Overridepublic Order getOrderById(int id) {// TODO Auto-generated method stubreturn new Order(id, "机票",1000);}}

配置文件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.xsdhttp://cxf.apache.org/jaxws http://cxf.apache.org/jaxws">    <!-- 引cxf的一些核心配置 -->   <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="orderWS" implementor="com.cxf.ws.OrderWSImpl" address="/orderws">      <!-- 加一个拦截器方便后面用jquery请求webservice的测试 -->    <jaxws:inInterceptors>     <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>       </jaxws:inInterceptors>     </jaxws:endpoint></beans>

web.xml:

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">  <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>    <!-- 配置beans.xml -->  <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:beans.xml</param-value>   </context-param>      <!--    应用启动的一个监听器    -->   <listener>      <listener-class>         org.springframework.web.context.ContextLoaderListener      </listener-class>   </listener>      <!--    所有请求都会先经过cxf框架    -->   <servlet>      <servlet-name>CXFServlet</servlet-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>/ws/*</url-pattern>    </servlet-mapping></web-app>

启动tomcat服务器，然后访问http://localhost:8088/cxf_spring_ws/ws/orderws?wsdl

就可以看到

<wsdl:definitions name="OrderWSImplService"targetNamespace="http://ws.cxf.com/"><wsdl:types><xs:schema elementFormDefault="unqualified" targetNamespace="http://ws.cxf.com/"version="1.0"><xs:element name="getOrderById" type="tns:getOrderById" /><xs:element name="getOrderByIdResponse" type="tns:getOrderByIdResponse" /><xs:complexType name="getOrderById"><xs:sequence><xs:element name="arg0" type="xs:int" /></xs:sequence></xs:complexType><xs:complexType name="getOrderByIdResponse"><xs:sequence><xs:element minOccurs="0" name="return" type="tns:order" /></xs:sequence></xs:complexType><xs:complexType name="order"><xs:sequence><xs:element name="id" type="xs:int" /><xs:element minOccurs="0" name="name" type="xs:string" /><xs:element name="price" type="xs:double" /></xs:sequence></xs:complexType></xs:schema></wsdl:types><wsdl:message name="getOrderByIdResponse"><wsdl:part element="tns:getOrderByIdResponse" name="parameters"></wsdl:part></wsdl:message><wsdl:message name="getOrderById"><wsdl:part element="tns:getOrderById" name="parameters"></wsdl:part></wsdl:message><wsdl:portType name="OrderWS"><wsdl:operation name="getOrderById"><wsdl:input message="tns:getOrderById" name="getOrderById"></wsdl:input><wsdl:output message="tns:getOrderByIdResponse" name="getOrderByIdResponse"></wsdl:output></wsdl:operation></wsdl:portType><wsdl:binding name="OrderWSImplServiceSoapBinding" type="tns:OrderWS"><soap:binding style="document"transport="http://schemas.xmlsoap.org/soap/http" /><wsdl:operation name="getOrderById"><soap:operation soapAction="" style="document" /><wsdl:input name="getOrderById"><soap:body use="literal" /></wsdl:input><wsdl:output name="getOrderByIdResponse"><soap:body use="literal" /></wsdl:output></wsdl:operation></wsdl:binding><wsdl:service name="OrderWSImplService"><wsdl:port binding="tns:OrderWSImplServiceSoapBinding" name="OrderWSImplPort"><soap:address location="http://localhost:8088/cxf_spring_ws/ws/orderws" /></wsdl:port></wsdl:service></wsdl:definitions>

说明发布成功.

新建一个web项目，将服务端的jar都拷过来，通过wsdl2java生成客户端代码

配置文件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.xsdhttp://cxf.apache.org/jaxws http://cxf.apache.org/jaxws"><jaxws:client id="orderClient" serviceClass="com.cxf.ws.OrderWS" address="http://localhost:8088/cxf_spring_ws/ws/orderws">     <jaxws:outInterceptors>            <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>     </jaxws:outInterceptors></jaxws:client></beans>

写一个测试类就可以看到输出的信息，表示客户端调用成功:

package com.cxf.ws;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;/** * @author yxs * @since 2015年9月16日 上午10:28:59 */public class TestCxf {     public static void main(String[] args) {   ApplicationContext applicationContext=new ClassPathXmlApplicationContext(new String[]  {"client-beans.xml"});       OrderWS bean = (OrderWS) applicationContext.getBean("orderClient");       Order order=bean.getOrderById(22);       System.out.println(order);}}

下一篇，我们用页面的js调用一个servlet，然后通过后台访问webservice,因为直接使用js访问webservice会存在跨域问题
