webservice之CXF注解实现（一）

1.关于CXF(摘自百度百科)

Apache CXF = Celtix + XFire，开始叫 Apache CeltiXfire，后来更名为 Apache CXF 了，以下简称为 CXF。CXF 继承了 Celtix 和 XFire 两大开源项目的精华，提供了对 JAX-WS 全面的支持，并且提供了多种 Binding 、DataBinding、Transport 以及各种 Format 的支持，并且可以根据实际项目的需要，采用代码优先（Code First）或者 WSDL 优先（WSDL First）来轻松地实现 Web Services 的发布和使用。Apache CXF已经是一个正式的Apache顶级项目。
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。

2.下载

http://cxf.apache.org/download.html

3.集成到eclipse

笔者下载的版本是2.7.7，进入apache-cxf-2.7.7/lib目录，将所需jar包复制到工程中，需要的jar包较多，如图：

4.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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">  <display-name>PortalService</display-name>   <!-- cfx webSerivice -->    <servlet>      <servlet-name>cxf</servlet-name>      <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>      <load-on-startup>1</load-on-startup>      </servlet>          <servlet-mapping>        <servlet-name>cxf</servlet-name>      <url-pattern>/services/*</url-pattern>      </servlet-mapping>      <session-config>        <session-timeout>60</session-timeout>      </session-config></web-app>

5.cxf-servlet.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"       xmlns:soap="http://cxf.apache.org/bindings/soap"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://cxf.apache.org/bindings/soap http://cxf.apache.org/schemas/configuration/soap.xsdhttp://cxf.apache.org/jaxwshttp://cxf.apache.org/schemas/jaxws.xsd"><!-- ;服务接口 -->   <jaxws:server id="jaxwsService" serviceClass="com.look.service.IService" address="/test"> <!-- address为服务发布二级地址 完整地址为 /项目发布名称/cfx拦截地址/address   (cfx拦截地址在web.xml中url-pattern标签中配置)  -->       <jaxws:serviceBean>         <!--服务实现类 -->                <bean class="com.look.service.IServiceImpl" />       </jaxws:serviceBean>   </jaxws:server></beans>

6.IService.java

package com.look.service;import javax.jws.WebMethod;import javax.jws.WebParam;import javax.jws.WebService;import com.protal.model.RequestCondition;@WebServicepublic interface IService{    @WebMethod    String test(@WebParam  RequestCondition requestCondition); }

网上的例子多是String类型，这里使用了自定义的Java类型，RequestCondition类的代码这里不贴出了，读者可自行建立该bean，添加属性age并添加相应的set、get方法

7.IServiceImpl.java

package com.look.service;import com.protal.model.RequestCondition;public class IServiceImpl implements IService{    @Override    public String test(RequestCondition requestCondition)    {       return “年龄是：”+requestCondition.getAge();    }}

8.部署并测试

将项目部署到web服务器，如tomcat

编写测试类

package com.look.utest;import org.apache.cxf.interceptor.LoggingInInterceptor;import org.apache.cxf.interceptor.LoggingOutInterceptor;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;import com.look.service.IService;import com.protal.model.RequestCondition;public class Test {public static void main(String[] args) {JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();      factory.getInInterceptors().add(new LoggingInInterceptor());      factory.getOutInterceptors().add(new LoggingOutInterceptor());      factory.setServiceClass(IService.class);      factory.setAddress("http://localhost:8080/PortalService/services/test");      IService client = (IService) factory.create();    RequestCondition requestCondition = new RequestCondition();    requestCondition.setAge("18");    String msg =  client.test(requestCondition);    System.out.println(msg);}}
