CXF+Spring使用笔记

来源：互联网发布：广州seo公司编辑：程序博客网时间：2024/06/05 23:54

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。

第一步:编写服务器端

1.编写DTO类

@XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "MyDto") public class MyDto implements Serializatable{ long id; long name; public MyDto(){}//如果需要传递列表,则必须要无参数的构造函数 public MyDto(long i){this.id = i;} }

2.编写服务接口

@WebServicepublic interface BbsWebService { public List<MyDto> findAllDto() throws Exception;}

3.编写服务类

@Service@WebService(endpointInterface = "cn.ait.mdp2.webservice.BbsWebService")public class BbsWebServiceImpl implements BbsWebService {@AutowiredArticleService articleService;@Overridepublic List<MyDto> findAllDto() throws Exception {return articleService.findRollingArticle();}}

4.发布服务:

5.修改web.xml

<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>/webservices/*</url-pattern></servlet-mapping>

第二步:编写客户段

有多种方式

1.通过spring注入:

<?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"default-autowire="byName" default-lazy-init="true"><bean id="client" class="cn.ait.mdp2.webservice.WebServiceSample"factory-bean="clientFactory" factory-method="create" /><bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"><property name="serviceClass" value="cn.ait.mdp2.webservice.WebServiceSample" /><property name="address"value="http://localhost:8080/mdp/webservices/WebServiceSample" /></bean><bean id="userClient" class="cn.ait.mdp2.webservice.UserWebService"factory-bean="userClientFactory" factory-method="create" /><bean id="userClientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"><property name="serviceClass" value="cn.ait.mdp2.webservice.UserWebService" /><property name="address"value="http://localhost:8080/mdp/webservices/UserWebService" /></bean><bean id="bbsClient" class="cn.ait.mdp2.webservice.BbsWebService"factory-bean="bbsClientFactory" factory-method="create" /><bean id="bbsClientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"><property name="serviceClass" value="cn.ait.mdp2.webservice.BbsWebService" /><property name="address"value="http://localhost:8080/mdp/webservices/BbsWebService" /></bean></beans>

2.直接使用JaxWsProxyFactoryBean:

public static void main(String[] args)throws Exception {// TODO Auto-generated method stubJaxWsProxyFactoryBean bean = new JaxWsProxyFactoryBean();bean.setServiceClass(BbsWebService.class);bean.setAddress("http://localhost:8080/mdp/webservices/BbsWebService");BbsWebService web = (BbsWebService)bean.create();List<Article> articleList = web.findPublicArticle();for(Article article:articleList){System.out.println(article.getContent());}}

安全:

服务器端:

<jaxws:endpoint id="bbsService" address="/BbsWebService" implementor="#bbsWebServiceImpl" ><jaxws:inInterceptors> <bean class="org.apache.cxf.ws.security.wss4j.WSS4JInInterceptor"> <constructor-arg> <map> <entry key="action" value="UsernameToken" /> <entry key="passwordType" value="PasswordText" /> <entry key="user" value="cxfServer" /> <entry key="passwordCallbackRef"> <ref bean="serverPasswordCallback" /> </entry> </map> </constructor-arg> </bean> </jaxws:inInterceptors> --></jaxws:endpoint> <bean id="serverPasswordCallback" class="cn.ait.mdp2.webservice.ServerPasswordCallback" />//需要验证令牌

客户端：

<jaxws:client id="bbsClient" address="http://localhost:8080/mdp/webservices/BbsWebService" serviceClass="cn.ait.mdp2.webservice.BbsWebService"> <jaxws:outInterceptors> <bean class="org.apache.cxf.ws.security.wss4j.WSS4JOutInterceptor"> <constructor-arg> <map> <entry key="action" value="UsernameToken" /> <entry key="passwordType" value="PasswordText" /> <entry key="user" value="cxfClient" /> <entry key="passwordCallbackRef"> <ref bean="clientPasswordCallback" /> </entry> </map> </constructor-arg> </bean> </jaxws:outInterceptors> </jaxws:client> <bean id="clientPasswordCallback" class="cn.ait.mdp2.webservice.ClientPasswordCallback" /> //需要提交客户端令牌

异常处理：

使用try..catch..进行异常处理

附件：

protected DataHandler data;//附件public DataHandler getData() {return data;}public void setData(DataHandler data) {this.data = data;}

@Overridepublic void uploadFile(UserDTO user) {//上传附件DataHandler data = user.getData();try{InputStream is = data.getInputStream();OutputStream os = new FileOutputStream(new File("c:/mtom.doc"));byte[] b = new byte[100000];int bytesRead = 0;while ((bytesRead = is.read(b)) != -1) {os.write(b, 0, bytesRead);}os.flush();os.close();is.close();}catch(Exception e){}}

服务气端：

<jaxws:endpoint id="deviceWebService" address="/DeviceWebService" implementor="#deviceWebServiceImpl" > <jaxws:properties><entry key="mtom-enabled" value="true"/></jaxws:properties></jaxws:endpoint>

客户端：

WebServiceSample webService = (WebServiceSample)context.getBean("webService");UserDTO user = new UserDTO();user.setId(1);user.setName("zhl");DataSource source = new FileDataSource(new File("c:/tttt.sql"));user.setData(new DataHandler(source));webService.uploadFile(user);
