前言：好记性不如烂笔头，写博客的好处是，以前接触的东西即便忘记了，也可以从这里查找。
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 。可以与Spring进行快速无缝的整合。灵活的部署，可以运行在Tomcat,Jboss,Jetty(内置),IBMWS,BeaWL上面。
更多CXF介绍：http://www.ibm.com/developerworks/cn/education/java/j-cxf/
一、cxf发布服务的类
用两个不同的类发布应用：
a. ServerFactoryBean -- FacotryBean
b. JaxWsServerFactoryBean(建议使用此类)
服务端与客户端类的使用映射关系如下图所示：
二、使用ServerFactoryBean类发布标准的webservice服务
下载cxf安装包apache-cxf-2.4.2，里面lib下jar包以供项目所有。
1.服务端
a.新建web项目，加入cxf的jar包
b.定义webservice的接口
package com.wp.service; import javax.jws.WebService; @WebService public interface HelloWs { public String sayHello(String name); }
c.定义webservice接口的实现类
package com.wp.service; public class HelloWsImpl implements HelloWs { @Override public String sayHello(String name) { return "hello" + name; } }
d.发布webservice服务
package com.wp.service; import org.apache.cxf.frontend.ServerFactoryBean; public class Server { public static void main(String[] args) { ServerFactoryBean sfb = new ServerFactoryBean(); //1.服务提供者实现的接口 sfb.setServiceClass(HelloWs.class); //2.指定访问路径 sfb.setAddress("http://localhost:9090/ws"); //3.指定服务实现类 sfb.setServiceBean(new HelloWsImpl()); //4.发布 sfb.create(); System.out.println("发布成功..."); } }
2.客户端
a.使用wsdl2java生成客户端代码调用服务（之前有解释，这里就不做解释了）
b.使用ClientProxyFactoryBean类调用service服务
客户端必须加入cxf的jar包
浏览器访问http://localhost:9090/ws?wsdl ，查看service和operation
1) 不同项目中调用
package com.wp.test; import com.wp.client.HelloWs; import com.wp.client.HelloWsPortType; public class Client { public static void main(String[] args) { HelloWs hw = new HelloWs(); HelloWsPortType h = hw.getHelloWsPort(); String result = h.sayHello("小强"); System.out.println(result); } }
1) 在同一项目中调用
package com.wp.service; import org.apache.cxf.frontend.ClientProxyFactoryBean; public class Client { public static void main(String[] args) { ClientProxyFactoryBean cfb = new ClientProxyFactoryBean(); cfb.setAddress("http://localhost:9090/ws"); cfb.setServiceClass(HelloWs.class); HelloWs hw = (HelloWs) cfb.create(); System.out.println(hw.sayHello("明明")); } }
类似的例子在apache-cxf-2.4.2安装包下的samples中，开发的时候可以查看
三、使用JaxWsServerFactoryBean类发布服务
1.服务端
package com.wp.service; import javax.jws.WebParam; import javax.jws.WebService; @WebService public interface HelloWs { public String sayHello(@WebParam(name="text") String text); }
package com.wp.service; import javax.jws.WebService; @WebService(endpointInterface = "com.wp.service.HelloWs") public class HelloWsImpl implements HelloWs { @Override public String sayHello(String name) { return "hello " + name; } }
package com.wp.service; import org.apache.cxf.interceptor.LoggingInInterceptor; import org.apache.cxf.interceptor.LoggingOutInterceptor; import org.apache.cxf.jaxws.JaxWsServerFactoryBean; public class Server { public static void main(String[] args) { JaxWsServerFactoryBean jsfb = new JaxWsServerFactoryBean(); //1.服务提供者实现的接口 jsfb.setServiceClass(HelloWs.class); //2.指定访问路径 jsfb.setAddress("http://localhost:9090/ws"); //3.指定服务实现类 jsfb.setServiceBean(new HelloWsImpl()); //jsfb.getInInterceptors().add(new LoggingInInterceptor()); //jsfb.getOutInterceptors().add(new LoggingOutInterceptor()); //4.发布 jsfb.create(); System.out.println("发布成功..."); } }
2.客户端
生成客户端代码：
a.在不同项目中
package com.wp.test; import org.apache.cxf.frontend.ClientProxyFactoryBean; import org.apache.cxf.interceptor.LoggingInInterceptor; import org.apache.cxf.interceptor.LoggingOutInterceptor; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; import com.wp.client.HelloWs; public class Client { public static void main(String[] args) { JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); // factory.getInInterceptors().add(new LoggingInInterceptor()); // factory.getOutInterceptors().add(new LoggingOutInterceptor()); factory.setAddress("http://localhost:9090/ws"); HelloWs client = factory.create(HelloWs.class); System.out.println(client.sayHello("World")); } }
b.在同一项目中
package com.wp.service; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; public class Client { public static void main(String[] args) { JaxWsProxyFactoryBean bean = new JaxWsProxyFactoryBean(); bean.setAddress("http://localhost:9090/ws"); bean.setServiceClass(HelloWs.class); HelloWs hw = (HelloWs) bean.create(); System.out.println(hw.sayHello("www")); } }
四、spring和cxf的集成（MyEclipse）jaxws:server配置
CXF原生支持spring，可以和Spring无缝集成。本例通过tomcat启动容器来启动cxf服务。
1.新建一个maven项目（写过一个随笔），并且加入jar包
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.wp.test</groupId> <artifactId>cxfmaven</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>cxfmaven Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <spring.version>3.2.5.RELEASE_BUNDLE</spring.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-asm</artifactId> <version>3.0.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http</artifactId> <version>2.4.2</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxws</artifactId> <version>2.4.2</version> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http</artifactId> <version>2.4.2</version> </dependency> <!-- Jetty is needed if you're using the CXFServlet --> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http-jetty</artifactId> <version>2.4.2</version> </dependency> </dependencies> <build> <finalName>cxfmaven</finalName> </build> </project>
2.让spring管理ServerFactoryBean
<?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" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd "> <!-- 1 导入cxf发布的命名空间 xmlns:jaxws="http://cxf.apache.org/jaxws" http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd 2 通过配置发布webservice服务 2.1 发布简单的webservice服务(不需要定义服务器的接口 ，了解) <jaxws:endpoint address="" implementor=""> </jaxws:endpoint> 2.2 发布标准的webservice服务 2.2.1 发布的地址 address 2.2.2 发布的服务器实现的接口 serviceClass 2.2.3 指定服务具体提供者（实现类对象） jaxws:serviceBean --> <!-- 实例化一个JaxWsServerFactoryBean对象 --> <jaxws:server address="/helloWs" serviceClass="com.wp.service.HelloWs"> <jaxws:serviceBean> <bean class="com.wp.service.HelloWsImpl"></bean> </jaxws:serviceBean> </jaxws:server> </beans>
3.cxf集成到web容器中
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>cxf</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <!-- 初始化CXFServlet --> <init-param> <param-name>config-location</param-name> <param-value>classpath:beans.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>cxf</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app>
4.启动web容器发布webservice服务
wsdl访问地址：http://localhost:8080/wsService/helloWs?wsdl
- 通过Eclipse中的Web Services Explorer进行测试；
- 建立一个客户端项目进行测试，跟上面一样。
