近些年来,Spring一直很火,许多框架都能跟Spring完美集成,CXF也不例外。下面,我就介绍一下如何使用CXF + Spring发布webService。我们还是使用前两篇博客使用的实例。
服务端:
目录结构:
这里需要的所有Spring的包,CXF的lib目录下都有。
IHelloWorldServer代码:
package com.test.server;
import javax.jws.WebService;
@WebService
public interface IHelloWorldServer {
public String sayHello(String username);
}
HelloWorldServerImp代码:
package com.test.server;
import javax.jws.WebService;
@WebService(endpointInterface="com.test.server.IHelloWorldServer",serviceName="HelloService")
public class HelloWorldServerImp implements IHelloWorldServer {
@Override
public String sayHello(String username) {
return username+" : HelloWorld";
}
}
applicationContext-server.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<jaxws:endpoint id="helloService" implementor="com.test.server.HelloWorldServerImp"
address="/helloService" />
</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" 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"
id="WebApp_ID" version="3.0">
<display-name>cxf_demo</display-name>
<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>
<display-name>cxf_demo</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-server.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<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>
其实这种方式与我们手动写Servlet并没有本质的区别,只不过这里让Spring代劳罢了。
以上就是服务端的代码,直接发布项目即可。发布完成后,输入网址:http://localhost:8080/cxf_demo1/ws 查看发布的WebService。
客户端:
这次我们不采用动态客户端,而是引用服务的接口实现。
目录结构:
红色方框中的jar就是我们用服务端的接口生成的jar。
applicationContext-client.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.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.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" />
<bean id="client" class="com.test.server.IHelloWorldServer"
factory-bean="clientFactory" factory-method="create" />
<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="com.test.server.IHelloWorldServer" />
<property name="address"
value="http://localhost:8080/cxf_demo1/ws/helloService" />
<!-- value="http://localhost:8080/cxf_demo_noSpring_1/ws/helloWorld" /> -->
</bean>
</beans>
HelloWorldClient代码:
package com.test.client;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.test.server.IHelloWorldServer;
public class HelloWorldClient {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext(
"applicationContext-client.xml");
IHelloWorldServer helloService = (IHelloWorldServer) context
.getBean("client");
String response = helloService.sayHello("haitao");
System.out.println(response);
}
}
run后结果如下:
到这里,Spring+CXF发布WebService完美实现。
我们可以看到,这次客户端实现没有用动态方式,这样就必须要用到服务端的接口jar包,这样的实现效率要比动态方式高,不过需要引用服务端jar包有时候是让人无法接受的。
关于CXF,我就先介绍这么多,学会这些只能说关于WebService你才刚刚入门,更多东西还有待于进一步研究、发现。
