在Spring中采用CXF来使用WebService是很方便的,这是按照Apache官方网站上的文章写的。
1.Web服务接口HelloWorld.java:
package demo.spring; import javax.jws.WebService; @WebService public interface HelloWorld { String sayHi(String text); }
2.实现类HelloWorldImpl.java:
package demo.spring; import javax.jws.WebService; @WebService(endpointInterface = "demo.spring.HelloWorld") public class HelloWorldImpl implements HelloWorld { public String sayHi(String text) { return "Hello " + text; } }
3.Spring配置文件beans.xml:
<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/schema/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" /> <jaxws:endpoint id="helloWorld" implementor="demo.spring.HelloWorldImpl" address="/HelloWorld" /> </beans>
4.在web.xml文件中加入:
<context-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/beans.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>/*</url-pattern> </servlet-mapping>
5.客户端调用时Client.java:
package demo.spring.client; import demo.spring.HelloWorld; import org.springframework.context.support.ClassPathXmlApplicationContext; public final class Client { private Client() { } public static void main(String args[]) throws Exception { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"demo/spring/client/client-beans.xml"}); HelloWorld client = (HelloWorld)context.getBean("helloWorld"); String response = client.sayHi("Joe"); System.out.println("Response: " + response); } }
client-beans.xml
<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-2.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schema/jaxws.xsd"> <bean id="helloWorld" class="demo.spring.HelloWorld" factory-bean="clientFactory" factory-method="create"/> <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value="demo.spring.HelloWorld"/> <property name="address" value="http://localhost:8080/cxf2/HelloWorld"/> </bean> </beans>
