CXF和spring整合实现webservice实例
环境:JDK6.0,cxf-2.0.7,spring2.5,tomcat6.0
服务器端:
1.新建Web项目,例如webws,导入cxf-2.0.7/lib下的jar包和spring2.5的包,因为cxf支持spring,因此它自带有sping的一些核心包,为了以后扩展,保险起见都一起导入吧。。
2.新建一个服务接口IHelloWorld.java,该接口是面向客户端,暴露服务:
package cn.com.service;import javax.jws.WebParam;import javax.jws.WebService;@WebServicepublic interface IHelloWorld { //@WebParam(name="arg0")可有可无,为了增强可读性public String sayHello(@WebParam(name="arg0")String text);}3.再新建该接口的实现类HelloWorldImpl.java:
package cn.com.service;import javax.jws.WebService;@WebService(endpointInterface="cn.com.service.IHelloWorld")public class HelloWorldImpl implements IHelloWorld {public String sayHello(String text) {return "Hello" + text ;}}4.现在可以进行spring配置了,在eclipse的src文件夹下新建applicationContext.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:p="http://www.springframework.org/schema/p"xmlns:jaxws="http://cxf.apache.org/jaxws"xmlns:cxf="http://cxf.apache.org/core"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.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="hello" implementor="#hello" address="/HelloWorld" /></beans>
注意:1).<beans>元素里面的命名空间一定要正确,特别要增加xmlns:jaxws="http://cxf.apache.org/jaxws",http://cxf.apache.org/jaxws,http://cxf.apache.org/schemas/jaxws.xsd;
2).cxf.xml,cxf-extension-soap.xml,cxf-servlet.xml三个文件都在cxf-2.0.7.jar中把它们拷贝到META-INF/目录下。
5.配置web.xml:
<?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"><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><servlet><servlet-name>CXFServlet</servlet-name><display-name>CXF Servlet</display-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><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>
到此服务器端基本上告一段落,可以将应用部署到tomcat,启动并访问http://localhost:8080/webws/HelloWorld?wsdl,如果能正确显示xml文件则说明部署成功。
客户端:
1.新建一个java项目,例如wsclient,也导入cxf-2.0.7和spring包
2.新建客户程序(如果熟悉cxf可以运用cxf的wsdl2java命令直接根据wsdl生成),如Test.java:
package pro.webws.client;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test {public static void main(String[] args) {ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-client.xml");IHelloWorld client = (IHelloWorld) ctx.getBean("client");String result = client.sayHello("你好!");System.out.println(result);}}根据代码,我们知道还需要新建一个IHelloWorld接口,这是服务器端暴露的服务,我们还需要在客户端再新建一个以利用之,代码和服务器端一致即可,不再赘述。
现在可以配置客户端的spring文件了,新建spring-client.xml文件:
<?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:p="http://www.springframework.org/schema/p"xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:cxf="http://cxf.apache.org/core"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsdhttp://cxf.apache.org/jaxws http://cxf.apache.org/schema/jaxws.xsd"><bean id="client" factory-bean="clientFactory"factory-method="create" /><bean id="clientFactory" value="pro.webws.client.IHelloWorld" /><property name="address" value="http://localhost:8080/webws/HelloWorld" /></bean></beans>
注意:<property name="address" value="http://localhost:8080/webws/HelloWorld" />中的/HelloWorld要与服务器端applicationContext.xml中的<jaxws:endpoint id="helloWorld" implementor="#hello" address="/HelloWorld" />的address属性对应。
现在服务器和客户端都已完成,启动tomcat,运行客户程序,将输出结果:
Hello你好!
at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:192)
at $Proxy16.sayHello(Unknown Source) 4 楼 liuxueping1987 2012-04-20 按照你的步骤做,服务端没有问题,但是客户端在运行,调用服务时报下面的错误,求指导。。多谢!! 5 楼 liuxueping1987 2012-04-20 已经解决时项目的大小写问题,弄了半天才解决。。。
刚开始我的项目名为SpringAndCXFService 改为 springAndCXFService就ok拉 6 楼 dobuy 2012-07-06 谢谢啊啊啊
