CXF实现WebService

首先下载cxf包，目前最新的版本是apache-cxf-2.1.，下栽地址http://cxf.apache.org/download.html。

1. 首先新建一个web工程CxfService，导入cxf所需要的包。要导入的包如下：

commons-logging-1.1.jar
geronimo-activation_1.1_spec-1.0-M1.jar (or Sun's Activation jar)
geronimo-annotation_1.0_spec-1.1.jar (JSR 250)
geronimo-javamail_1.4_spec-1.0-M1.jar (or Sun's JavaMail jar)
geronimo-servlet_2.5_spec-1.1-M1.jar (or Sun's Servlet jar)
geronimo-ws-metadata_2.0_spec-1.1.1.jar (JSR 181)
jaxb-api-2.1.jar
jaxb-impl-2.1.6.jar
jaxws-api-2.1.jar
jetty-6.1.5.jar
jetty-util-6.1.5.jar
neethi-2.0.jar
saaj-api-1.3.jar
saaj-impl-1.3.jar
stax-api-1.0.1.jar
wsdl4j-1.6.1.jar
wstx-asl-3.2.1.jar
XmlSchema-1.2.jar
xml-resolver-1.2.jar

The Spring jars (optional - for XML Configuration support):

aopalliance-1.0.jar
spring-core-2.0.4.jar
spring-beans-2.0.4.jar
spring-context-2.0.4.jar
spring-web-2.0.4.jar

And the CXF jar:

cxf-2.1.jar

2.新建一个接口类：HelloWorld，如下：

Java代码

1. package com.zx.cxf.service;  

2. import javax.jws.WebParam;  

3. import javax.jws.WebService;  

4. @WebService

5. publicinterface HelloWorld {  

6.  String sayHi(@WebParam(name="text") String text);  

7. }

package com.zx.cxf.service;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface HelloWorld {
    String sayHi(@WebParam(name="text") String text);
}

创建接口的实现类：HelloWorldImpl，如下

Java代码

1. package com.zx.cxf.service;  

2. import javax.jws.WebService;  

3. import com.zx.cxf.service.HelloWorld;  

4. @WebService(endpointInterface = "com.zx.cxf.service.HelloWorld",  

5.      serviceName = "HelloWorld")  

6. publicclass HelloWorldImpl implements HelloWorld {  

7. public String sayHi(String text) {  

8. return"Hello " + text;  

9.  }  

10. }

package com.zx.cxf.service;

import javax.jws.WebService;

import com.zx.cxf.service.HelloWorld;
@WebService(endpointInterface = "com.zx.cxf.service.HelloWorld", 
            serviceName = "HelloWorld")
public class HelloWorldImpl implements HelloWorld {
 
    public String sayHi(String text) {
        return "Hello " + text;
    }
}

*@WebService：申明为webservice的注解

*endpointInterface：要暴露的接口类

*serviceName ：  服务名

在WEB-INF目录下新建beans.xml，如下：

Xml代码

1. <?xmlversion="1.0"encoding="UTF-8"?>

2. <!-- START SNIPPET: beans -->

3. <beansxmlns="http://www.springframework.org/schema/beans"

4. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

5. xmlns:jaxws="http://cxf.apache.org/jaxws"

6. xsi:schemaLocation="  

7. http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  

8. http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

9. <importresource="classpath:META-INF/cxf/cxf.xml"/>

10. <importresource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>

11. <importresource="classpath:META-INF/cxf/cxf-servlet.xml"/>

12. <jaxws:endpoint

13. id="helloWorld"

14. implementor="com.zx.cxf.service.HelloWorldImpl"

15. address="/HelloWorld"/>

16. </beans>

17. <!-- END SNIPPET: beans -->

<?xml version="1.0" encoding="UTF-8"?>

<!-- START SNIPPET: beans -->
<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" />

	<jaxws:endpoint 
	  id="helloWorld" 
	  implementor="com.zx.cxf.service.HelloWorldImpl" 
	  address="/HelloWorld" />
	  
</beans>
<!-- END SNIPPET: beans -->

注： implementor ：接口类的实现类

   address：  要和注释里面神秘的服务名对应，

修改web.xml文件，如下：

Xml代码

1. <?xmlversion="1.0"encoding="ISO-8859-1"?>

2. <!DOCTYPE web-app  

3.  PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"  

4.  "http://java.sun.com/dtd/web-app_2_3.dtd">

5. <!-- START SNIPPET: webxml -->

6. <web-app>

7. <context-param>

8. <param-name>contextConfigLocation</param-name>

9. <param-value>/WEB-INF/beans.xml</param-value>

10. </context-param>

11. <listener>

12. <listener-class>

13.      org.springframework.web.context.ContextLoaderListener  

14. </listener-class>

15. </listener>

16. <servlet>

17. <servlet-name>CXFServlet</servlet-name>

18. <display-name>CXF Servlet</display-name>

19. <servlet-class>

20.      org.apache.cxf.transport.servlet.CXFServlet  

21. </servlet-class>

22. <load-on-startup>1</load-on-startup>

23. </servlet>

24. <servlet-mapping>

25. <servlet-name>CXFServlet</servlet-name>

26. <url-pattern>/services/*</url-pattern>

27. </servlet-mapping>

28. </web-app>

29. <!-- END SNIPPET: webxml -->

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

<!-- START SNIPPET: webxml -->

	<context-param>

	</context-param>

	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

	<servlet>
		<servlet-name>CXFServlet</servlet-name>

</web-app>
<!-- END SNIPPET: webxml -->

启动tomcat

测试：简单的测试就是ie测试，在浏览器中输入http://localhost:8080/CxfService/services/，如果出现

{http://service.cxf.zx.com/}HelloWorldImplPort ，或者输入http://localhost:8080/CxfService/services/HelloWorld?wsdl，出现wsdl文挡，则说明服务器端配置成功。

可户端测试：

测试类如下：

Java代码

1. package com.zx.cxf.service;  

2. import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;  

3. import org.apache.cxf.interceptor.*;  

4. import com.zx.cxf.service.HelloWorld;  

5. publicclass client {  

6. private client() {  

7.  }  

8. publicstaticvoid main(String args[]) throws Exception {  

9.    JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();  

10.    factory.getInInterceptors().add(new LoggingInInterceptor());  

11.    factory.getOutInterceptors().add(new LoggingOutInterceptor());  

12.    factory.setServiceClass(HelloWorld.class);  

13.    factory.setAddress("http://localhost:8080/CxfService/services/HelloWorld");  

14.    HelloWorld client = (HelloWorld) factory.create();  

15.    String reply = client.sayHi("HI");  

16.    System.out.println("Server said: " + reply);  

17.  }  

18. }

package com.zx.cxf.service;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.apache.cxf.interceptor.*;
import com.zx.cxf.service.HelloWorld;
public  class client {

   

    private client() {
    } 

    public static void main(String args[]) throws Exception {
    	JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
    	factory.getInInterceptors().add(new LoggingInInterceptor());
    	factory.getOutInterceptors().add(new LoggingOutInterceptor());
    	factory.setServiceClass(HelloWorld.class);
    	factory.setAddress("http://localhost:8080/CxfService/services/HelloWorld");
    	HelloWorld client = (HelloWorld) factory.create();

    	String reply = client.sayHi("HI");
    	System.out.println("Server said: " + reply);
    }

}

如果控制台打印出：Server said: Hello HI则说明测试成功。

Ps:如果出现in thread "main" javax.xml.ws.soap.SOAPFaultException: Error reading XMLStreamReader.

关掉防火墙就可以了。
