《转》利用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，倒入cxf所学要的包。要倒入的包如下：

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：

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

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 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 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 -->
<web-app>
    <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>
        <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>/services/*</url-pattern>
    </servlet-mapping>
</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：

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。

下面是源文件：下载后倒入所需要的包

• CxfService.rar (5.5 KB)

@WebService和@WebMethod	是WSDL映射Annotation.这些Annotation将描述Web Service的WSDL文档元素和JAVA源代码联系在一起。
@WebService和@WebMethod	WSDL映射Annotation.这些Annotation将描述Web Service的WSDL文档元素和JAVA源代码联系在一起。
@WebService	annotation的元素name,serviceName和targetNamespace成员用来描述wsdl:protType,wsdl:service,和targetNameSpace生成WebService中的WSDL文件。
@SOAPBinding	是一个用来描述SOAP格式和RPC的协议的绑定Annotation.
@WebMethod	Annotation的operationName成员描述了wsdl:operation,而且它的操作描述了WSDL文件中的SOAPAction头部，这是客户端必须要放入到SOAPHeader中的数值，SOAP1.1中的一种约束。
@WebParam	是一个用来描述SOAP格式和RPC的协议的绑定Annotation.
@WebResult	Annotation的partName成员描述了wsdl:part用来返回WSDL文档的值。
