《转》利用cxf实现webservice

2013-08-19 14:11 316 查看
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:

Java代码


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


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


<?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


<?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:

Java代码


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@WebMethodWSDL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。
@WebServiceannotation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.
@WebMethodAnnotation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.
@WebResultAnnotation的partName成员描述了wsdl:part用来返回WSDL文档的值。
