Apache CXF WebService教程-优快云博客

本文介绍Apache CXF，一种基于最新WebService标准JAX-WS的开源框架。CXF支持多种协议，如SOAP、XML/HTTP及CORBA，并能与Spring无缝整合。文章详细讲解CXF的安装配置过程及如何通过示例项目实现WebService服务。

什么是CXF?
Apache CXF=Celtix+XFire
jax-ws是Sun公司发布的一套开发WebService服务的标准,CXF是在新标准ax-ws下开发出来的WebService.
支持多种协议：
SOAP
XML/HTTP
CORBA(Commom Object Request Broker Architecture公共对象请求代理体系结构，早期语言使用的WS)
可以与Spring进行快速无缝的整合
灵活的部署：可以运行有Tomcat,Jboss,Jetty(内置),IBMWS,BeaWs上面

CXF的安装和配置
1、我的版本是apache-cxf-2.4.0,下载完成后将其解压到某个目录下【注：目录名字尽量不要有中文】
2、安装CXF的其他支持项目：ant   和   Tomcat
3、安装完成后设置环境变量：
CXF_HOME: D:\Ncode\cxf\apache-cxf-2.4.0\apache-cxf-2.4.0\samples\java_first_pojo
ANT_HOME: D:\Ncode\cxf\apache-cxf-2.4.0\apache-cxf-2.4.0\samples\java_first_pojo
Path = D:\Ncode\cxf\apache-cxf-2.4.0\apache-cxf-2.4.0\samples\java_first_pojo; D:\Ncode\cxf\apache-cxf-2.4.0\apache-cxf-2.4.0\samples\java_first_pojo
CLASSPATH=.;%CXF_HOME%\lib\cxf-manifest.jar;.\build\classes
在dos命令中使用命令测试是否成功
     C:\Documents and Settings\Administrator>ant
	Buildfile: build.xml does not exist!
	Build failed
     C:\Documents and Settings\Administrator>wsdl2java
	Missing argument: wsdlurl
如果你显示的和上面一样，说明你已经配置成功啦
用ant来构造第一个CXF示例：
切换到实例目录：   
	C:\Documents and Settings\Administrator>d:  
	D:\>cd D:\Ncode\cxf\apache-cxf-2.4.0\samples\java_first_pojo //切换目录
	D:\Ncode\cxf\apache-cxf-2.4.0\samples\java_first_pojo>ant  //执行ant操作
		Buildfile: D:\Ncode\cxf\apache-cxf-2.4.0\samples\java_first_pojo\build.xml
    		[mkdir] Created dir: D:\Ncode\cxf\apache-cxf-2.4.0\samples\java_first_pojo\build
 		[loadfile] Do not set property srcbuild.classpath as its length is 0.
		BUILD FAILED

启动服务：

打开新的界面执行客户端操作：
    D:\Ncode\cxf\apache-cxf-2.4.0\samples\java_first_pojo>ant client
	Buildfile: D:\Ncode\cxf\apache-cxf-2.4.0\samples\java_first_pojo\build.xml

	false for repeatable builds
 	[loadfile] Do not set property srcbuild.classpath as its length is 0.
	copy.maven.resources:
	build:
	client:
    	 [java] Invoke sayHi()....
     	[java] Hello redarmychen
	BUILD SUCCESSFUL
	Total time: 3 seconds

用ant将它发布到Tomcat服务器上：
1、	执行ant clean方法清除以前生成的代码
2、	执行ant war打包此应用
3、	执行ant deplay-Dtomcat=true将项目发布到tomcat的服务器上
4、	启动tomcat服务器
5、	打开IE的地址输入栏输入：http://localhost:9999/helloworld/services/hello_world?wsdl
或：http://localhost:9999/helloworld/services
6、	在命令行中执行：
ant client-servlet –Dbase.url=http://localhost:9999
或在MyEclipse的WebServiceExplorer中访问这个WebService
7、	停止tomcat服务器
8、	卸载应用：ant undeploy –Dtomcat=true
9、	清空项目：ant clean
注:ant war,在build中会有一个war文件，把这个文件放到tomcat/webapps下，直接打开tomcat就启动成功了
