webservice之CXF注解实现（一）

1.关于CXF(摘自百度百科)

Apache CXF = Celtix + XFire，开始叫 Apache CeltiXfire，后来更名为 Apache CXF 了，以下简称为 CXF。CXF 继承了 Celtix 和 XFire 两大开源项目的精华，提供了对 JAX-WS 全面的支持，并且提供了多种 Binding 、DataBinding、Transport 以及各种 Format 的支持，并且可以根据实际项目的需要，采用代码优先（Code First）或者 WSDL 优先（WSDL First）来轻松地实现 Web Services 的发布和使用。Apache CXF已经是一个正式的Apache顶级项目。
Apache CXF 是一个开源的 Services 框架，CXF 帮助您利用 Frontend 编程 API 来构建和开发 Services ，像 JAX-WS 。这些 Services 可以支持多种协议，比如：SOAP、XML/HTTP、RESTful HTTP 或者 CORBA ，并且可以在多种传输协议上运行，比如：HTTP、JMS 或者 JBI，CXF 大大简化了 Services 的创建，同时它继承了 XFire 传统，一样可以天然地和 Spring 进行无缝集成。

2.下载

http://cxf.apache.org/download.html

3.集成到eclipse

笔者下载的版本是2.7.7，进入apache-cxf-2.7.7/lib目录，将所需jar包复制到工程中，需要的jar包较多，如图：

4.web.xml

                <bean class="com.look.service.IServiceImpl" />
       </jaxws:serviceBean>
   </jaxws:server>
</beans>

6.IService.java

package com.look.service;

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

import com.protal.model.RequestCondition;

@WebService
public interface IService
{
    @WebMethod
    String test(@WebParam  RequestCondition requestCondition);
 }

7.IServiceImpl.java

package com.look.service;

import com.protal.model.RequestCondition;

public class IServiceImpl implements IService
{
    @Override
    public String test(RequestCondition requestCondition)
    {
       return “年龄是：”+requestCondition.getAge();
    }
}

8.部署并测试

将项目部署到web服务器，如tomcat

编写测试类

package com.look.utest;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import com.look.service.IService;
import com.protal.model.RequestCondition;

public class Test {
	public static void main(String[] args) {
		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();  
	    factory.getInInterceptors().add(new LoggingInInterceptor());  
	    factory.getOutInterceptors().add(new LoggingOutInterceptor());  
	    factory.setServiceClass(IService.class);  
	    factory.setAddress("http://localhost:8080/PortalService/services/test");  
	    IService client = (IService) factory.create();
	    RequestCondition requestCondition = new RequestCondition();
	    requestCondition.setAge("18");
	    String msg =  client.test(requestCondition);
	    System.out.println(msg);
	}
}
