cxf环境搭建与第一个项目

1.什么是cxf

Cxf，apache下的webservice的开源框架。
Apache CXF = Celtix + Xfire，开始叫 Apache CeltiXfire，后来更名为 Apache CXF 了，以下简称为 CXF。Apache CXF 是一个开源的 web Services 框架，CXF 帮助您构建和开发 web Services ，它支持多种协议，比如：SOAP1.1,1,2、XML/HTTP、RESTful HTTP 或者 CORBA。
Cxf是基于SOA总线结构，依靠spring完成模块的集成，实现SOA方式。

2.环境配置

下载地址：
http://cxf.apache.org/download.html
环境变量 :
CXF_HOME=cxf的目录
PATH = PATH;CXF_HOME\bin;

3.第一个程序

• 在客户端和服务器端都要导入cxf的lib包

- 第一步写sei及其实现

@WebService(        targetNamespace="http://weather.itcast.cn/",//指定 wsdl的命名空间        name="WeatherInterface",//指定portType的名称        portName="WeatherInterfacePort",//指定port的名称        serviceName="WeatherService"//服务视图的名称        //endpointInterface="cn.itcast.ws.service.WeatherInterface2"//指定哪个接口中方法要发布成webservice服务，接口中加上@webservice注解        )@BindingType(javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING)public interface WeatherInterface {    //查询三天天气    public @WebResult(name="result") List<WeatherModel> queryWeather(@WebParam(name="cityName") String cityName);}

public class WeatherInterfaceImpl implements WeatherInterface {    @Override    public  List<WeatherModel> queryWeather(String cityName) {        //构造三天天气        List<WeatherModel> list = new ArrayList<WeatherModel>();        Calendar calendar = Calendar.getInstance();        int day = calendar.get(Calendar.DATE);        WeatherModel weatherModel_1  =new WeatherModel();        weatherModel_1.setDetail("晴");        weatherModel_1.setData(new Date());        weatherModel_1.setTemperature_max(5);        weatherModel_1.setTemperature_min(-6);        WeatherModel weatherModel_2  =new WeatherModel();        weatherModel_2.setDetail("阴");        calendar.set(Calendar.DATE, day+1);        weatherModel_2.setData(calendar.getTime());        weatherModel_2.setTemperature_max(10);        weatherModel_2.setTemperature_min(-3);        WeatherModel weatherModel_3  =new WeatherModel();        weatherModel_3.setDetail("晴");        calendar.set(Calendar.DATE, day+2);        weatherModel_3.setData(calendar.getTime());        weatherModel_3.setTemperature_max(2);        weatherModel_3.setTemperature_min(-9);        list.add(weatherModel_1);        list.add(weatherModel_2);        list.add(weatherModel_3);        return list;    }}

- 第二步：推送服务

public class WeatherServer {    public static void main(String[] args) {        //使用jaxWs发布soap协议的webservice        JaxWsServerFactoryBean jaxWsServerFactoryBean = new JaxWsServerFactoryBean();        //指定 webservice地址        jaxWsServerFactoryBean.setAddress("http://127.0.0.1:12345/weath");        //指定 porttype        jaxWsServerFactoryBean.setServiceClass(WeatherInterface.class);        //指定服务类对象        jaxWsServerFactoryBean.setServiceBean(new WeatherInterfaceImpl());        //发布服务        jaxWsServerFactoryBean.create();    }}

然后在浏览器中输入
http://127.0.0.1:12345/weath?wsdl就能看到说明文档

第三步 利用cxf工具自动生成调用服务的代码

wsdl2java -d xxx http://127.0.0.1:12345/weath?wsdl

• 第四步 编写客户端调用服务

package cn.itcast.weather;import java.util.Date;import java.text.SimpleDateFormat;import java.util.List;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;public class WeathClient3 {    public static void main(String[] args) {        JaxWsProxyFactoryBean jaxWsProxyFactoryBean=new JaxWsProxyFactoryBean();        jaxWsProxyFactoryBean.setAddress("http://127.0.0.1:12345/weath?wsdl");        jaxWsProxyFactoryBean.setServiceClass(WeatherInterface.class);        WeatherInterface weatherInterface = (WeatherInterface) jaxWsProxyFactoryBean                .create();        // 调用portType方法        List<WeatherModel> list = weatherInterface.queryWeather("郑州");        for (WeatherModel weatherModel : list) {            System.out.println(weatherModel.getDetail());            Date date = weatherModel.getData().toGregorianCalendar().getTime();            System.out.println(new SimpleDateFormat("yyyy-MM-dd").format(date));            System.out.println(weatherModel.getTemperatureMax());            System.out.println(weatherModel.getTemperatureMin());        }    }}

结果
