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());
        }
    }
}
