发布Web服务和调用Web服务

1.jdk版本至少要的1.6.0_.04

2.jdk的环境变量已经配置好的

　　1.JAVA_HOEM    JDK文件夹的地址      例: E:javajdk
　　2.PATH    jdk文件夹下bin目录的地址;jdk文件夹下lib目录的地址    例:E:javajdkin;E:javajdklib  或  %JAVA_HOEM%in;%JAVA_HOEM%lib
　　3.CLASSPATH   .;+jdk文件夹下lib目录的地址;jdk文件夹下jre文件夹lib目录的地址   例:  .;E:javajdklib;E:javajdkjrelib  或  .;%JAVA_HOEM%lib;%JAVA_HOEM%jrelib

3.发布web服务示例如下:

　　1.定义接口,使用@WebService()注解作为一个web服务

package cn.bd.weather.service;

import java.util.Date;
import java.util.List;

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

import cn.bd.weather.entity.Weather;

@WebService()
public interface WeatherService {
    @WebMethod
    List<Weather> getWeathers(String city,List<Date> dates);
17 }

　　2.编写web服务接口的实现 类

package cn.bd.weather.service.impl;

import java.util.ArrayList;
import java.util.Date;

import java.util.List;

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

import cn.bd.weather.entity.Weather;
import cn.bd.weather.service.WeatherService;

@WebService
public class WeatherServiceImpl implements WeatherService {
    
    @WebMethod
    public List<Weather> getWeathers(String city, List<Date> dates) {
        List<Weather> list=new ArrayList<Weather>();
        for(Date date : dates){
            list.add(getWeather(city,date));
        }
        return list;
    }
    
    @WebMethod
    public Weather getWeather(String city,Date date){
        return new Weather(city,date,25,27,30,"晴");
    }

}

　　3.发布web服务的测试

package cn.bd.weather.test;

import javax.xml.ws.Endpoint;

import cn.bd.weather.service.impl.WeatherServiceImpl;

public class Service {
    
    protected Service(){
        System.out.println("启动");
        WeatherServiceImpl weatherServiceImpl=new WeatherServiceImpl();
        String address="http://localhost:10086/weatherservice";//对外发布的接口
        Endpoint.publish(address, weatherServiceImpl);//接口发布
    }
    
    public static void main(String[] args) throws Exception {
        new Service();
        System.out.println("服务准备.........");
        Thread.sleep(5*60*1000);
        System.out.println("服务关闭.........");
        System.exit(0);//关闭服务 
    }
}

运行程序,在浏览器输入:http://localhost:10086/weatherservice?wsdl,出现xml文件表示发布成功.

调用web服务

1.在控制台输入 wsimport -s data http://localhost:10086/weatherservice?wsdl,其中data是已经建好的文件夹,data后面的发布的地址

2.将会在data文件夹生成java类,如图所示

3.将Weather.java和WeatherService.java复制到程序

4.编写客户端代码

package cn.bd.weather.client;
import java.net.MalformedURLException;
import java.net.URL;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;

public class Client {
        //指定服务名
        private static final QName SERVICE_NAME = new QName(
                "http://impl.service.weather.bd.cn/", "WeatherServiceImplService");
        //指定端口名
        private static final QName PORT_NAME = new QName(
                "http://impl.service.weather.bd.cn/", "WeatherServiceImplPort");
        //指定位置
        private static final String  WSDL_LOCATION = "http://localhost:10086/weatherservice?wsdl";
        
        public static void main(String[] args) throws ParseException, MalformedURLException {
            //根据服务器地址创建URL对象
            URL wsdlUrl=new URL(WSDL_LOCATION);
            //根据URL对象和服务器名称创建Service类
            Service service=Service.create(wsdlUrl, SERVICE_NAME);
            //获取服务实现类
            WeatherServiceImpl port=service.getPort(PORT_NAME, WeatherServiceImpl.class);
            List<Date> dates=new ArrayList<Date>();
            DateFormat format=new SimpleDateFormat("yyyy-MM-dd");
            Date date1=format.parse("2016-12-1");
            Date date2=format.parse("2016-12-2");
            Date date3=format.parse("2016-12-3");
            dates.add(date1);
            dates.add(date2);
            dates.add(date3);
            //调用服务
            List<Weather> obj=port.getWeathers("beijing", dates);
            for (Weather weather : obj) {
                System.out.println(weather.getCity()+"	"
                        +format.format(weather.getDate())+"	"
                        +weather.getMax()+"	"
                        +weather.getMin()+"	"
                        +weather.getAverage()+"	"
                        +weather.getDesc());
                System.out.println("
");
            }
        }
    }
