JAVA的WebService规范JAX-WS

JAX-WS的服务端、客户端双方传输数据使用的SOAP消息格式封装数据。

一、下载apache-cxf-3.1.4.zip。

二、编写服务端

1、编写一个Web Service用来传输参数的类

package com.ws.services.entity;

import java.util.Date;

import javax.xml.bind.annotation.XmlRootElement;
/**
 * 该类为Web Service中的参数、返回值类型，故需要使用JAXB注解告诉CXF如何在XML和Java Object之间处理，
 * 因为，SOAP消息格式包装的是一段XML代码，无论是服务器端，还是客户端，
 * 在接收到SOAP消息时，都需要将XML转化为Java Object，
 * 在发送SOAP消息时，需要将Java Object转化为XML。
 * */
@XmlRootElement(name = "People")
public class People {
    private Long id;
    private String name;
    private Date birthday;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }
}

2、编写Web Service接口

package com.ws.services;

import java.util.List;
import javax.jws.WebService;
import com.ws.services.entity.People;

@WebService
public interface PeopleService {

    public String add(People people);

    public String del(People people);

    public String modify(People people);

    public People getOne(Long id);

    public List<People> getList(String name);
}

4、实现Web Service

package com.ws.services;

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

import javax.jws.WebService;

import com.ws.services.entity.People;

@WebService(endpointInterface="com.ws.services.PeopleService")
public class PeopleServiceImpl implements PeopleService {

    @Override
    public String add(People people) {
        // TODO Auto-generated method stub
        System.out.println("ADD："+people.getId()+","+people.getName()+","+people.getBirthday());
        return "ADD SUCCESS";
    }

    @Override
    public String del(People people) {
        // TODO Auto-generated method stub
        System.out.println("DEL："+people.getId()+","+people.getName());
        return "DEL SUCCESS";
    }

    @Override
    public String modify(People people) {
        // TODO Auto-generated method stub
        System.out.println("MODIFY："+people.getId()+","+people.getName());
        return "MODIFY SUCCESS";
    }

    @Override
    public People getOne(Long id){
        // TODO Auto-generated method stubSystem.out.println("QRY BEGIN");
        People people=new People();
        people.setId(4L);
        people.setName("Name-004");
        people.setBirthday(new Date());
        return people;

    }
    @Override
    public List<People> getList(String name){
        // TODO Auto-generated method stub
        List<People> list=new ArrayList<People>();
        People people0=new People();
        People people1=new People();
        people0.setId(5L);
        people0.setName(name+"-005");
        people0.setBirthday(new Date());
        people1.setId(6L);
        people1.setName(name+"-006");
        people1.setBirthday(new Date());
        list.add(people0);
        list.add(people1);
        return list;
    }
}

5、发布Web Service服务

package com.ws.services;

import javax.xml.ws.Endpoint;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class SoapServer {
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        /**
         * 方法一，使用javax.xml.ws.*包中的EndPoint的静态方法publish()发布Web服务
         * */
        //Endpoint.publish("http://127.0.0.1:80/peopleService", new PeopleServiceImpl());

        /**
         * 方法二，使用CXF特有的API---JaxWsServerFactoryBean发布Web服务，
         * 并且我们对服务端工厂Bean的输入拦截器集合、输出拦截器集合中分别添加了日志拦截器，
         * 可以在Web服务端发送和接收消息时输出信息。
         */
        JaxWsServerFactoryBean soapFactoryBean = new JaxWsServerFactoryBean();
        soapFactoryBean.getInInterceptors().add(new LoggingInInterceptor());
        soapFactoryBean.getOutInterceptors().add(new LoggingOutInterceptor());
        // 注意这里是实现类不是接口
        soapFactoryBean.setServiceClass(PeopleServiceImpl.class);
        soapFactoryBean.setAddress("http://127.0.0.1:80/peopleService");
        soapFactoryBean.create();

        System.out.println("published...");
    }
}

6、测试服务发布情况

运行Java Application，访问http://127.0.0.1/peopleService?wsdl

三、编写客户端代码

1、使用WSDL2Java生成Web Service客户端代码

(1)配置CXF环境变量

path中加入apache-cxf-3.1.4\bin的绝对路径。

（2）使用WSDL2Java生成Web Service客户端代码，命令如下：

wsdl2java -p com.ws.client -d D:\\src -client http://127.0.0.1/peopleService?wsdl

将生成的类拷入Web Service客户端工程中。

2、编写客户端测试方法

package com.ws;

import java.net.MalformedURLException;
import java.net.URL;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.GregorianCalendar;
import java.util.List;

import javax.xml.namespace.QName;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import com.sun.org.apache.xerces.internal.jaxp.datatype.XMLGregorianCalendarImpl;
import com.ws.client.People;
import com.ws.client.PeopleService;
import com.ws.client.PeopleServiceImplService;

public class SoapClient {

    public static void main(String[] args) throws ParseException, MalformedURLException {
        // TODO Auto-generated method stub
        /**
         * 使用准的JAX-WS的API完成客户端调用
         * */
        //使用Web服务的WSDL中的targetNamespace和<wsdl:service …中的name属性构建了javax.xml.namespace.QName接口
        QName qName = new QName("http://services.ws.com/", "PeopleServiceImplService");
        PeopleServiceImplService peopleServiceImplService = new PeopleServiceImplService(new URL("http://127.0.0.1/peopleService?wsdl"), qName);
        PeopleService ps = (PeopleService) peopleServiceImplService.getPort(PeopleService.class);

        /**
         * 使用CXF 的JaxWsProxyFactoryBean来完成客户端调用
         * */
        /*JaxWsProxyFactoryBean soapFactoryBean = new JaxWsProxyFactoryBean();
        soapFactoryBean.setAddress("http://127.0.0.1:80/peopleService");
        soapFactoryBean.setServiceClass(PeopleService.class);
        Object o = soapFactoryBean.create();
        PeopleService ps = (PeopleService) o;*/

        People p1 = new People();
        p1.setId(1L);
        p1.setName("陈一");
        GregorianCalendar calendar = (GregorianCalendar) GregorianCalendar.getInstance();
        calendar.setTime(new SimpleDateFormat("yyyy-MM-dd").parse("1989-01-28"));
        p1.setBirthday(new XMLGregorianCalendarImpl(calendar));
        ps.add(p1);

        People p4 = ps.getOne(4L);
        System.out.println("4：" + p4.getId() + "," + p4.getName() + "," + p4.getBirthday());

        List<People> p5 = ps.getList("王五");
        for (People p : p5) {
            System.out.println("5：" + p.getId() + "," + p.getName() + "," + p.getBirthday());
        }
    }

}

最后，进行测试。

备注：

webservice服务端启动时，报错：prefix wsdp is not bound to a namespace，去掉下列四个jar包，

cxf-services-ws-discovery-api-3.1.4.jar

cxf-services-ws-discovery-service-3.1.4.jar

cxf-services-wsn-api-3.1.4.jar

cxf-services-wsn-core-3.1.4.jar
