我们先来了解一下WebService吧：
新建一个WebService的工程，并把JBoss下client中的包全部引入进去，然后创建一个JavaBean、Service接口和Service实现类，如下：
package com.zlb.bean;
import java.io.Serializable;
public class Order implements Serializable{
/**
*
*/
private static final long serialVersionUID = -6775239525080104316L;
private String orderid;
private String name;
public String getOrderid() {
return orderid;
}
public void setOrderid(String orderid) {
this.orderid = orderid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
package com.zlb.service;
import java.util.List;
import com.zlb.bean.Order;
public interface OrderService {
public String getUserName(String name);
public Order getOrder(String orderid);
public List<Order> getOrders();
}
package com.zlb.service.impl;
import java.util.ArrayList;
import java.util.List;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.jws.WebService;
import com.zlb.bean.Order;
import com.zlb.service.OrderService;
//修改命名空间的名称、接口的名称以及服务的名称
@WebService(targetNamespace="http://ws.zlb.com",
name="OrderService",
serviceName="OrderServiceBean")
@Stateless
@Remote(OrderService.class)
public class OrderServiceBean implements OrderService {
public String getUserName(String name) {
return name;
}
public Order getOrder(String orderid) {
Order order = new Order();
order.setOrderid(orderid);
order.setName("小明");
return order;
}
public List<Order> getOrders() {
List<Order> persons = new ArrayList<Order>();
Order order1 = new Order();
order1.setOrderid("1");
order1.setName("小丽");
Order order2 = new Order();
order2.setOrderid("2");
order2.setName("小琴");
persons.add(order1);
persons.add(order2);
return persons;
}
}
在实现类中，如果只是想暴露某个方法，则可以在方法上面加@WebMethod。如果想修改图三中的三个红框中的值可以按照实现类中@WebSerivce注解的格式写。
接着，可以通过ANT编译一下，有关代码请参考：http://blog.csdn.net/zlb824/article/details/7067113
编译完之后你可以在后台进行查看，输入URL：http://localhost:8080/jbossws/，如下：
接下来我们要开始编写客户端代码啦，先来张图片了解一下吧：
因此，我们可以通过ANT来生成客户端辅助类，相关代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<project name="webServiceClient" default="zlb" basedir=".">
<property name="src.dir" value="${basedir}/src"/>
<path id="build.classpath" description="设置类路径">
<fileset dir="${basedir}/lib">
<include name="*.jar"/>
</fileset>
</path>
<target name="zlb" description="生成webservice客户端辅助代码，执行后请刷新项目">
<taskdef name="wsimport" classname="com.sun.tools.ws.ant.WsImport" classpathref="build.classpath"/>
<wsimport wsdl="http://127.0.0.1:8080/webService/OrderServiceBean?wsdl"
sourcedestdir="${src.dir}" package="com.zlb.client" keep="true"
verbose="true" destdir="${basedir}/bin"/>
<!-- keep的值代表是否更新旧值,varbose的值代表是否打印操作过程,destdir的值代表源文件编译过后存放的路径 -->
</target>
</project>
有这个配置中的工程名可以看出，我们要新建一个客户端工程，然后我们可以再新建一个JUnit测试类，如下：
package com.zlb.junit;
import java.util.List;
import org.junit.BeforeClass;
import org.junit.Test;
import com.zlb.client.Order;
import com.zlb.client.OrderService;
import com.zlb.client.OrderServiceBean;
public class JunitWS {
@BeforeClass
public static void setUpBeforeClass() throws Exception {
}
@Test
public void getUserName() {
OrderServiceBean osb = new OrderServiceBean();//创建一个服务对象
OrderService orderService = osb.getOrderServicePort();//通过服务对象得到端点
System.out.println(orderService.getUserName("小明"));
}
@Test
public void getOrder(){
OrderServiceBean osb = new OrderServiceBean();//创建一个服务对象
OrderService orderService = osb.getOrderServicePort();//通过服务对象得到端点
Order order = orderService.getOrder("111");
System.out.println(order.getOrderid()+","+order.getName());
}
@Test
public void getOrders(){
OrderServiceBean osb = new OrderServiceBean();//创建一个服务对象
OrderService orderService = osb.getOrderServicePort();//通过服务对象得到端点
List<Order> orders = orderService.getOrders();
for(Order order : orders)
System.out.println(order.getOrderid()+","+order.getName());
}
}
得出的结果分别如下：
小明
111，小明
1,小丽
2,小琴
大功告成啦！可是别高兴太早，先来看看我的环境吧：
JDK：1.5
JBoss：4.2.2
可是，如果你换成下面两种情况的话就会报错啦，我们先来测试
JDK：1.5
JBoss：5.X
的情况吧，通过JUnit单元测试打印的结果如下：
第一个为：null
之后两个就是报错，截取一段吧，如下：

找不半天都不知道原因何在，如果有知道的童鞋还望分享一下。
再来看看
JDK：1.6
JBoss：5.X
不知道是不是我配置有问题，因为，看上面的文档说，JDK6的话不用把包全部引入进去，只需替换几个进行，都是，之后那个ANT配置文件我就不知道怎么写啦，因此，还是用了JDK5那个方法，有知道的童鞋麻烦告诉我一下，谢谢啦！
