1. 实例说明

现在大多数的网站都有通知功能（例如，放假通知，网站维护通知等），本实例就是针对于通知，发布两个WebService服务

1）根据供应商编号，状态，发布日期查询通知信息

2）根据编号查询通知信息

特别是需要注意的是本实例用到的axis2的版本为1.6.2，JDK版本为1.6

2. JAX-WS常用注解

javax.jws.WebService

@WebService 注释标记Java 类为标记服务端点接口（SEI） --targetNamespace，指定从 Web Service 生成的 WSDL 和 XML 元素的 XML 名称空间。缺省值为从包含该 Web Service 的包名映射的名称空间。（字符串）

javax.jws.WebMethod

@WebMethod 注释表示作为一项 Web Service 操作的方法。 --action，定义此操作的行为。对于 SOAP 绑定，此值将确定 SOAPAction 头的值。缺省值为 Java 方法的名称。（字符串）

javax.jws.WebParam

@WebParam 注释用于定制从单个参数至 Web Service 消息部件和 XML 元素的映射。

javax.jws.WebResult

@WebResult 注释用于定制从返回值至 WSDL 部件或 XML 元素的映射。将此注释应用于客户机或服务器服务端点接口（SEI）上的方法，或者应用于 JavaBeans 端点的服务器端点实现类。

3. 创建WebService服务

1）根据面向接口编程的原则，先创建一个Notice接口

 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 demo.axis2.jaxws.model.Notice;

 @WebService(targetNamespace = "http://core.jaxws.axis2.demo/notice")

 public interface NoticeBusiness {

     /**

      * 根据编号查询通知信息

      *

      * @param noticeId

      * @return

      */

     @WebMethod(action = "getByNoticeId")

     @WebResult(name = "notice")

     Notice getByNoticeId(@WebParam(name = "informationId") Integer noticeId);

     /**

      * 根据供应商编号，状态，发布日期查询通知信息

      *

      * @param supId

      * @param status

      * @param releaseTime

      * @return

      */

     @WebMethod(action = "queryNotices")

     @WebResult(name = "notices")

     List<Notice> queryNotices(@WebParam(name = "supId") Integer supId,

             @WebParam(name = "status") Integer status,

             @WebParam(name = "releaseTime") Date releaseTime);

 }

2）创建通知接口的实现类

 import java.util.ArrayList;

 import java.util.Collection;

 import java.util.Date;

 import java.util.List;

 import javax.jws.WebService;

 import demo.axis2.jaxws.core.NoticeBusiness;

 import demo.axis2.jaxws.dao.NoticeDAO;

 import demo.axis2.jaxws.model.Notice;

 @WebService(endpointInterface = "demo.axis2.jaxws.core.NoticeBusiness", serviceName = "Notice")

 public class NoticeBusinessImpl implements NoticeBusiness {

     @Override

     public Notice getByNoticeId(Integer noticeId) {

         Notice notice = NoticeDAO.instance.getModel().get(noticeId);

         if (notice == null)

             throw new RuntimeException("Notice with " + noticeId + " not found");

         return notice;

     }

     @Override

     public List<Notice> queryNotices(Integer supId, Integer status, Date releaseTime) {

         List<Notice> noticeList = new ArrayList<Notice>();

         Collection<Notice> notices = NoticeDAO.instance.getModel().values();

         for (Notice notice : notices) {

             if (notice.getSupId().intValue() == supId.intValue()

                     && notice.getStatus().intValue() == status.intValue()

                     && notice.getReleaseTime().after(releaseTime)) {

                 noticeList.add(notice);

             }

         }

         if (noticeList.size() == 0)

             throw new RuntimeException("Notice not found");

         return noticeList;

     }

 }

3）辅助类NoticeDAO，此类为枚举类型，用于提供测试数据

 import java.util.Date;

 import java.util.HashMap;

 import java.util.Map;

 import demo.axis2.jaxws.model.Notice;

 public enum NoticeDAO {

     instance;

     private Map<Integer, Notice> notices = new HashMap<Integer, Notice>();

     private NoticeDAO() {

         notices.put(1, new Notice(1, 10000, "51 holiday notice", "Fifty-one will leave three days",

                 "/images/20120701101010111.jpg", Constants.NOTICE_STATUS_RELEASED, "admin",

                 new Date()));

         notices.put(2, new Notice(2, 10000, "Mid notice",

                 "Mid-Autumn Festival , National Day holiday 8 days",

                 "/images/20120701101010222.jpg", Constants.NOTICE_STATUS_RELEASED, "admin",

                 new Date()));

     }

     public Map<Integer, Notice> getModel() {

         return notices;

     }

 }

4）实体类，由于篇幅的原因，代码未给数setter，getter方法

 public class Notice implements Serializable {

     private static final long serialVersionUID = 1L;

     private Integer noticeId;

     private Integer supId;

     private String title;

     private String content;

     private String attachment;

     private Integer status;

     protected String releaseUser;

     protected Date releaseTime;

     public Notice() {

     }

     public Notice(Integer noticeId, Integer supId, String title, String content, String attachment,

             Integer status, String releaseUser, Date releaseTime) {

         super();

         this.noticeId = noticeId;

         this.supId = supId;

         this.title = title;

         this.content = content;

         this.attachment = attachment;

         this.status = status;

         this.releaseUser = releaseUser;

         this.releaseTime = releaseTime;

     }

 }

5）常量类

public class Constants {

    /** 通知状态 */

    public static final int NOTICE_STATUS_COMMITED = 0;// 已提交

    public static final int NOTICE_STATUS_RELEASED = 1;// 已发布

}

6）修改web.xml文件，增加如下内容

 <servlet>

     <servlet-name>AxisServlet</servlet-name>

     <display-name>Apache-Axis Servlet</display-name>

     <servlet-class>

         org.apache.axis2.transport.http.AxisServlet</servlet-class>

     <load-on-startup>1</load-on-startup>

 </servlet>

 <servlet-mapping>

     <servlet-name>AxisServlet</servlet-name>

     <url-pattern>/services/*</url-pattern>

 </servlet-mapping>
另外特别需要注意的是，需要把axis2中的axis2.xml文件至于WEB-INF目录下

4. maven的项目管理文件pom.xml

5. 发布程序到tomcat或其他J2EE服务器，启动服务器，就可在浏览器中通过如下URL,http://localhost/demo.axis2.jaxws/services/Notice?wsdl ,看到services定义了，说明服务发布成功

6. 客户端访问服务代码

 import org.apache.axiom.om.OMAbstractFactory;

 import org.apache.axiom.om.OMElement;

 import org.apache.axiom.om.OMFactory;

 import org.apache.axiom.om.OMNamespace;

 import org.apache.axis2.Constants;

 import org.apache.axis2.addressing.EndpointReference;

 import org.apache.axis2.client.Options;

 import org.apache.axis2.client.ServiceClient;

 public class NoticeClient {

     private static EndpointReference targetEPR = new EndpointReference(

             "http://localhost/demo.axis2.jaxws/services/Notice");

     public static OMElement getByNoticeId(Integer noticeId) {

         OMFactory fac = OMAbstractFactory.getOMFactory();

         OMNamespace omNs = fac.createOMNamespace("http://core.jaxws.axis2.demo/", "tns");

         OMElement method = fac.createOMElement("getByNoticeId", omNs);

         OMElement value = fac.createOMElement("noticeId", omNs);

         value.addChild(fac.createOMText(value, noticeId.toString()));

         method.addChild(value);

         return method;

     }

     public static OMElement queryNotices(Integer supId, Integer status, String releaseTime) {

         OMFactory fac = OMAbstractFactory.getOMFactory();

         OMNamespace omNs = fac.createOMNamespace("http://core.jaxws.axis2.demo/", "tns");

         OMElement method = fac.createOMElement("queryNotices", omNs);

         OMElement value = fac.createOMElement("supId", omNs);

         value.addChild(fac.createOMText(value, supId.toString()));

         method.addChild(value);

         value = fac.createOMElement("status", omNs);

         value.addChild(fac.createOMText(value, status.toString()));

         method.addChild(value);

         value = fac.createOMElement("releaseTime", omNs);

         value.addChild(fac.createOMText(value, releaseTime));

         method.addChild(value);

         return method;

     }

     public static void main(String[] args) {

         try {

             Options options = new Options();

             options.setTo(targetEPR);

             options.setTransportInProtocol(Constants.TRANSPORT_HTTP);

             ServiceClient sender = new ServiceClient();

             sender.setOptions(options);

             System.out.println("getByActivityId start");

             OMElement result = sender.sendReceive(getByNoticeId(1));

             System.out.println(result.toString());

             System.out.println("queryByReleaseTime start!");

             result = sender.sendReceive(queryNotices(10000, 1, "2013-07-03T16:07:21+08:00"));

             System.out.println(result.toString());

         } catch (Exception e) {

             e.printStackTrace();

         }

     }
