WEBSERVICE创建总结.docx

JAX-WS WEB SERVICE编写步骤1 新建项目在Eclipse中新建一个“Dynamic Web project”项目，项目名称取为ghtotMisService。 2 引入包文件在项目中引用jaxws227包；3 编写WebService步骤3.1 在项目中建立包f；3.2 在f包中创建GtServiceIntf.java接口文件，定义如下： package f;public interface GtServiceIntf public String Login(String inData);public String GetData(String sessionID,String serviceID,String inData);public String UpdData(String sessionID,String serviceID,String inData);public String Heartbeat(String sessionID); 3.3 在f包中创建接口实现文件GtServiceImpl.javapackage f;import javax.annotation.Resource;import javax.jws.*;import javax.jws.soap.SOAPBinding;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpSession;import javax.xml.ws.WebServiceContext;import javax.xml.ws.handler.MessageContext;import com.ghtot.session.core.*;WebService(name = ghtotmis) SOAPBinding(style = SOAPBinding.Style.RPC)public class GtServiceImpl implements GtServiceIntf Resourceprivate WebServiceContext wsContext;OverrideWebMethodpublic String Login(WebParam(name=inData) String inData) MessageContext mc = this.wsContext.getMessageContext();HttpServletRequest req = (javax.servlet.http.HttpServletRequest) mc.get(MessageContext.SERVLET_REQUEST);HttpSession session = (javax.servlet.http.HttpServletRequest) mc.get(MessageContext.SERVLET_REQUEST).getSession(); session.setAttribute(userInfo, inData);return session.getId();OverrideWebMethodpublic String GetData(WebParam(name=sessionID) String sessionID, WebParam(name=serviceID) String serviceID, WebParam(name=inData) String inData) MessageContext mc = wsContext.getMessageContext();HttpServletRequest req = (javax.servlet.http.HttpServletRequest) mc.get(MessageContext.SERVLET_REQUEST);HttpSession session = MySessionContext.getInstance().getSession(sessionID);if (session = null) return sessionID无效;return ok;OverrideWebMethodpublic String UpdData(WebParam(name=sessionID) String sessionID, WebParam(name=serviceID) String serviceid, WebParam(name=inData) String inData) return UpdData;OverrideWebMethodpublic String Heartbeat(WebParam(name=sessionID) String sessionID) return Hearbeat;3.4 在WEB-INF新建web.xml，配置如下： GtService com.sun.xml.ws.transport.http.servlet.WSServlet GtService /gtService 3.5 在WEB-INF新建sun-jaxws.xml，这个文件提供一个WEB服务端点，用来连接WSServlet实例和服务实现类。服务器端已经完成，在Eclipse中启动服务进行测试，在浏览器中输入http:/localhost:8080/ghtotMisService/gtService?wsdl就可以看到WSDL文件了。4 增加session管理4.1 增加包com.ghtot.session.core4.2 增加session实现类MySessionContext.javapackage com.ghtot.session.core;import java.util.HashMap;import javax.servlet.http.HttpSession;public class MySessionContext private static MySessionContext instance;private HashMap mymap;private MySessionContext() mymap = new HashMap();public static MySessionContext getInstance() if (instance = null) instance = new MySessionContext();return instance;public synchronized void AddSession(HttpSession session) if (session != null) mymap.put(session.getId(), session);public synchronized void DelSession(HttpSession session) if (session != null) mymap.remove(session.getId();public synchronized HttpSession getSession(String session_id) if (session_id = null) return null;return (HttpSession) mymap.get(session_id); 4.3 增加session实现类SessionListener.javapackage com.ghtot.session.core;import java.text.SimpleDateFormat;import java.util.HashMap;import java.util.Map;import javax.servlet.http.HttpSession;import javax.servlet.http.HttpSessionEvent;import javax.servlet.http.HttpSessionListener;public class SessionListener implements HttpSessionListener public static Map userMap = new HashMap();private MySessionContext myc=MySessionContext.getInstance();Overridepublic void sessionCreated(HttpSessionEvent httpSessionEvent) myc.AddSession(httpSessionEvent.getSession();Overridepublic void sessionDestroyed(HttpSessionEvent httpSessionEvent) HttpSession session = httpSess
