关于webService 客户端 调用 对象数组 问题

我自己写的一个服务端需要的参数是一个对象数组 比如 public String getAge(Student[] ss ) { return ss[0].getAge(); } 这种形式的， 但是在客户端调用的时候 服务端接收到的 ss 对象数组的长度都为1，里面的对象的值都为null,哪位 大神指导一下新人啊 **下面是客户端调用代码** public static void main(String [] args) throws ServiceException, MalformedURLException, RemoteException{ String nameSpace="http://impl.webservice"; String method="getAge"; Service service = new Service(); Call call=(Call)service.createCall(); call.setTargetEndpointAddress(new java.net.URL("http://localhost:8070/TEST/services/testMyService?wsdl")); call.setUseSOAPAction(true); Student[] ss=new Student[2]; Student s0=new Student(); s0.setAge("123"); s0.setName("57"); ss[0]=s0; Student s1=new Student(); s1.setAge("123"); s1.setName("213"); ss[1]=s1; QName qn =new QName(nameSpace,method); call.setOperationName(qn); call.registerTypeMapping(Student.class, qn, new org.apache.axis.encoding.ser.BeanSerializerFactory(Student.class, qn), new org.apache.axis.encoding.ser.BeanDeserializerFactory(Student.class, qn)); String ret = (String) call.invoke(new Object[] {ss}); System.out.println(ret); }

CXF动态生成client调用服务端，服务端收到参数为空，请教如何解决？

请教大家一个问题。 java做客户端，c#做服务端。java用apache.cxf的DynamicClientFactory或者JaxWsDynamicClientFactory根据wsdl生成client，调用服务端传递UserSyncData对象，服务端方法收到的参数对象是null，请问大家有解决办法吗？（需求：一定要用动态生成客户端的方式） 传递的对象UserSyncData 是jdk或者用cxf的wsdl2java在本地生成的pojo，服务端接受的参数就是空。如果用代理服务类的方式调用，是可以成功的，可以正常收到参数。但是我的项目要求用动态方式调用，所以来请教大家 java中调用的代码 ![CSDN移动问答][1] .net服务端方法：打断点看到userSyncData为null ![CSDN移动问答][2] [1]: http://c.hiphotos.baidu.com/zhidao/pic/item/adaf2edda3cc7cd95ffea4b53b01213fb90e918f.jpg [2]: http://c.hiphotos.baidu.com/zhidao/pic/item/738b4710b912c8fce13d66a1fe039245d788218b.jpg 我自己分析可能是pojo对象在java和c#中定义要达成某种规范，仅是猜测，也不知道应该怎么做。以前和同时调试hessian的时候，要求java和c#的pojo必须一模一样，包括namespace也必须一样，我按这个方法试了以后也没用。

客户端调用web service服务异常

运行在不同机器上的客户端可以共用一个线程向服务端发送不同的数据请求吗

没有开线程之前服务端开启之后总是卡死，必须用资源管理器才能结束任务，后来我打算用线程来负责跟客户端的通信，发现无论开几个客户端，线程名都一样，应该是共用线程了，难道是我两个客户端运行在一个机器上了？？现在问题就在于两个客户端共用一个线程与服务端通信查询不同数据时，查询的数据是否是自己需要的数据？代码贴出来 ``` ok.addActionListener(new ActionListener() {//单击按钮开启服务端 @Override public void actionPerformed(ActionEvent arg0) { tip.setText(" 服务端已启动_"); CreateThread ct=new CreateThread(); Thread t1=new Thread(ct);//建立线程 t1.start(); //线程共用问题应该是在这 } }); Run(): @Override public void run() { try { startSocket();//不开线程直接调用startSocket()会导致服务端卡死 } catch (IOException e) { System.out.println("服务端口已开启"); } } 接收客户端请求的startSocket()： private void startSocket() throws IOException { ServerSocket ss=new ServerSocket(6666); Socket server=null; while(true) { //System.out.println(server); server=ss.accept(); if(server!=null) { System.out.println(server); InputStream is=server.getInputStream(); byte[] message=new byte[1024]; int len=is.read(message); String msg=new String(message,0,len); is.close(); server.close(); } } } ```

socket客户端如何主动断开与服务器的连接

这里是客户端 new Thread(new Runnable() { @Override public void run() { try { final Socket socket=new Socket("192.168.43.39",8080); OutputStream out=socket.getOutputStream(); PrintWriter pw=new PrintWriter(out); pw.write("123"); pw.flush(); socket.shutdownOutput(); socket.setSoTimeout(5000); InputStream inputStream=socket.getInputStream(); BufferedReader bufferedReader=new BufferedReader(new InputStreamReader(inputStream)); String client=null; while ((client=bufferedReader.readLine())!=null){ System.out.print("这里是客户端。服务器说:"+client); textView.setText("这里是客户端，"+client); } //关闭相关资源 inputStream.close(); bufferedReader.close(); pw.close(); out.close(); socket.close(); } catch (IOException e) { e.printStackTrace(); } } }).start(); ``` 这是服务器端 try { ServerSocket serverSocket=new ServerSocket(8080); System.out.print("服务器已启动，正在等待客户端连接...\n"); //记录客户端的数量 int count=0; //循环监听等待客户端的连接 while (true){ //调用accept()方法监听，等待客户端的连接 socket= serverSocket.accept(); System.out.print("服务器已连接客户端！\n"); //创建一个新的线程 ServerThread serverThread=new ServerThread(socket); //开启线程 serverThread.start(); count++; System.out.print("当前客户端的数量为："+count+"\n"); } } catch (IOException e) { e.printStackTrace(); } ```

dubbo服务端有返回，客户端接收到null的问题【紧急】

### 现象 服务端日志已经显示返回结果,结果为自定义对象 格式如下： ``` AcctQueryFacadeImpl.acctBalanceQuery00, resp=AcctBalanceQuery00Resp[uid=1355739,acctStatus=N,createTime=Fri Mar 04 21:36:31 CST 2016,updateTime=Wed Apr 20 19:52:24 CST 2016,acctId=4985191,balance=0,frozenBalance=0,withdrawBalance=0,respDesc=成功,respCode=000000], time=2ms ``` 客户端接收到的对象为null 该现象并不是必现， - 现象1：调用acctBalanceQuery00方法一天有几十万次，目前出现问题的仅3例 - 现象2：有2条失败数据，重试之后，1条成功，1条仍然失败 - 现象3：很多业务调用acctBalanceQuery00方法，但目前只有1个业务出问题，这些业务入参基本一样，（此现象也许是巧合） - 现象4：用dubbo telnet invoke acctBalanceQuery00方法，有结果返回，用出问题的数据invoke，也有结果返回，所有机器都试过 ### 环境 jdk1.8 dubbo版本 2.5.3 服务端4台，客户端10台左右 dubbo服务端配置如下： ``` <dubbo:application name="xxx" owner="yy"/> <dubbo:registry protocol="zookeeper" client="zkclient" address="${dubbo.zk.servers}" group="${dubbo.zk.group}"></dubbo:registry> <dubbo:protocol name="dubbo" port="20909"></dubbo:protocol> <dubbo:provider retries="0" timeout="6000"></dubbo:provider> <dubbo:service interface="xxxx" ref="xxx"></dubbo:service> ``` dubbo消费端配置: ``` <dubbo:application name="${application.name}" owner="${dubbo.application.owner}"/> <dubbo:registry protocol="zookeeper" client="zkclient" address="${dubbo.zk.servers}" group="${dubbo.zk.group}"></dubbo:registry> <dubbo:protocol name="dubbo" port="${dubbo.protocol.port}"></dubbo:protocol> <dubbo:monitor address="${dubbo.monitor.address}"></dubbo:monitor> <dubbo:consumer retries="0" timeout="6000" check="false"></dubbo:consumer> ```

xfire 客户端没有等待服务端返回，就向下执行,这样导致客户端获取不到返回值

服务端配置： <import resource="classpath:org/codehaus/xfire/spring/xfire.xml" /> <bean id="addressingHandler" class="org.codehaus.xfire.addressing.AddressingInHandler" /> <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> <property name="beanNames"> <list> <value>webServiceForPlaceRemote</value> </list> </property> </bean> <bean id="placeManager" class="com.rainsoft.yunReg.manage.PlaceManager" /> <!-- 场所编码生成，获取场所信息接口 --> <bean name="webServiceForPlaceRemote" class="org.codehaus.xfire.spring.ServiceBean"> <property name="serviceBean" ref="placeManager"></property> <property name="serviceClass" value="com.rainsoft.app.webservice.interfaces.WebServiceForPlace"></property> <property name="inHandlers"> <list> <ref bean="addressingHandler" /> </list> </property> </bean> 客户端调用： String url = "http://localhost:8080/yun_reg/service/WebServiceForPlace"; serviceFactory = new ObjectServiceFactory(); Service serviceModel = serviceFactory.create(WebServiceForPlace.class); WebServiceForPlace service=null; try { service = (WebServiceForPlace) new XFireProxyFactory().create(serviceModel,url); Map actionValues = new HashMap(); actionValues.put("areaCode", "342422"); actionValues.put("businessNature", "1"); actionValues.put("serviceType", "1"); String placeCode = service.savePlaceAndReturnPlaceCode(actionValues); System.out.println(placeCode); Map place = service.getPlace("65232810000001"); System.out.println(placeCode); } catch (MalformedURLException e) { e.printStackTrace(); } 服务端代码是执行了，但是客户端打印的都是null。客户端直接向下执行，并不会等待服务端执行结束

客户端读取服务端回执信息时出现error：org.apache.http.ConnectionClosedException

具体error: org.apache.http.ConnectionClosedException: Premature end of Content-Length delimited message body 。 （好像是回执信息数据太大） 网上搜了下，大概意思就是 ： 本来在接管数据量，程序员显式封闭了连接（同步调用），而netty是异步处理惩罚，当连接被显式封闭后，后来的数据再次触发读写操纵时贯穿连接已经不成用。所以呈现读不一完全数据的题目。 服务端关键代码: InputStream is = t.getRequestBody(); BufferedReader reader = new BufferedReader(new InputStreamReader(is)); StringBuffer temp=new StringBuffer(); String lineMessage; while ((lineMessage = reader.readLine()) != null) { temp.append(lineMessage); } reader.close(); is.close(); String respXml=DuXmlDoc.execute(temp.toString()); System.out.println("!!"+respXml); t.sendResponseHeaders(2000, respXml.length()); OutputStream os = t.getResponseBody(); os.write(respXml.getBytes()); os.flush(); os.close(); t.close(); 客户端关键代码: HttpResponse response = httpClient.execute(httpPost); HttpEntity entity = response.getEntity(); StringBuffer returnMessage = new StringBuffer(); System.out.println(response.getStatusLine()); if (entity != null) { System.out.println("Response content length: " + entity.getContentLength()); BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(entity.getContent())); String lineMessage; while ((lineMessage = bufferedReader.readLine()) != null) { returnMessage.append(lineMessage); } bufferedReader.close(); }

C++ TCP CAsyncSocket一服务端对应多客户端的问题

今天在使用WCF调试时出现了以下异常  ”无法处理消息。这很可能是因为操作“http://tempuri.org/IUserInfo/GetUserUserList”不正确，或因为消息包含无效或过期的安全上下文令牌，或因为绑定之间出现不匹配。如果由于未处于活动状态导致服务中止了该通道，则安全上下文令牌无效。若要防止服务永久中止闲置会话，请增加服务终结点绑定上的接收超时“ 服务器端的配置如下 ``` <system.serviceModel> <!--测试配置--> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_IUserInfo" maxBufferPoolSize="12000000" maxReceivedMessageSize="12000000" useDefaultWebProxy="false"> <readerQuotas maxStringContentLength="12000000" maxArrayLength="12000000"/> <security mode="None"/> </binding> </wsHttpBinding> </bindings> <services> <service name="WCFMonitorInterface.UserInfoService"> <!-- Service Endpoints --> <endpoint address="http://192.168.14.18:20005/UserInfoService/mex" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IUserInfo" contract="WCFMonitorInterface.Interfaces.IUserInfo"> </endpoint> </service> </services> <behaviors> <serviceBehaviors> <behavior> <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false --> <serviceMetadata httpGetEnabled="true" httpGetUrl="http://192.168.14.18:20005/UserInfoService/metadata"/> <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 --> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> <protocolMapping> <add binding="basicHttpsBinding" scheme="https" /> </protocolMapping> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel> ``` 客户端配置如下 ``` <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_IUserInfo" maxBufferPoolSize="12000000" maxReceivedMessageSize="12000000" useDefaultWebProxy="false"> <readerQuotas maxStringContentLength="12000000" maxArrayLength="12000000"/> <security mode="None"></security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://192.168.14.18:20005/UserInfoService" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IUserInfo" contract="UserInfoService.IUserInfo" name="WSHttpBinding_IUserInfo"> <identity> <userPrincipalName value="ludi\ODST" /> </identity> </endpoint> </client> </system.serviceModel> ``` 由于WCF服务是寄宿在一个控制台程序下，也做了一些初始设置，代码如下 ``` host.AddServiceEndpoint(typeof(IUserInfo), new WSHttpBinding(), uri); if (host.Description.Behaviors.Find<ServiceMetadataBehavior>() == null) { ServiceMetadataBehavior behavior = new ServiceMetadataBehavior(); behavior.HttpGetEnabled = true; behavior.HttpGetUrl = new Uri(MetaUri); host.Description.Behaviors.Add(behavior); } host.Opened += delegate { Console.WriteLine("WCF服务已开启"); Console.WriteLine("WCF服务元数据地址："+MetaUri); }; host.Open(); ``` 以上，望解答，谢谢

netty服务端接收报文由于客户端计算长度错误阻塞在decoder中

代码是这个逻辑，传输内容的前8位代表长度，获取长度后，在收到信息的长度等于获取到的内容长度时。将信息添加处理。但是如果客户端调用时计算长度错误，就会在这里阻塞。这个情景使用IdleStateHandler 时无法进行超时处理的。该如何才能够设置这个超时呢。 ``` protected void decode(ChannelHandlerContext context, ByteBuf byteBuf, List<Object> list) { int length = byteBuf.readableBytes(); if(length==0) return; byte[] message = new byte[length]; byteBuf.readBytes(message); if (content != null) { System.arraycopy(message,0,content,receiveLength+8,length); } receiveLength +=length; //如果还没获取总长度 if (xmlLength == 0) { byte[] l= Arrays.copyOf(message,8); xmlLength = Integer.parseInt(new String(l)); content=new byte[xmlLength+8]; System.arraycopy(message,0,content,0,length); } if (xmlLength == receiveLength) { //将报文信息打印到控制台查看 if(content!=null) { String recv = new String(content, StandardCharsets.UTF_8); log.info("收到报文：" + recv); log.info("总长度：[" + xmlLength + "] 接收长度：[" + receiveLength + "]"); list.add(recv); } } } ```

webservice服务器返回值为null

用myeclipse的jax-ws做的服务器，按照如下教程做的。 http://blog.csdn.net/flightme/article/details/6977191 服务器挂的tomcat7，用wsdl2objc转换为xcode的代码，在xcode中调用，以下是xcode的教程。 http://www.devdiv.com/iOS_iPhone-_wsdl_objc_web_service_soap_sample-thread-36521-1-1.html 现在的问题是，苹果的客户端发送数据成功，但是jax-ws的服务器端接收到的是null，但是客户端能够收到服务器端的返回值。 求大神帮忙~小弟先在此谢过。
