5、消息编码请求消息:publicclassRpcRequest{???privateStringrequestId;??privateStringclassName;??privateStringmethodName;??privateClass[]parameterTypes;??privateObject[]parameters;???publicStringgetRequestId(){????returnrequestId;??}???publicvoidsetRequestId(StringrequestId){????this.requestId=requestId;??}???publicStringgetClassName(){????returnclassName;??}???publicvoidsetClassName(StringclassName){????this.className=className;??}???publicStringgetMethodName(){????returnmethodName;??}???publicvoidsetMethodName(StringmethodName){????this.methodName=methodName;??}???publicClass[]getParameterTypes(){????returnparameterTypes;??}???publicvoidsetParameterTypes(Class[]parameterTypes){????this.parameterTypes=parameterTypes;??}???publicObject[]getParameters(){????returnparameters;??}???publicvoidsetParameters(Object[]parameters){????this.parameters=parameters;??}}?RpcRequest响应消息:publicclassRpcResponse{???privateStringrequestId;??privateStringerror;??privateObjectresult;???publicbooleanisError(){????returnerror!=null;??}???publicStringgetRequestId(){????returnrequestId;??}???publicvoidsetRequestId(StringrequestId){????this.requestId=requestId;??}???publicStringgetError(){????returnerror;??}???publicvoidsetError(Stringerror){????this.error=error;??}???publicObjectgetResult(){????returnresult;??}???publicvoidsetResult(Objectresult){????this.result=result;??}}?RpcResponse消息序列化和反序列化工具:(基于Protostuff实现)publicclassSerializationUtil{???privatestaticMap,Schema>cachedSchema=newConcurrentHashMap<>();???privatestaticObjenesisobjenesis=newObjenesisStd(true);???privateSerializationUtil(){??}???@SuppressWarnings("unchecked")??privatestaticSchemagetSchema(Classcls){????Schemaschema=(Schema)cachedSchema.get(cls);????if(schema==null){??????schema=RuntimeSchema.createFrom(cls);??????if(schema!=null){????????cachedSchema.put(cls,schema);??????}????}????returnschema;??}???/**???*序列化(对象->字节数组)???*/??@SuppressWarnings("unchecked")??publicstaticbyte[]serialize(Tobj){????Classcls=(Class)obj.getClass();????LinkedBufferbuffer=LinkedBuffer.allocate(LinkedBuffer.DEFAULT_BUFFER_SIZE);????try{??????Schemaschema=getSchema(cls);??????returnProtostuffIOUtil.toByteArray(obj,schema,buffer);????}catch(Exceptione){??????thrownewIllegalStateException(e.getMessage(),e);????}finally{??????buffer.clear();????}??}???/**???*反序列化(字节数组->对象)???*/??publicstaticTdeserialize(byte[]data,Classcls){????try{??????Tmessage=(T)objenesis.newInstance(cls);??????Schemaschema=getSchema(cls);??????ProtostuffIOUtil.mergeFrom(data,message,schema);??????returnmessage;????}catch(Exceptione){??????thrownewIllegalStateException(e.getMessage(),e);????}??}}?SerializationUtil由于处理的是TCP消息,本人加了TCP的粘包处理Handlerchannel.pipeline().addLast(newLengthFieldBasedFrameDecoder(65536,0,4,0,0))消息编解码时开始4个字节表示消息的长度,也就是消息编码的时候,先写消息的长度,再写消息。GCJava中的堆也是GC收集垃圾的主要区域。注意:如果我们选择与偏移值相加而不是异或会得到更糟糕的结果。总结通过探索哈希值的产生过程,我们找到了将352个关键字的冲突次数从103次降到68次的方法。基于REST的软件体系结构风格(SoftwareArchitectureStyle)称之为面向资源体系架构(Resource-orientedArchitecture,ROA)。

为提高高三一轮复习课堂教学效率,总结交流复课教学经验,推动复课备考工作高效有序进行,918日,北关校区开展了高三一轮复习示范课教学活动。教学二处主任王伟民、副主任郭亚宁和全体高三教师参加了此次听评课活动。


 

本次活动共有10位教师承担示范课任务。老师们课前精心准备、巧妙设计,结合自己的教学经验从规划、量化和与学生对话等方面对学生们进行了指导性教学。教学内容丰富,并能结合相关的高考题分析详实,语言表述诙谐有趣,使学生在轻松愉快的气氛中获取了知识。课后各教研组对示范课进行了评讲,并就高三教学中的困惑、难题进行了交流探讨。


 

本次示范课的开展,使老师们进一步明确了一轮复习的方向,大家认为只有在一轮复习中重基础落实到位,抓细节全面覆盖,勤反思长坚持才能做到复课的有效性。(文/董乐阳
