数据传输部分

传出数据的类DataTransIn：其中 syncDataToServer()用来接收传入数据，具体代买解释如下

      /**
     * 把byte数据传到服务器的具体传送部分
     * @param b  数据字节数组
     */
    public boolean transDate(byte b[]){
        HttpPost request = new HttpPost(StaticFinalVariable.URL_Str);
        ByteArrayEntity byteArrayEntity = new ByteArrayEntity(b);
        boolean isOk=false;
        try {
            request.setEntity(byteArrayEntity);
            HttpResponse response = new DefaultHttpClient().execute(request);
            Log.e("error",response.getStatusLine()+"");
            if(response.getStatusLine().getStatusCode()==200){
                isOk=true;
                String msg = EntityUtils.toString(response.getEntity());
                Log.e("error",msg);                
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return isOk;
    }
    /**
     * 把数据传到服务器
     * @param treeMap 数据map
     * @param id 四位整数的id号
     * @param isZip  0表示不压缩，其他的表示压缩
     */
    public boolean syncDataToServer(TreeMap<String, Integer> treeMap,String id,boolean gzip) throws DigitException{
        
        InDataTobyteArr(treeMap); 
        addIdToArr(id);   //
        compressCon(gzip);
 
        
        return transDate();
    }
    /**
     * 自定义压缩下届
     * @param treeMap
     * @param minlength 压缩下届
     * @throws DigitException
     */
    public void syncDataToServer(TreeMap<String, Integer> treeMap,String id,long minlength) throws DigitException{
        
        if(sensorDataBytes.getSumByte()>minlength){
            syncDataToServer(treeMap, id,true);
        }
        else{
            syncDataToServer(treeMap,id,false);
        }
    }
    /**
     * 按照系统自定义的量去决定是否压缩
     * @param treeMap
     * @throws DigitException
     */
    public void syncDataToServer(TreeMap<String, Integer> treeMap,String id) throws DigitException{
        if(sensorDataBytes.getSumByte()>StaticFinalVariable.MIN_LENGTH){
            syncDataToServer(treeMap,id, true);
        }
        else{
            syncDataToServer(treeMap, id,false);
        }
    }

 

 

 

服务器接收数据类DataTransOut：

其中用runResult()解析ServletInputStream，printMap（）打印传感器数据map ，getId（），getSensorData（String） 获取相应的数据

代码如下：

/**
     *   将整个request 的流全部解析出来。
     * @param request  传入的HttpServletRequest 参数
     * @throws IOException
     */
    public void runResult(HttpServletRequest request) throws IOException {
        readByteArray(request.getInputStream());
        readId(StaticFinalVariable.ID_BYTES);
        outDataFrombyteArr(StaticFinalVariable.ID_BYTES);
    }
    /**
     * 供测试用，打印传感器数据的map;
     */
    public void printMap(){
        System.out.println(treeMap);
    }
    /**
     * 获取name 传感器的数值
     * @param name  表示传感器名称
     * @return
     */
    public int getSensorData(String name){
        return treeMap.get(name);
    }
    /**
     * 获取传入的id
     * @return
     */
    public String getId(){
        return String.valueOf(id);
    }
    

使用的范例代码：

        button3.setOnClickListener(new View.OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                TreeMap<String, Integer> treeMap =new TreeMap<String, Integer> ();
                treeMap.put("hello", 1);
                treeMap.put("acceleration1",100);
                treeMap.put("temperature",2000);
                treeMap.put("acceleration2", 10000);
                treeMap.put("acceleration3",65535 );
                try {
                    Log.e("treeMap:",treeMap+"");
                    if(trans.syncDataToServer(treeMap,id,false)){
                        toastShow("发送成功");
                    }
                    else{
                        toastShow("发送失败");
                    }
                } catch (DigitException e) {
                    // TODO Auto-generated catch block
                    Toast.makeText(MainActivity.this,e.getMessage(), Toast.LENGTH_SHORT);
                    
                    e.printStackTrace();
                }
                Log.e("error", "testEntity after test");
            }
        });

    /**
     * 转换类
     */
    private DataTransOut trans=new DataTransOut();
    
    
    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html");
        response.setCharacterEncoding("utf-8");
        PrintWriter out = response.getWriter(); 
        
        trans.runResult(request);
        trans.printMap();
        System.out.println(trans.getId());
        trans.getSensorData("acceleration1");
        
        outputMap();
        String msg ="hello";
        out.print(msg);

        out.close();

            throws ServletException, IOException {
        doGet(request,response);
