getProperties()方法：
public Properties getProperties() {
InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("resources/constant.properties");
Properties p = new Properties();
try {
p.load(inputStream);
} catch (IOException e1) {
System.out.println("读取constant.properties文件失败"+ e1);
e1.printStackTrace();
return p;
Base.java中的bytesSub2String()方法：
* @input src 待截取字节数组
* start 待截取字节数组的开始位置
* src_size 截取的长度 == 数据类型的长度
* @output String 字节截取转换成String后的结果
* **/
public static String bytesSub2String(byte[] src,int start,int src_size) {
byte[] resBytes = new byte[src_size];
System.arraycopy(src, start, resBytes, 0, src_size);
// System.out.println(" len ==" +resBytes.length
// + " sub_bytes = " + bytes2Int1(resBytes));
return bytes2String(resBytes);
// byte[] --> String
public static String bytes2String(byte b[]){
String result_str = new String(b);
return result_str;
常量全在constant.properties中写着。接下来一般都是把这个写入定时任务中，因为token一般都有有效时间，过了有效时间需要重新申请。所以写入定时任务中，让定时任务执行并获取token。
