文件存储配置信息增 改 删 查
本示例以properties格式文件为主
如果你自己想要其他格式的文件如txt等等，可以自己修改代码
如果你想要自己的解析格式也可以修改conf代码中的parseLine方法里的解析格式
1.配置文件：bsidinfo.properties
###gsmconf 存储短信发送配置信息，message：发送命令内容，comid=COM2端口号大写，baud=115200为短信设备的波特率，根据需求修改#### [gsmconf] message=SMS:SET+WAKEUP comid=COM3 baud=9600 ###connectioninfo连接流媒体服务器的配置信息，IP、端口号port、用户名username 密码password，根据需求修改## [connectioninfo] port=7660 username=root password=6973hiktb ip=202.91.248.243 ###以下是所有终端的配置信息，[]里代表的是终端的名称不能重复，bsid终端id号，simid手机号，status默认为0## ##这里你可以添加、修改、删除、任何终端，但是请慎重处理 [红满线85号塔_1013] bsid=000001013 simid=15349919673 status=0 [3G-000001143] bsid=000001143 simid=13396716823 status=0
