使用java读取linux配置文件 [英] read linux config files using java

问题描述

嗨我需要一些帮助，在我的项目中使用java中的构建应用程序从Linux系统读取配置文件，我不会从这个文件中显示一些这样的值

 //配置文件中的代码
子网192.168.1.0网络掩码255.255.255.0 {
范围192.168.1.128 192.168.1.254; 
 option subnet-mask 255.255.255.0; 
选项广播地址192.168.1.255; #commnet这里
 .... 
} 

在应用程序中播种它应该打印类似的东西

网络1：192.168.1.0/24 
范围：从192.168 .1.128到192.168.1.254 
面具：255.255.255.0 
广播：192.168.1.255 

所以我需要从指定的args读取值，如option subnet-mask到行的末尾是;并返回值255.255.255.0。如果有评论＃不做任何事情只需转到下一行。并且对于每个配置从{开始并以}结束。所以当凸轮到}时应该停止。然后去那里的下一个网络。感谢帮助

解决方案

用Java读取文件并解析字符串相对容易。请参阅 http://docs.oracle.com/javase/tutorial/essential/io/index.html [ ^ ]和 http://docs.oracle.com/javase/tutorial/java/data/index.html [ ^ ]

hi i need some help in my project a build application in java that read config files from Linux system and i wont to show some value from this files like this

//the code in config file
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.128 192.168.1.254;
option subnet-mask              255.255.255.0;
option broadcast-address        192.168.1.255;#commnet here
....
}

sow in the application it should be print something like that

network 1 : 192.168.1.0/24
  range : from 192.168.1.128 to 192.168.1.254
  mask : 255.255.255.0
  broadcast : 192.168.1.255

so i need to read the value from specified args like "option subnet-mask" to the end of the line is ";" and return just the value "255.255.255.0". and if there comment "#" don't do anything just go to next line. and for each configuration is start from "{" and end at "}". so when is cam to "}" is should be stopped. and go for the next network if there. thanks for helping

Reading files in Java and parsing strings is relatively easy. See http://docs.oracle.com/javase/tutorial/essential/io/index.html[^] and http://docs.oracle.com/javase/tutorial/java/data/index.html[^].
