使用到process和runtime两个类，返回值通过process类的getinputstream()方法获取

调用shell脚本，判断是否正常执行，如果正常结束，process的waitfor()方法返回0

public static void callshell(string shellstring) { try { process process = runtime.getruntime().exec(shellstring); int exitvalue = process.waitfor(); if (0 != exitvalue) { log.error("call shell failed. error code is :" + exitvalue); } } catch (throwable e) { log.error("call shell failed. " + e); }} |
以上这篇java调用shell命令并获取执行结果的示例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
