使用到process和runtime兩個類，返回值通過process類的getinputstream()方法獲取

調用shell腳本，判斷是否正常執行，如果正常結束，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); }} |
以上這篇java調用shell命令并獲取執行結果的示例就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持服務器之家。
