生活随笔收集整理的這篇文章主要介紹了 jnotify监控linux系统,jnotify linux使用记录小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

今天使用jnotify，遇到了一些問題記錄下

程序啟動

java.lang.UnsatisfiedLinkError: no jnotify in java.library.path

這是沒有指定jnotify?library 需在啟動腳本加 -Djava.library.path=.? ?(-Djava.library.path=/monitor/jnotify/) jnotify路徑

libjnotify.so 這個要根據(jù)自己的系統(tǒng)選擇對應(yīng)位數(shù)的文件不然會報這個錯，默認(rèn)32位，修改吧64位的替換掉外面的
