改路徑之前也是這個錯，改完了自己把目錄都建好了，還是這個錯，不太懂log4j，網上說是tomcat啥訪問目錄權限問題，請教下

你把根目錄磁盤的權限 改為允許寫讀 試試

我只改了路徑，沒去創建相應的log文件夾，直接運行過了

細心讀取錯誤信息會發現無法創建和無法設置日志文件。
查看是否配置了log4j.properties文件，如果正確配置了進行下一步。
查看配置文件項目中單項是否配置正確例如（4），
log4j.appender.error.File=${LOG_PATH}/${LOG_FILE}_error.log2019-04-17
我也遇到這個錯誤了，我自己新建立的logs目錄權限都改成775了 還是報這個錯 ，我是在mac上做的
