log4j 指向错误的反斜杠日志路径

Question

我正在尝试在 WebLogic 9 上部署应用程序并且控制台日志不断抛出此错误：

log4j:ERROR setFile(null,true) call failed.

java.io.FileNotFoundException: logs\sd.log (The system cannot find the path specified)

我可以看到它指向反斜杠路径而不是正确的正斜杠。之后，我检查回 log4j.properties 并确保 logs/sd.log 的路径正确，文件夹和日志文件也在那里：

但是，由于反斜杠，它仍然向我抛出路径未找到错误。什么可能出错？

Answer 1

我厌倦了给出sd.log绝对路径 (&nbsp;/logs/sd.log) 但它不起作用。最后我只是改变了log4j.appender.R.File路径sd.log，FileNotFoundException错误就消失了。
