Question

我试图在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.

log4j:ERROR Either File or DatePattern options are not set for appender [R].

java.io.FileNotFoundException：logs \ sd.log（系统找不到指定的路径）

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

https://jansson.readthedocs.io/en/2.8/apiref.html#c.json_dumps

但是，由于反斜杠，它仍然使我找不到路径错误。可能出什么问题了？

Answer 1

我很累给sd.log一个绝对路径（/logs/sd.log），但它不起作用。最后，我只是将 log4j.appender.R.File 路径更改为sd.log，而FileNotFoundException错误消失了。

log4j指向错误的反斜杠日志路径
