我正在嘗試在 WebLogic 9 上部署應用程序并且控制臺日志不斷拋出此錯誤：log4j:ERROR setFile(null,true) call failed.java.io.FileNotFoundException: logs\sd.log (The system cannot find the path specified)    at java.io.FileOutputStream.openAppend(Native Method)    at java.io.FileOutputStream.<init>(FileOutputStream.java:177)    at java.io.FileOutputStream.<init>(FileOutputStream.java:102)    at org.apache.log4j.FileAppender.setFile(FileAppender.java:272)    at org.apache.log4j.FileAppender.activateOptions(FileAppender.java:151)    at org.apache.log4j.DailyRollingFileAppender.activateOptions(DailyRollingFileAppender.java:206)    at org.apache.log4j.config.PropertySetter.activate(PropertySetter.java:247)    at org.apache.log4j.config.PropertySetter.setProperties(PropertySetter.java:123)    at org.apache.log4j.config.PropertySetter.setProperties(PropertySetter.java:87)    at org.apache.log4j.PropertyConfigurator.parseAppender(PropertyConfigurator.java:645)    at org.apache.log4j.PropertyConfigurator.parseCategory(PropertyConfigurator.java:603)    at org.apache.log4j.PropertyConfigurator.configureRootCategory(PropertyConfigurator.java:500)    at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:406)    at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:432)    at org.apache.log4j.helpers.OptionConverter.selectAndConfigure(OptionConverter.java:460)    at org.apache.log4j.LogManager.<clinit>(LogManager.java:113)    at org.apache.log4j.Logger.getLogger(Logger.java:94)    at com.sherwin.sd.web.filter.RedirectFilter.logger(RedirectFilter.java:253)    at com.sherwin.sd.web.filter.RedirectFilter.init(RedirectFilter.java:113)    at weblogic.servlet.internal.FilterManager$FilterInitAction.run(FilterManager.java:309)    at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321)我可以看到它指向反斜杠路徑而不是正確的正斜杠。之后，我檢查回 log4j.properties 并確保 logs/sd.log 的路徑正確，文件夾和日志文件也在那里：但是，由于反斜杠，它仍然向我拋出路徑未找到錯誤。什么可能出錯？
