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)    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 ( /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。
