我在我的JSF应用程序中实现了log4j日志记录。我的log4j.properties文件是这样的
log4j.rootLogger=DEBUG, stdout, fileout
#----------------------------- All logging to console-----------------------------
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d] [%t] %5p %c{1}:%L - %m%n
# ------------------------------ All Logging to File------------------------------
log4j.appender.fileout = org.apache.log4j.RollingFileAppender
log4j.appender.fileout.layout = org.apache.log4j.PatternLayout
log4j.appender.fileout.layout.ConversionPattern = [%d] [%t] %5p %c{1}:%L - %m%n
log4j.appender.fileout.File = ${catalina.home}/logs/Portal-alllogs.log
log4j.appender.fileout.MaxFileSize =2MB
log4j.appender.fileout.MaxBackupIndex =2
现在我的应用程序中出现以下异常，因为数据库已关闭
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (ORA-01034: ORACLE not available

WARNING: Failed to register in JMX: javax.naming.NamingException: Cannot create PoolableConnectionFactory (ORA-01034: ORACLE not available
问题是上面的异常显示在catalina.out中，但不在我的日志文件中
任何人都可以解释一下原因吗？ 提前致谢
更新：我只是在部署WAR文件时看到此日志

答案 0 :(得分：0)
这可能是权限问题 - 请检查$ {catalina.home} / logs目录的所有者和权限。
答案 1 :(得分：0)
您是否在代码中捕获该异常并处理它，即记录它？如果没有，为什么你希望出现在你的日志中？
答案 2 :(得分：0)
如果它不是权限问题：验证$ {catalina.home}解析到你认为它的位置 - 尝试使用“原始”绝对路径来排除这种情况。
答案 3 :(得分：0)
你确定异常实际上是LOGDED到stdout，而不仅仅是打印到stdout吗？你能看到你的控制台上的转换模式吗？
