Struts应用程序无法以log4j启动。
怎么了?
这是log4j.properties
:
# Direct to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
# Root logger option
log4j.rootLogger=INFO, stdout
# Good for troubleshooting
log4j.logger.org.hibernate=INFO
# Log JDBC parameters
log4j.logger.org.hibernate.type=ALL
由于日志记录错误,Struts启动失败。

由于SLF4J(Simple Logging Facade for Java)的问题,而不是Log4j,您的应用程序服务器无法启动。你可能是:
