java - 更改 Tomcat 的日志级别不起作用

Question

我正在尝试在 Tomcat 上配置 Log4j，所以这是我的配置:

# Root logger option
log4j.rootLogger=INFO, stdout

# Direct log messages 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{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

log4j.logger.com.ibatis=INFO
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=INFO
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=INFO
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=INFO
log4j.logger.java.sql=INFO
log4j.logger.java.sql.Connection=INFO
log4j.logger.java.sql.Statement=INFO
log4j.logger.java.sql.PreparedStatement=INFO
log4j.logger.java.sql.ResultSet=INFO

# Thymeleaf logger
log4j.logger.org.thymeleaf=ERROR
log4j.logger.org.thymeleaf.TemplateEngine.CONFIG=ERROR
log4j.logger.org.thymeleaf.TemplateEngine.TIMER=ERROR
log4j.logger.org.thymeleaf.TemplateEngine.PARSERCACHE=ERROR

我希望只有信息级别的日志，并且 Thymeleaf 配置为仅显示错误。但我仍然在 catalina.out 中获取此信息:

有什么线索吗？我知道这个错误可能很愚蠢，但我已经花了很长时间寻找答案 ;) 谢谢 :)

我在属性文件中没有看到任何会故意启用调试级别日志记录的内容。建议您返回到您的 catalina.out 文件并验证 log4j.properties 文件在启动时被解析且没有错误。还要查看 CATALINA_HOME/conf 文件夹中的 logging.properties 文件，并验证那里的所有日志记录都处于 CONFIG 或更低级别。
