Log4j 不打印完整的堆栈跟踪

Question

我检查了SO中的所有答案。但是 none 确实帮助了我。

我的 Log4j 属性文件

log4j.rootLogger=debug,console,file

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d %5p [%t] (%F:%L) - %m%n

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=eseries.log
log4j.appender.file.MaxFileSize=1KB
log4j.appender.file.layout=org.apache.log4j.EnhancedPatternLayout
log4j.appender.file.layout.ConversionPattern=%d %5p [%t] (%F:%L) - %m%n %throwable{short}

我的log4j版本

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.11</version>
  </dependency>

登录格式

    logger.error("*****Error Id is:"+errorId+"\t" , e);

我得到了什么

我刚刚在日志中收到 e.getMessage()。不是完整的日志跟踪。

有什么建议吗？

Answer 1

这是因为您的转化模式

 log4j.appender.file.layout.ConversionPattern=%d %5p [%t] (%F:%L) - %m%n %throwable{short}

此处摘自ThrowableInformationPatternConverter

Outputs the ThrowableInformation portion of the LoggingEvent. By default, outputs the full stack trace.

%throwable{none} or %throwable{0} suppresses the stack trace.

%throwable{short} or %throwable{1} outputs just the first line.

%throwable{n} will output n lines for a positive integer or drop the last -n lines for a negative integer.

您需要删除 %throwable{short} 才能查看完整的堆栈跟踪
