Java 如何使用log4j在syslog中整合多行日志

我正在使用rsyslog将我的var/log/message提供给一个工具。但是，正如您所看到的，异常出现在多行中（每行的时间戳不同），而不是作为一行记录。我希望它看起来像catalina.out消息。我有没有办法做到这一点。任何帮助都将不胜感激

catalina.out看起来像这样：

at java.lang.reflect.Method.invoke(Unknown Source)
at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:317)
at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:183)

at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:172)

var/log/message如下所示
