如何將進程ID添加到LOG4J日誌文件？

Question

我目前在log4j中有以下模式佈局。我想將進程ID添加到日誌文件中。我該怎麼做？

log4j.appender.A1.layout=org.apache.log4j.PatternLayout 
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c - %m%n 

粘貼樣品日誌消息

Answer 1

沒有使用標準的Java類做它的方式。一般來說，進程ID不是以日誌級別附加在文件級別。而here就是這樣做的例子。

Answer 2

您應該使用MDC做

在配置文件：

log4j.appender.stdout.layout.ConversionPattern=%d{yyyy/MM/dd HH:mm:ss} %-5p (%c) %m%n %X{PID} 

%X{PID}用來匹配上下文值PID

然後，在代碼中，前記錄開始：

log4j 1.x

RuntimeMXBean rt = ManagementFactory.getRuntimeMXBean(); 
String pid = rt.getName(); 
MDC.put("PID", pid); 

的log4j 2.x的

RuntimeMXBean rt = ManagementFactory.getRuntimeMXBean(); 
String pid = rt.getName(); 
ThreadContext.put("PID", pid); 

Answer 3

隨着

以下方式，示出線程ID和類。如果你想看到的進程ID，可以檢查here

log4j.appender.SYSLOG.layout.conversionPattern=%-5p %d{ddMMyyyy HH:mm:ss.SSS} [%t:%c] %m%n 

我好不容易纔這樣做的，但我有幾個附加目的地，一個用於應用程序的每個部分，如下所示：

log4j.rootCategory=ERROR, SYSLOG2 
log4j.logger.com.myself.logic=DEBUG, SYSLOG 
log4j.logger.com.myself.database=DEBUG, SYSLOG3 
log4j.logger.com.myself.other=DEBUG, SYSLOG 

下面是生成的日誌的一些例子，來檢查，如果這是你需要什麼：
