M Sazzadul Hoque updated LOG4J2-1963:
-------------------------------------
Description:
Consider my following code:
{quote}{code:java}
import org.apache.logging.log4j.LogManager;
public class TestClass {
public static void main(String[] args) {
LogManager.getLogger().info("message(1)");
LogManager.getLogger().info("message(2)");
LogManager.getLogger().info("message(3)");
LogManager.getLogger().info("message(4)");
}
}
{code}{quote}
If I use following log4j2.xml
{quote}{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn">
<Appenders>
<RollingFile name="ROLLING" fileName="test/Log.log"
filePattern="test/Log-%i.log" >
<PatternLayout pattern="%d %-5p %C %t (%F:%L) - %m%n" />
<SizeBasedTriggeringPolicy size="1B" />
</RollingFile>
</Appenders>
<Loggers>
<Root level="all">
<AppenderRef ref="ROLLING" />
</Root>
</Loggers>
</Configuration>
{code}{quote}
I get following 4 files (as expected) containing all logs:
{quote}Log-1.log Log-2.log Log-3.log Log.log{quote}
However, if I use either parentheses "()" or square braces "[]" in filePattern,
I get only 2 file containing last two logs and first two logs are lost.
filePattern="test/Log(%i).log" generates:
{quote}Log(1).log Log.log{quote}
filePattern="test/(Log)%i.log" generates:
{quote}(Log)1.log Log.log{quote}
filePattern="test/Log[%i].log" generates:
{quote}Log[1].log Log.log{quote}
filePattern="test/[Log]%i.log" generates:
{quote}[Log]1.log Log.log{quote}
Moreover, usage of curly braces creates error.
filePattern="test/Log\{%i\}.log" creates following error 4 times:
