I am using .property file to create log file in specific path but i am creating single file using that. Following is my code of property file:
status = error dest = err name = PropertiesConfig property.filepath= /ap property.filename =${filepath}/ai.log property.filename1 =${filepath}/file1.log property.filename2 =${filepath}/file2.log filter.threshold.type = ThresholdFilter filter.threshold.level = debug appender.console.type = Console appender.console.name = STDOUT appender.console.layout.type = PatternLayout appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n appender.file.type = RollingFile appender.file.name = RootFile1 appender.file.fileName = ${filename} appender.file.filePattern = ${filepath}/%d{yyyyMMdd}/cpl.mw.%d{yyyyMMdd}.%i.log.gz appender.file.layout.type = PatternLayout #appender.file.layout.pattern = %d %p %C{1.} [%t] %m%n appender.file.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n appender.file.policies.type = Policies appender.file.policies.time.type = TimeBasedTriggeringPolicy appender.file.policies.time.interval = 1 appender.file.policies.time.modulate = true appender.file.policies.size.type = SizeBasedTriggeringPolicy appender.file.policies.size.size=50MB appender.file.strategy.type = DefaultRolloverStrategy appender.file.strategy.max = 20 appender.rolling1.type = RollingFile appender.rolling1.name = RollingFile1 appender.rolling1.fileName = ${filename1} appender.rolling1.filePattern = ${filepath}/%d{yyyyMMdd}/cpl.mw.%d{yyyyMMdd}.%i.log.gz appender.rolling1.layout.type = PatternLayout #appender.rolling1.layout.pattern = %d %p %C{1.} [%t] %m%n appender.rolling1.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n appender.rolling1.policies.type = Policies appender.rolling1.policies.time.type = TimeBasedTriggeringPolicy appender.rolling1.policies.time.interval = 1 appender.rolling1.policies.time.modulate = true appender.rolling1.policies.size.type = SizeBasedTriggeringPolicy appender.rolling1.policies.size.size=50MB appender.rolling1.strategy.type = DefaultRolloverStrategy appender.rolling1.strategy.max = 20 appender.rolling2.type = RollingFile appender.rolling2.name = RollingFile2 appender.rolling2.fileName = ${filename2} appender.rolling2.filePattern = ${filepath}/%d{yyyyMMdd}/cpl.mw.%d{yyyyMMdd}.%i.log.gz appender.rolling2.layout.type = PatternLayout appender.rolling2.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n appender.rolling2.policies.type = Policies appender.rolling2.policies.time.type = TimeBasedTriggeringPolicy appender.rolling2.policies.time.interval = 1 appender.rolling2.policies.time.modulate = true appender.rolling2.policies.size.type = SizeBasedTriggeringPolicy appender.rolling2.policies.size.size=50MB appender.rolling2.strategy.type = DefaultRolloverStrategy appender.rolling2.strategy.max = 20 loggers logger.name=file1 logger.level = debug logger.additivity = true logger.appenderRefs = rolling1,stdout logger.appenderRefs.level = debug logger.appenderRef.rolling1.ref = RollingFile1 logger.appenderRef.stdout.ref = STDOUT logger.name=file2 logger.level = debug logger.additivity = true logger.appenderRefs = rolling2 logger.appenderRefs.level = debug logger.appenderRef.rolling2.ref = RollingFile2 above code is of my xyz.properties file i want to create multiple logs using this configuration file.My property configuration file create multiple file but not put different different logs in log files.I call this from JAVA using below code:
private static final Logger logCommon = LogManager.getLogger("file1"); private static final Logger logAnalytics = LogManager.getLogger("file2"); public static void main(String[] args) throws Exception { logCommon.info ("file1 Need it save into commons.log file"); logAnalytics.info ("file2 Only save into analytics.log file"); } 2018-01-22 12:52:23 INFO file2:301 - file2 Only save into analytics.log file log put in both log files.

Please set additivity=false for both named loggers.
Also, add a root logger configuration to tell Log4j2 where to send the logging calls other than the “file1” and “file2” loggers:
rootLogger.level = info rootLogger.appenderRef.stdout.ref = STDOUT Also, give your named loggers a unique prefix:
logger.aaa.name = file1 logger.aaa.additivity = false logger.aaa.level = debug logger.aaa.appenderRef.rrr.ref = RollingFile1 logger.bbb.name = file2 logger.bbb.additivity = false logger.bbb.level = debug logger.bbb.appenderRef.sss.ref = RollingFile2 Use below configuration and call addLogger() whenever you want to use with fully qualified path
public static void addLogger(String parentPath) throws SecurityException, IOException { try { InputStream in = ConfiguratorHelper.class.getResourceAsStream("/resources/mylogging.properties"); LogManager.getLogManager().readConfiguration(in); } catch (SecurityException | IOException e1) { e1.printStackTrace(); } logger.setLevel(Level.FINE); logger.addHandler(new ConsoleHandler()); logger.addHandler(new MyHandler()); try { //FileHandler file name with max size and number of log files limit Handler fileHandler = new FileHandler(path, 1000000, 10); fileHandler.setFormatter(new MyFormatter()); fileHandler.setFilter(new MyFilter()); logger.addHandler(fileHandler); logger.log(Level.CONFIG, "Config data"); } catch (SecurityException | IOException e) { e.printStackTrace(); } } public class MyFilter implements Filter { @Override public boolean isLoggable(LogRecord log) { //don't log CONFIG logs in file if(log.getLevel() == Level.CONFIG) return false; return true; } } public class MyFormatter extends Formatter { @Override public String format(LogRecord record) { return record.getThreadID()+"::"+record.getSourceClassName()+"::" +record.getSourceMethodName()+"::" +new Date(record.getMillis())+"::" +record.getMessage()+"\n"; } } public class MyHandler extends StreamHandler { @Override public void publish(LogRecord record) { //add own logic to publish super.publish(record); } @Override public void flush() { super.flush(); } @Override public void close() throws SecurityException { super.close(); } }
