'Duplicate tomcat logs

Have spring boot app with only one dependency spring-boot-starter web and want to see tomcat logs for that i added to logging.properties that

handlers = 1catalina.org.apache.juli.FileHandler, \
           2localhost.org.apache.juli.FileHandler, \
           3manager.org.apache.juli.FileHandler, \
           java.util.logging.ConsoleHandler

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

############################################################
# Handler specific properties.
# Describes specific configuration info for Handlers.
############################################################

1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.
1catalina.org.apache.juli.FileHandler.maxDays = 90
1catalina.org.apache.juli.FileHandler.encoding = UTF-8

2localhost.org.apache.juli.FileHandler.level = FINE
2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
2localhost.org.apache.juli.FileHandler.prefix = localhost.
2localhost.org.apache.juli.FileHandler.maxDays = 90
2localhost.org.apache.juli.FileHandler.encoding = UTF-8

3manager.org.apache.juli.FileHandler.level = FINE
3manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
3manager.org.apache.juli.FileHandler.prefix = manager.
3manager.org.apache.juli.FileHandler.bufferSize = 16384
3manager.org.apache.juli.FileHandler.maxDays = 90
3manager.org.apache.juli.FileHandler.encoding = UTF-8

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.OneLineFormatter
java.util.logging.ConsoleHandler.encoding = UTF-8

############################################################
# Facility specific properties.
# Provides extra control for each logger.
############################################################

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = \
   2localhost.org.apache.juli.FileHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].handlers = \
   3manager.org.apache.juli.FileHandler

# For example, set the org.apache.catalina.util.LifecycleBase logger to log
# each component that extends LifecycleBase changing state:
#org.apache.catalina.util.LifecycleBase.level = FINE

and start my jar with -Djava.util.logging.config.file=PATH_TO_LOGGING_PROPERTIES and all tomcat logs are duplicate

org.apache.coyote.AbstractProtocol init Initializing ProtocolHandler ["http-nio-8080"] [thread-missing] org.apache.coyote.AbstractProtocol init Initializing ProtocolHandler ["http-nio-8080"] [thread-missing] org.apache.catalina.core.StandardService startInternal Starting service [Tomcat] [thread-missing] org.apache.catalina.core.StandardService startInternal Starting service [Tomcat]

how that can be resolved?

Solution 1:[1]

The format of the default Tomcat configuration file is not supported by the default java.util.logging LogManager. In the standard LogManager the properties .handlers and handlers are synonyms, hence the double console handler.

To use the default Tomcat configuration file, you need to use the ClassLoaderLogManager (cf. Tomcat documentation) by using:

-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
