Docx4j gives me a bunch of messages like this
[AWT-EventQueue-0] INFO org.docx4j.model.listnumbering.Emulator -
How to turn that off?
The following log configuration gets loaded, but doesnt turns the logging off.
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %c{1} - %m%n"/>
</layout>
</appender>
<root>
<priority value ="OFF" />
</root>
</log4j:configuration>
Add the following line to your configuration:
<logger name="org.docx4j.model.listnumbering.Emulator">
<level value="ERROR" />
<appender-ref ref="console"/>
</logger>
This will configure log4j to log only ERROR messages originating from logger org.docx4j.model.listnumbering.Emulator. If you want to turn off INFO messages from all classes/packages under org.docx4j, use the following:
<logger name="org.docx4j" >
<level value="ERROR" />
<appender-ref ref="console"/>
</logger>

I'm using docx4j 8.3.2, logged by slf4j 1.7.30 + logback 1.2.3.
The annoying log messages disappeared after adding a logback.xml under src/main/resources. The logback.xml content:
<configuration>
<appender name="STDOUT"
class="ch.qos.logback.core.ConsoleAppender">
<!-- encoders are assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder
by default -->
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} %line - %msg%n
</pattern>
</encoder>
</appender>
<!-- docx4j loggers -->
<logger name="org.docx4j" level="ERROR" />
<root level="DEBUG">
<appender-ref ref="STDOUT" />
</root>

I'm setting up more complex logging then a simple console output. Logback writes logs really well via ConsoleAppender. But when I add extra RollbarAppender it does not work for it.
Here is an example of logback.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration >
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%highlight([%level]) - [%date] - [%logger] %msg%n</pattern>
</encoder>
</appender>
<appender name="ROLLBAR" class="com.rollbar.logback.RollbarAppender">
<accessToken>VERY_SECRET_TOKEN</accessToken>
<encoder>
<pattern>%highlight([%level]) - [%date] - [%logger] %msg%n</pattern>
</encoder>
</appender>
<logger name="akka" level="ERROR" additivity="false">
<appender-ref ref="ROLLBAR" />
</logger>
<logger name="slick" level="ERROR"/>
<root level="INFO">
<appender-ref ref="CONSOLE" />
</root>
</configuration>
Meanwhile this configuration works fine and sends logs to the 3rd party logging service, but doesn't write to the console :(
<?xml version="1.0" encoding="UTF-8"?>
<configuration >
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%highlight([%level]) - [%date] - [%logger] %msg%n</pattern>
</encoder>
</appender>
<appender name="ROLLBAR" class="com.rollbar.logback.RollbarAppender">
<accessToken>VERY_SECRET_TOKEN</accessToken>
<encoder>
<pattern>%highlight([%level]) - [%date] - [%logger] %msg%n</pattern>
</encoder>
</appender>
<logger name="akka" level="INFO" additivity="false">
<appender-ref ref="CONSOLE" />
</logger>
<logger name="slick" level="ERROR"/>
<root level="ERROR">
<appender-ref ref="ROLLBAR" />
</root>
</configuration>
So I'm confused. How to make logback work in this way:
INFO level events write to the console
ERROR level events write to the console + ROLLBAR
The solution was pretty simple. <filter> tag solved the issue: Its logging level overrides logging level of the <root> tag
<appender name="RollBar" class="com.rollbar.logback.RollbarAppender">
<accessToken> VERY_SECRET_TOKEN </accessToken>
<environment>PROD</environment>
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>ERROR</level>
</filter>
</appender>
...
<root level="INFO">
<appender-ref ref="CONSOLE" />
<appender-ref ref="RollBar" />
</root>
I am working on a Spring-MVC application in which I am using Jetty as our application server. I want to debug log a specific java class, but even after enabling log4j or slf4j, and adding files it's not working.
Finally, I created a war file, added to start log4j with this command java -jar start.jar --add-to-start=logging-log4j, which created a log4j.xml file in resources directory. In that log4j.xml, I added the class I want to debug, but no [DEBUG] entries are getting added.
Enabled modules :
log4j2-slf4j.mod
slf4j-log4j2.mod
slf4j-api.mod
logging-slf4j.mod
I have also tried their combinations and different loggings as documentation suggested.
log4j.xml present in resources directory of both IDE and Jetty.
<?xml version="1.0" encoding="UTF-8"?>

What am I doing wrong?
It seems that the problem is that you have only bridges and not log4j itself in the classpath.
As requested a simple logback.xml config file:
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- encoders are assigned the type
ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
</pattern>
</encoder>
</appender>
<logger name="test" level="DEBUG" />
<root level="INFO">
<appender-ref ref="STDOUT" />
</root>
</configuration>
I am new to java and need to place logs using slf4j, I need to put sensitive data logs into a different file.
Example:
package in.com.my.service.here
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.MDC;
public static void main( args[] ) {
Logger log = LoggerFactory.getLogger(POSServiceImpl.class);
log.info("log without MDC");
MDC.put('isEncrypted',"true");
log.info("log line 1");
log.info("log line 2");
log.info("log line 3");
MDC.clear();
log.info("log again without MDC");
}
Important: please provide the logback.xml configuration such that the logs under MDC are store in different file when isEncrypted value is true.
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true">
<timestamp key="bySecond" datePattern="yyyy-MM-dd_HHmmss" />
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{5} - %msg%n
</pattern>
</encoder>
</appender>
<appender name="ROLLING"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${log.folder}/terminal-${bySecond}.log</file>
<rollingPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>${log.folder}/Archive-%d{yyyy-MM-dd}.%i.log
</fileNamePattern>
<maxFileSize>10MB</maxFileSize>
<maxHistory>30</maxHistory>
<totalSizeCap>1GB</totalSizeCap>
</rollingPolicy>
<encoder>
<pattern>My ID [%X{myId}] %d{HH:mm:ss.SSS} [%thread]
%-5level %logger{5} - %msg%n</pattern>
</encoder>
</appender>
<logger name="in.com.my.service" level="debug"
additivity="false">
<appender-ref ref="ROLLING" />
<appender-ref ref="STDOUT" />
</logger>
<!-- By default, the level of the root level is set to DEBUG -->
<root level="info">
<appender-ref ref="ROLLING" />
<appender-ref ref="STDOUT" />
</root>
</configuration>
This looks like a candidate for Logback's SiftingAppender, javadoc. For example:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="SIFTER" class="ch.qos.logback.classic.sift.SiftingAppender">
<discriminator>
<key>encryptedStatus</key>
<defaultValue></defaultValue>
</discriminator>
<sift>
<appender name="FILE${encryptedStatus}" class="ch.qos.logback.core.FileAppender">
<file>File${encryptedStatus}.log</file>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>...</pattern>
</layout>
</appender>
</sift>
</appender>
<root level="ALL">
<appender-ref ref="SIFTER" />
</root>
</configuration>
The value of encryptedStatus will be substituted into the log file name. So, log events which contain the MDC value encryptedStatus=Sensitive will be written to FileSensitive.log and log events which do not contain a MDC attribute named encryptedStatus will be written to File.log.
You'll likely want to change the values of file name and the suffix for the sensitive files etc but the above extract shows you how you can direct log events to specific log files based on an MDC attribute.
Currently my Spring-boot application logs to a file named: myLog.log, this is working as intended, however I would like the log file to have a timestamp at the end of it and create a new file each time it is ran.
I have tried to implement this in my logback-test.xml file shown below, but it is just giving me the filename: myLog.log without a timestamp.
How can I fix this?
Logback-test.xml:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<include resource="org/springframework/boot/logging/logback/base.xml"/>
<logger name="org.springframework.web" level="INFO"/>
<!-- Send debug messages to System.out -->
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- By default, encoders are assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder -->
<encoder>
<pattern>%d{HH:mm:ss.SSS} - %msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>path/to/my/file/mylog.log</file>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>%d{yyyy-MM-dd_HH:mm:ss.SSS} - %msg%n</Pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<FileNamePattern>mylog.%i{yyyy-MM-dd_HH:mm:ss.SSS}}.log</FileNamePattern>
<MinIndex>1</MinIndex>
<MaxIndex>10</MaxIndex>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>2MB</MaxFileSize>
</triggeringPolicy>
</appender>
<logger name="com.my.package" level="INFO" additivity="false">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</logger>
<!-- By default, the level of the root level is set to DEBUG -->
<root level="INFO">
<appender-ref ref="STDOUT" />
</root>
</configuration>
You can define a variable like this:
<timestamp key="myTimestamp" datePattern="yyyy-MM-dd'_'HH-mm-ss.SSS"/>
(note: don't use colons in datePattern)
Then use it directly in your appender's file element:
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>path/to/my/file/mylog-${myTimestamp}.log</file>
...
</appender>
Or in a simple FileAppender:
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>path/to/my/file/mylog-${myTimestamp}.log</file>
<encoder>
<Pattern>%d{yyyy-MM-dd_HH:mm:ss.SSS} - %msg%n</Pattern>
</encoder>
</appender>
I am using logback api and have a logback.xml in my classpath which looks like this
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<configuration scan="true">
<contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
<resetJUL>true</resetJUL>

Now the rollback that i have implemented is not working in the production environment only. I wish to debug the same and hence want to put a trace for this logback api. Can anyone suggest what i might be doing wrong or what should i do to resolve this issue?
From Logback 1.0.4 you can use system property -Dlogback.debug=true to enable debugging of your Logback setup which will allow you to debug your configuration.
