Problem writing camel logs with log4j in a spring-boot application

[Ranabroto Ghosh]

Hi
I have a Spring-boot application with Apache Camel. All I am trying to
achieve here writing all logs(java log and also camel route level logs
using camel 'log' EIP) in a log file using log4j.



*My POM: *

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>

</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.16</version>
</dependency>


*LOG4J properties file: *
log4j.rootLogger=info, rollinglog, rollingerrorlog

log4j.logger.org.apache.camel=INFO

# File output configuration
log4j.appender.rollinglog=org.apache.log4j.DailyRollingFileAppender
log4j.appender.rollinglog.File=C://logs/testgateway.log
log4j.appender.rollinglog.Threshold=INFO

# roll over the file at the end of each day and append the date to the end
of the file
log4j.appender.rollinglog.DatePattern='.'yyyy-MM-dd

# Configure the layout for the log file
log4j.appender.rollinglog.layout=org.apache.log4j.PatternLayout
log4j.appender.rollinglog.layout.ConversionPattern=(%d) %p %t %c - %m%n

# File output configuration
log4j.appender.rollingerrorlog=org.apache.log4j.DailyRollingFileAppender
log4j.appender.rollingerrorlog.File=C://logs/ testgateway.log
log4j.appender.rollingerrorlog.Threshold=ERROR

# roll over the file at the end of each day and append the date to the end

log4j.appender.rollingerrorlog.DatePattern='.'yyyy-MM-dd

# Configure the layout for the log file
log4j.appender.rollingerrorlog.layout=org.apache.log4j.PatternLayout
log4j.appender.rollingerrorlog.layout.ConversionPattern=(%d) %p %t %c - %m%n


*My Camel route: *

<route id="test-route" autoStartup="true">
<from uri="restlet:/test"/>

<!-- Logs are getting printed correctly in expected log file from below
java method-->
<to uri="bean:sendMessage?method=test"/>

<!-- Logs are not getting printed in expected log file from below log EIP-->

<log message="HEADER: ${headers}"/>
</route>

So I am confused why camel log not getting printed from camel contexts
wjere java logs are working fine, could you please guide me what I am
missing here

Hi

Its probably more of a Spring Boot question how to configure its logging.
I suggest to study their documentation.

Camel uses the slf4j-api and that ought to work fine with SB.

Simple solution is use logback.xml file include in your spring boot
application that's all.

Yeah SB uses logback as the logger impl by default.
