Hi I am getting confused with setting up old version of Sentry(ver 1.7.30) with current Spring Boot project(ver 1.5.7).
Here's my part of Gradle:
dependencies {
compile("org.springframework.boot:spring-boot-starter-web")
compile("org.springframework.boot:spring-boot-starter-logging")
compile("org.springframework.boot:spring-boot-starter-actuator")
...
implementation 'io.sentry:sentry-spring:1.7.30'
implementation 'io.sentry:sentry-logback:1.7.30'
}
application-local.yml
sentry:
dsn: https://dsnPath
logback-spring.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- sentry -->
<configuration>
<appender name="Sentry" class="io.sentry.logback.SentryAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>WARN</level>
</filter>
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="info">
<appender-ref ref="FILE"/>
<appender-ref ref="Sentry" />
</root>
</configuration>
When I run the project on local laptop, I can see some exception logs on console but they don't show up on Sentry. One thing I'm sure is..there's log4j2-spring.xml before I created logback-spring.xml file only for Sentry and this might be a problem?
(I followed the instruction on official page - https://docs.sentry.io/platforms/java/legacy/spring/ - and it didn't work. Maybe I made mistake regarding resolver.)
Thanks in advance!

I have been using the default spring logging configuration where I only specify filename in the application.properties file.
logging.file.name=app.log
But this by default appends logs when I start the application from cmd line "java -jar abc.jar"
I tried to search for the property which clears the file before starting application every time but couldn't find it. How should I clear the log file before starting the app?
Spring Boot uses Logback framework as as a default Logger.
You can use environnement variable via application.properties file to set some logging properties but logback xml configuration provides more powerfull features.
When a file in the classpath has one of the following names, Spring Boot will automatically load it over the default configuration:
logback-spring.xml
logback.xml
logback-spring.groovy
logback.groovy
So You can just put the code snippet below in src/main/resources/logback-spring.xml file
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="Console"
class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>
%black(%d{ISO8601}) %highlight(%-5level) [%blue(%t)] %yellow(%C{1.}): %msg%n%throwable
</Pattern>
</layout>
</appender>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>app.log</file>
<append>false</append>
<encoder>
<pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
</encoder>
</appender>
<!-- LOG everything at INFO level -->
<root level="info">
<appender-ref ref="FILE" />
<appender-ref ref="Console" />
</root>
</configuration>
The line <append>false</append> does the job.
if you wanna log more information than those avaible with the encoder pattern <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern> please check logback documention https://logback.qos.ch/manual/layouts.html#logback-access
One of my spring boot applications suddenly stopped working, after server restart. The application is failing to start, these are the messages from log file
ERROR o.s.boot.SpringApplication - Application startup failed
java.lang.IllegalStateException: Logback configuration error detected:

I tried setting the log parameters in the application properties file but still doesn't work, properties like logging.path, logging.file, logging.pattern.file
The application used to work fine, no code changes were made for last few months, but after server restart it stopped working, application works fine in my local machine.
For people that might still be looking for an answer. We were able to solve this by editing our logback-spring xml by removing:
<include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
and if present (it was in our file but not in the code posted in the question) remove:
<appender-ref ref="CONSOLE"/>
I want to print my logs of Spring Boot application, but I want to print my application logs in INFO. It is writing everything from server startup to stop.
I want to write logs in INFO, that I wrote into my application.
How to do it in Spring Boot?
Disable startup log messages by envoking .logStartupInfo(false) in your Application builder.
It should look like:
new SpringApplicationBuilder(ServiceConfiguration.class)
.logStartupInfo(false)
.run(args);
Please refer to this link for more clarity.
OR
Add logback.xml inside src/main/resources and the contents should be:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{dd-MM-yyyy HH:mm:ss.SSS} %magenta([%thread]) %highlight(%-5level) %logger{36}.%M - %msg%n</pattern>
</encoder>
</appender>
<root level="off">
<appender-ref ref="STDOUT" />
</root>
</configuration>

I have to put all the log data (i.e., debug, info, error) into mysql database instead of to file/console.
I read the spring boot documentation but I didn't see any configuration related to database for logging.
https://docs.spring.io/spring-boot/docs/current/reference/html/howto-logging.html
Also tried the following link but its also not working.
https://www.tutorialspoint.com/log4j/log4j_logging_database.htm
Can anyone help me to do this.
Thanks.
I read the spring boot documentation but I didn't see any
configuration related to database for logging.
Because spring boot hands off that functionality to logging framework (slf4j + logback/log4j etc). So you need to configure your logging framework accordingly using it's configuration file (eg: logback.xml, logback-spring.xml, logback.groovy etc). Default logging frameworks in Spring boot is slf4j+logback. So checkout how you can use DBAppender.
For Logback

Log to database with LogBack
https://medium.com/#chakrar27/storing-log-data-in-postgresql-using-logback-db-appender-292891a9918
1. create logback.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<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{5} - %msg%n
</pattern>
</encoder>
</appender>
<appender name="db" class="ch.qos.logback.classic.db.DBAppender">
<connectionSource
class="ch.qos.logback.core.db.DriverManagerConnectionSource">
<driverClass>org.postgresql.Driver</driverClass>
<url>jdbc:postgresql://localhost:5432/simple</url>
<user>postgres</user>
<password>root</password> <!-- no password -->
</connectionSource>
</appender>
<!-- the level of the root level is set to DEBUG by default. -->
<root level="TRACE">
<appender-ref ref="stdout" />
<appender-ref ref="db" />
</root>
</configuration>
2. Create the 3 tables
logging_event
logging_event_property
logging_event_exception
They must exist before DBAppender can be used
For Log4J
https://logging.apache.org/log4j/2.x/manual/appenders.html#JDBCAppender
For Log4J2
http://smasue.github.io/log4j2-spring-database-appender
As specified in title I'm using Maven, and Jetty. For logging using SLF4J and Logback. I have 'logback.xml' at 'src/main/resources'.
<configuration>
<appender name="STDOUT"
class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%-4relative [%thread] %-5level %class - %msg%n</pattern>
</layout>
</appender>
<appender name="FILE"
class="ch.qos.logback.core.FileAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%-4relative [%thread] %-5level %class - %msg%n</pattern>
</layout>
<File>myLog.log</File>
</appender>
<logger name="org.mortbay">
<level value="debug" />
</logger>
<root>
<level value="error" />
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
</configuration>
But my problem is its not creating the file 'myLog.log' if I run/debug the project. What's the solution to get the log file.
Is there any way to get the log file only with SLF4J?
Sorry! I misunderstood the usage of 'Logback'. I got solution from http://www.mail-archive.com/user#slf4j.org/msg00661.html
i.e.
It appears that you have misunderstood
the purpose of SLF4J. If you place
slf4j-jdk14-1.5.6.jar then slf4j-api
will bind with java.util.logging.
Logback will not be used. Only if you
place logback-core.jar and
logback-classic.jar on your class path
(but not slf4j-jdk14-1.5.6.jar) will
SLF4J API bind with logback. SLF4J
binds with one and only one underlying
logging API (per JVM launch).
HTH,
Thanks to Ceki Gulcu. Now I can able to get logs in my file.
If you are using JBoss 5.1 and you are having the same problem[logback not writing to file] then add the following in jboss-web.xml.
<class-loading>
<loader-repository>
com.hp:classloader=logback-slf4j
<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
</loader-repository>
</class-loading>
This should solve your problem.
