I add hibernate-validator(6.0.9.Final) to my spring (not spring boot) maven project and work perfectly, but cause lot of(~3000 row) DEBUG log. How to off this log?
I tried these, but didn't work:
logging.level.org.hibernate=info
log4j.logger.org.hibernate=info
The log level of Hibernate Validator is (obviously) not DEBUG by default so you must have something in your application classpath setting the log level to DEBUG.
Hibernate Validator is using JBoss Logging which uses log4j under the hood so log4j.logger.org.hibernate.validator=info in your log4j.properties should work.
But considering it shouldn't have been set to DEBUG in the first place, I'm wondering if you have something in your classpath overriding your log configuration.
I suspect either you or a dependency have enabled DEBUG logging for org.hibernate to see the queries or something similar and this is this setting you should find and remove.
Set the log4j properties as
log4j.logger.org.hibernate.validator=info
also set the show_sql =false to avoid the query printing on the console.

I would like to change the logging level of my Quarkus application.
How can I do that either from the configuration file or at runtime?
The property that controls the root logging level is quarkus.log.level (and defaults to INFO).
This property can be set either in application.properties or can be overridden at runtime using -Dquarkus.log.level=DEBUG.
You can also specify more fine grained logging using quarkus.log.category.
For example for RESTEasy you could set:
quarkus.log.category."org.jboss.resteasy".level=DEBUG
For more information about logging in Quarkus, please check this guide.
I am setup to use logback with my SpringBoot application and everything is running fine and dandy.
I noticed a property called logging.path in the application.properties file which sets the value for ${LOG_PATH} in logback.xml. How does it do it?
I went through the SpringBoot logging documentation.
Any documentation I could find on property placeholder configurer
Yet I don't understand how logging.path could pass the value for ${LOG_PATH}. Though not a killer issue, I would like to know how this mapping is made.
The magic is spring will transfter logging.path into System propeties LOG_PATH.
Description from spring doc:
To help with the customization some other properties are transferred from the Spring Environment to System properties:
And it also says:
All the logging systems supported can consult System properties when parsing their configuration files. See the default configurations in spring-boot.jar for examples.
Details:
https://docs.spring.io/spring-boot/docs/1.5.6.RELEASE/reference/htmlsingle/#boot-features-custom-log-configuration
For more recent versions of Spring Boot, such as 2.5.x, the logging.file.path maps to LOG_PATH.
I hope you can solve this very mysterious puzzle!
After migrating to Java8 and Tomcat8, the logging info on the servers is ok, but there is no logging information on the developer laptops. Adding Spring-boot-starter-log4j2 there is logging info on the laptops but NOT on the servers. How come? How to fix?
In the parent.pom both the dependencies slf4j-api, the slf4j-log4j binding and the 'slf4j : jcl-over-slf4j' are used. In the project there are no log4j.properites files. In all places where spring boot is used, the spring-boot-starter-logging is excluded.
Scenario 1:
On laptops - the SLF4J combination produces NO logging. I guess that is because there are no log4j.properties files. On the servers this combination shows logging. How can this be? Can there be a provided Tomcat configuration that allows this logging?
Scenario 2:
When I add the spring-boot-starter-log4j2, then I get logging on my laptop. On the server there is no logging at all.
You can define general logging settings in your tomcat environment. This is for example shown in this article.
In short: (1) add an extra library and (2) add a default log4j.properties file.
I have a Spring boot application which use logback.xml for logging configurations.I am looking for options to dynamically change log level.
For instance if I have deployed an app with loglevel as ERROR,Let say I want to change this to INFO but I don't want to redeploy/restart my JVM.
Is there any possibility we can configure logback.xml like config server to achieve this
You can configure Logback to Automatically reloading configuration file upon modification
Yes, this is quite possible. Expose a rest endpoint where you supply the className and log level. With slf4j you can get the LoggerContext and change the level.
LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
context.getLogger(className).setLevel(Level.valueOf(level));
Apache Commons logging and others have similar features.
If you are using spring cloud then you can have this in your yml file
logging:
level:
root: INFO
Then you can change it and refresh the configuration using actuator refresh to fetch new configuration changes no need to restart the service.
Also if you need some sort of UI to do this stuff you can explore the Spring-cloud-dashboard It is pretty cool and uses the features from the actuator to do and show you a lot of stuff not only changing log levels.
Is there a way to disable Spring boot logs and print only the logs which i give in the program using logger.info or logger.debug statements. I mean i want only the log statements which i had given in the program to be logged and nothing else. I use the default logging system given by spring boot. If required i can change to log4j or log4j2 as well. Using spring-boot version 1.2.7.
In other way, putting forward , like logging.level.org.springframework can be used to log spring related logs ,is there a way like logging.level.applicationlevel to get application(Java logger statement) logs alone
You can configure your logging in your application.properties like below:
logging.level.com.myapp.packagename=INFO
logging.level.org.springframework=ERROR
INFO means it will print logging of classes in your package and all sub package at INFO/ERROR/WARN level, while for spring related classes only print if there are ERROR level logging.
You can configure logging properties as follows:
logging.level.* = ERROR
logging.level.package_name=DEBUG
Example:
logging.level.com.example.controller=DEBUG
So classes under com.example.controller package will be logged, others only on error will be logged.
I hope this helped!!
