Turning off hibernate logging console output

Try to set more reasonable logging level. Setting logging level to info means that only log event at info or higher level (warn, error and fatal) are logged, that is debug logging events are ignored.

log4j.logger.org.hibernate=info

or in XML version of log4j config file:

<logger name="org.hibernate">
  <level value="info"/> 
</logger>

See also log4j manual.

You can disabled the many of the outputs of hibernate setting this props of hibernate (hb configuration) a false:

hibernate.show_sql
hibernate.generate_statistics
hibernate.use_sql_comments

But if you want to disable all console info you must to set the logger level a NONE of FATAL of class org.hibernate like Juha say.

The first thing to do is to figure out which logging framework is actually used.

Many frameworks are already covered by other authors above. In case you are using Logback you can solve the problem by adding this logback.xml to your classpath:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <logger name="org.hibernate" level="WARN"/>
</configuration>

Further information: Logback Manual-Configuration

To disable printing hibernate queries in logs, just add this to your application.properties

spring.jpa.show-sql=false

There are several parts of hibernate logging you can control based on the logger hierarchy of the hibernate package (more on logger hierarchy here).

    <!-- Log everything in hibernate -->
    <Logger name="org.hibernate" level="info" additivity="false">
      <AppenderRef ref="Console" />
    </Logger>

    <!-- Log SQL statements -->
    <Logger name="org.hibernate.SQL" level="debug" additivity="false">
      <AppenderRef ref="Console" />
      <AppenderRef ref="File" />
    </Logger>

    <!-- Log JDBC bind parameters -->
    <Logger name="org.hibernate.type.descriptor.sql" level="trace" additivity="false">
      <AppenderRef ref="Console" />
      <AppenderRef ref="File" />
    </Logger>

The above was taken from here.

Additionally you could have the property show-sql:true in your configuration file since that supersedes the logging framework settings. More on that here.

I managed to stop by adding those 2 lines

log4j.logger.org.hibernate.orm.deprecation=error

log4j.logger.org.hibernate=error

Bellow is what my log4j.properties looks like, i just leave some commented lines explaining the log level

# Root logger option
#Level/rules TRACE < DEBUG < INFO < WARN < ERROR < FATAL.
#FATAL: shows messages at a FATAL level only
#ERROR: Shows messages classified as ERROR and FATAL
#WARNING: Shows messages classified as WARNING, ERROR, and FATAL
#INFO: Shows messages classified as INFO, WARNING, ERROR, and FATAL
#DEBUG: Shows messages classified as DEBUG, INFO, WARNING, ERROR, and FATAL
#TRACE : Shows messages classified as TRACE,DEBUG, INFO, WARNING, ERROR, and FATAL
#ALL : Shows messages classified as TRACE,DEBUG, INFO, WARNING, ERROR, and FATAL
#OFF : No log messages display


log4j.rootLogger=INFO, file, console

log4j.logger.main=DEBUG
log4j.logger.org.hibernate.orm.deprecation=error
log4j.logger.org.hibernate=error

In my case I had added the dependency

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>5.5.6.Final</version>
    </dependency>

which was not necessary. I removed it and everything works perfectly

The @DataJpaTest annotation from Spring Boot Test Auto-Configure enables SQL output by default. To disable SQL output when using that annotation in tests, change

@DataJpaTest
public class MyTestClass {
    ...
}

to

@DataJpaTest(showSql = false)
public class MyTestClass {
    ...
}
