Can't avoid hibernate logging SQL to console with Spring Boot and Logback

Question

My Spring Boot application keeps showing Hibernate queries in the console despite having configured Hibernate's specific logging with Logback as follows:

<appender name="HIBERNATE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${LOGDIR}/hibernate.log</file>
    <encoder>
        <pattern>%d{yyyy-MM-dd HH:mm:ss} - %msg%n</pattern>
    </encoder>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${LOGDIR}/hibernate.log.%d</fileNamePattern>
    </rollingPolicy>
</appender>

<logger name="org.hibernate" additivity="false">
    <appender-ref ref="HIBERNATE"/>
</logger>

<logger name="org.hibernate.SQL" additivity="false">
    <appender-ref ref="HIBERNATE"/>
</logger>

<logger name="org.hibernate.type.descriptor.sql" additivity="false">
    <appender-ref ref="HIBERNATE"/>
</logger>

It does send Hibernate's logs, including queries, to the file hibernate.log . But I would also like to avoid the queries in the console, which I think should be happening with this configuration.

What am I missing?

Answer 1

If you set the hibernate.show_sql to true , Hibernate will simply print the SQL statement to the console (not to be confused with logging under org.hibernate.SQL ). SqlStatementLogger is responsible for logging the SQL statements and its logStatement looks like:

public void logStatement(String statement, Formatter formatter) {
    if ( format ) {
        if ( logToStdout || LOG.isDebugEnabled() ) {
            statement = formatter.format( statement );
        }
    }
    LOG.debug( statement );
    if ( logToStdout ) {
        System.out.println( "Hibernate: " + statement );
    }
}

So, if you do not want to see the queries on the console, just disable the hibernate.show_sql by setting it to false or just removing it altogether. In Spring Boot, just add this to your application.properties :

spring.jpa.show-sql=false

I just wanted to share that I just noticed there is another setting which could cause org.hibernate.SQL to debug in Spring Boot JUnit tests, though you might have set

spring.jpa.show-sql=false 

and

spring.jpa.properties.hibernate.show_sql=false

...

If you set

debug=true

in your Spring application*.properties file!

This one set to true will override the show-sql setting and set it to true.

You basically need to set 2 properties to false.

If you are using Spring boot , then set up in Application.properties as below

spring.jpa.properties.hibernate.generate_statistics=false
spring.jpa.properties.hibernate.show_sql=false

And If you are using hibernate.cfg.xml, then set up as below

<property name="hibernate.generate_statistics">false</property>
<property name="show_sql">false</property>

如果有人尝试了以上所有方法但仍有问题，请尝试设置属性：

logging.level.org.hibernate.SQL=OFF

Answer 5

My application is a spring-boot one,

For some reason in my case the property 'spring.jpa.show-sql=false' didn't work. I could see the sql with the bind values keep on printing the queries in the console/log.

It is resolved by changing the root level to error like below

<root level="ERROR"> <appender-ref ref="STDOUT"/> </root>

Though we change log level to error in the root, we still can print our package/application logs in the info mode my using the separate loggers like below

<logger name="com.application.code" level="INFO"> <appender-ref ref="FILE"/> <appender-ref ref="ERR_FILE"/> </logger>

putting here so it might help someone.

Thanks
