How to disable hibernate sql logs in log4j2 with spring boot? - spring-boot

Question

We have an application written in spring boot. We are using Hibernate search 6 to fetch data from elasticsearch.
We have configured log4j2 as below:
log4j2.xml
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO" packages="net.xxxx.logging">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
</Console>
<Console name="ConsoleDev" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss} [%t]
%highlight{%level}{FATAL=bg_red, ERROR=red, WARN=yellow, INFO=green, DEBUG=blue} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<Logger name="com.zaxxer.hikari" level="${env:LOG_LEVEL_HIKARI:-INFO}" additivity="false" >
<AppenderRef ref="${env:LOG_CONSOLE:-Console}" />
</Logger>
<Logger name="org.hibernate" level="INFO" additivity="false" >
<AppenderRef ref="${env:LOG_CONSOLE:-Console}" />
</Logger>
<Logger name="org.hibernate.search.fulltext_query" level="INFO" additivity="false" >
<AppenderRef ref="${env:LOG_CONSOLE:-Console}" />
</Logger>
<Logger name="org.springframework" level="${env:LOG_LEVEL_SPRING:-INFO}" additivity="false" >
<AppenderRef ref="${env:LOG_CONSOLE:-Console}" />
</Logger>
<Logger name="org.springframework.ldap" level="${env:LOG_LEVEL_LDAP:-INFO}" additivity="false" >
<AppenderRef ref="${env:LOG_CONSOLE:-Console}" />
</Logger>
<Root level="INFO" includeLocation="false">
<AppenderRef ref="${env:LOG_CONSOLE:-Console}" />
</Root>
</Loggers>
</Configuration>
application.yaml:
spring:

jpa:
show-sql: true

We want to show hibernet sql queries logs show in debug mode only(in local environment) not in production build environment.
We tried by setting show_sql= false in application.yaml file but it disable logs on local and prod both environment. We want to enable to log sql queries in local environment.

Answer 1

You can use Profiles from spring boot spring profiles. The best way to get what you expected.

Answer 2

You can use Spring Profile for segregation between your Local and Production environment. Create two different copies of application.yml file like - application-dev.yml and application-prod.yml. Here in application-dev.yml you can enable the hibernate logs with show_sql= true while in another file application-prod.yml you can disable it show_sql= false.
You will have to create an environment variable SPRING_PROFILES_ACTIVE for picking files depending on your instance. Suppose your instance is development then you need to set this variable to dev otherwise it would be prod.
To switch profiles you can use one of the following options:
JVM property : -Dspring.profiles.active=dev
Command line switch: --spring.profiles.active=dev
Property file : spring.profiles.active=dev

Answer 3

The easiest way is to use a spring profile like this:
In your application.yml you configure the active profile depending on which branches you are in. If you are in dev it will take the properties of application-dev and if you are in prod of application-prod
application.yml
spring:
profiles:
active: prod #dev #staging
application-dev
liquibase.enabled: false
jpa:
show-sql: true
properties:
hibernate:
format_sql: false
dialect: org.hibernate.dialect.SQLServer2012Dialect
generate_statistics: false
search:
enabled: true
backend:
type: elasticsearch
dynamic_mapping: true
uris: ${ELASTIC_SEARCH_URL}
aws:
region: us-west-2
signing.enabled: true
application-prod
liquibase.enabled: false
jpa:
show-sql: false
properties:
hibernate:
format_sql: false
dialect: org.hibernate.dialect.SQLServer2012Dialect
generate_statistics: false
search:
enabled: true
backend:
type: elasticsearch
dynamic_mapping: true
uris: ${ELASTIC_SEARCH_URL}
aws:
region: us-west-2
signing.enabled: true
You can even optimize more using enviroment variables in your properties.
jpa:
show-sql: ${SHOW_SQL}
properties:
hibernate:
format_sql: ${FORMAT_SQL}
