Show Sql in Jhipster 4.4.1 - spring-boot

Question

I added a new connection to my Jhipster application:
data:
mongodb:
uri: mongodb://localhost:27017
database: crm
datasources:
elser:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql://localhost:5432/elser
name: elser
username: elser
password: elser
I want to see in the sql logs that my connection to Postgres generates.
I have tested by adding the following code in 'application-dev.yml':
jpa:
properties:
hibernate:
show_sql: true
format_sql: true
or:
jpa:
show_sql: true
format_sql: true
But neither option worked for me.
Can somebody help me.
Thank you

According to spring docs setting spring.jpa.show-sql=true should do the trick.
Have you checked if it appears in stdout?
From the spring boot docs:
# JPA (JpaBaseConfiguration, HibernateJpaAutoConfiguration)
spring.data.jpa.repositories.enabled=true # Enable JPA repositories.
spring.jpa.database= # Target database to operate on, auto-detected by default. Can be alternatively set using the "databasePlatform" property.
spring.jpa.database-platform= # Name of the target database to operate on, auto-detected by default. Can be alternatively set using the "Database" enum.
spring.jpa.generate-ddl=false # Initialize the schema on startup.
spring.jpa.hibernate.ddl-auto= # DDL mode. This is actually a shortcut for the "hibernate.hbm2ddl.auto" property. Default to "create-drop" when using an embedded database, "none" otherwise.
spring.jpa.hibernate.naming.implicit-strategy= # Hibernate 5 implicit naming strategy fully qualified name.
spring.jpa.hibernate.naming.physical-strategy= # Hibernate 5 physical naming strategy fully qualified name.
spring.jpa.hibernate.naming.strategy= # Hibernate 4 naming strategy fully qualified name. Not supported with Hibernate 5.
spring.jpa.hibernate.use-new-id-generator-mappings= # Use Hibernate's newer IdentifierGenerator for AUTO, TABLE and SEQUENCE.
spring.jpa.open-in-view=true # Register OpenEntityManagerInViewInterceptor. Binds a JPA EntityManager to the thread for the entire processing of the request.
spring.jpa.properties.*= # Additional native properties to set on the JPA provider.
spring.jpa.show-sql=false # Enable logging of SQL statements.
