How to log SQL statements in Spring Boot?

try using this in your properties file:

logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE

This works for stdout too:

spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.use_sql_comments=true
spring.jpa.properties.hibernate.format_sql=true

To log values:

logging.level.org.hibernate.type=trace

Just add this to application.properties.

This works for me (YAML):

spring:
  jpa:
    properties:
      hibernate:
        show_sql: true
        format_sql: true
logging:
  level:
    org:
      hibernate:
        type: trace
