Enable Spring Security Logging

Component Generator (JHipster)
#1

You can enable two types of logs:

1 - at programming time setting @EnableWebSecurity(debug = true) in the SecurityConfiguration.java (mainly about request data)
2 - at configuration time using the org.springframework.security logger. You can do it using all the means provided by spring boot, so for example adding the following bold lines into application-dev.yml

logging:
  level:
    ROOT: DEBUG
    io.github.jhipster: DEBUG
    com.mycompany.myapp: DEBUG
    **org:
        springframework:
          security: debug**
