extends Object

If there is a bean of type WebSecurityConfigurerAdapter, this adds the EnableWebSecurity annotation. This will make sure that the annotation is present with default security auto-configuration and also if the user adds custom security and forgets to add the annotation. If EnableWebSecurity has already been added or if a bean with name "springSecurityFilterChain" has been configured by the user, this will back-off.
