what is the use of auto-config=true in spring security

Question

what is the use of auto-config=true in spring security. In which scenario we should use this. what is the actual use of using auto-config=true ?

Answer 1

auto-config='true' means for the intercept-url pattern the spring security provides the default login screen

Answer 2

auto-config="true" is equivalent to:

<http>
    <form-login />
    <http-basic />
    <logout />
</http>

so it gives you a very basic security configuration to boot.
