# How to use authenticationManager Bean in 5.7.1
> 참고 : https://spring.io/blog/2022/02/21/spring-security-without-the-websecurityconfigureradapter
### Question
Is there any example how can I expose the AuthenticationManager bean? Previously I could do this by extending WebSecurityConfigurerAdapter and then creating the following method in my security config:
```
@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
```
### Answer
The following solution solved the issue for me.
```
@Bean
public AuthenticationManager authenticationManager(AuthenticationConfiguration authenticationConfiguration) throws Exception {
return authenticationConfiguration.getAuthenticationManager();
}
```
# Profile
Set ```application.yml``` to use ```.dev.env``` file
```yaml
spring:
config:
import: optional:file:.dev.env[.properties]
```
