Why is @EnableOAuth2Sso deprecated?

Question

Why is @EnableOAuth2Sso deprecated in Spring Security? That's the only reason why OAuth2 will work for me.

If I remove @EnableOAuth2Sso, then this will not work

@Configuration
@EnableOAuth2Client
@EnableOAuth2Sso <- Need to have this!
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        .csrf().disable()
        .authorizeRequests()
        .antMatchers("/Intranet/Bokning").authenticated()
        .antMatchers("/**", "/Intranet**").permitAll()
        .anyRequest().authenticated()
        .and().logout().logoutSuccessUrl("/").permitAll();
    }

}

Is there another solution?

Answer 1

This is a solution to latest Spring Security with Facebook OAuth2.0.

Security:

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Override
    public void configure(HttpSecurity http) throws Exception {

        http
        .csrf().disable()
        .authorizeRequests()
        .antMatchers("/Intranet/Bokning").authenticated() // Block this 
        .antMatchers("/**", "/Intranet**").permitAll() // Allow this for all
        .anyRequest().authenticated()
        .and().logout().logoutSuccessUrl("/").permitAll()
        .and()
        .oauth2Login();
    }
}

And appllication.yml

spring:
  security:
    oauth2:
      client:
        registration:
           facebook:
              clientId: myID
              clientSecret: mySecret
              accessTokenUri: https://graph.facebook.com/oauth/access_token
              userAuthorizationUri: https://www.facebook.com/dialog/oauth
              tokenName: oauth_token
              authenticationScheme: query
              clientAuthenticationScheme: form
              resource:
                 userInfoUri: https://graph.facebook.com/me

server:
  port: 8080

And pom.xml file:

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-security</artifactId>
