Property 'security.basic.enabled' is Deprecated: The security auto-configuration is no longer customizable

Question

I am working on Spring Cloud project using the spring-boot-starter-parent version 2.0.1.RELEASE.

I am getting below warning, look like

Property 'security.basic.enabled' is Deprecated: The security auto-configuration is no longer customizable. Provide your own WebSecurityConfigurer bean instead.

security: basic: enabled: false is disabled in spring security latest version.

Could you please guide me what should I used instead ?

Here is the my test class.

@RunWith(SpringRunner.class)
@SpringBootTest
public class PluralsightSpringcloudM2ConfigserverGitApplicationTests {

    @Test
    public void contextLoads() {
    }

}

and

Its nothing to do with the other question

Answer 1

Spring Boot 2.0 changed its auto configuration (including some properties) and has now a single behavior that backs off as soon as you add your own WebSecurityConfigurerAdapter. The default configuration looks like

protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .anyRequest().authenticated()
            .and()
        .formLogin()
            .and()
        .httpBasic();
}

A single user with a generated password is configured by default. To customize this user use the properties under spring.security.user.

spring.security.user.name=user # Default user name.
spring.security.user.password= # Password for the default user name.
spring.security.user.roles= # Granted roles for the default user name.

The following properties have been removed as of Spring Boot 2:

security.basic.authorize-mode
security.basic.enabled
security.basic.path
security.basic.realm
security.enable-csrf
security.headers.cache
security.headers.content-security-policy
security.headers.content-security-policy-mode
security.headers.content-type
security.headers.frame
security.headers.hsts
security.headers.xss
security.ignored
security.require-ssl
security.sessions

Replacements (if existing) can be found here: Appendix A. Common application properties

To be clear: If you create a custom WebSecurityConfigurerAdapter the default security configuration will be replaced with your custom configuration:

@EnableWebSecurity
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // For example: Use only Http Basic and not form login.
        http
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .httpBasic();
    }
}
