Disable EnableGlobalMethodSecurity annotation

Question

Is there a way I can disable the global method security using the boolean securityEnabled from my config.properties? Any other approach?

@EnableWebSecurity 
@EnableGlobalMethodSecurity(securedEnabled=true) 
@PropertySource("classpath:config.properties")  
public class SecurityConfig 
  extends WebSecurityConfigurerAdapter {    

  @Value("${securityconfig.enabled}") 
  private boolean securityEnabled;

  ...

}

Answer 1

The easiest way to do this is:

• Extract method security to its own class
• Remove the securedEnabled attribute entirely
• Override the customMethodSecurityMetadataSource method and return the result based on the configured value.

For example:

@EnableWebSecurity
@Configuration
@PropertySource("classpath:config.properties")
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    ...
}

@EnableGlobalMethodSecurity
@Configuration
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {

    @Value("${securityconfig.enabled}")
    private boolean securityEnabled;

    protected MethodSecurityMetadataSource customMethodSecurityMetadataSource() {
        return securityEnabled ? new SecuredAnnotationSecurityMetadataSource() : null;
    }    
}

I've managed this by defining a Spring "securityDisabled" profile and conditionally applying security config based off that. I'm using Spring Boot 2.0.2. I believe this should work if not using Spring Boot and in previous versions of Spring Boot, but I have not tested. It's possible some tweaks may be required to property and class names because I know in Spring 2.0 some of that changed.

// In application.properties (could also based in via command line or environment variable)
spring.profiles.active=securityDisabled
// Or even with
spring.profiles.include=securityDisabled

Then my security config looks like this:

@Configuration
public class SecurityConfig {

  // When the securityDisabled profile is applied the following configuration gets used
  @Profile("securityDisabled")
  @EnableWebSecurity
  public class SecurityDisabledConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // Configure http as needed from Spring Security defaults when
        // NO security is desired
    }
  }

  // When the securityDisabled profile is NOT applied the following configuration gets used
  @Profile("!securityDisabled")
  @EnableGlobalMethodSecurity(prePostEnabled = true)
  @EnableWebSecurity
  public class SecurityEnabledConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // Configure http as needed from Spring Security defaults when
        // security is desired
    }
  }
}
