configureGlobal on @SpringBootApplication fails #2473
Description
The following fails:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
@SpringBootApplication
public class HelloWebSecurityApplication {
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception {
// @formatter:off
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER");
// @formatter:on
}
public static void main(String[] args) {
SpringApplication.run(HelloWebSecurityApplication.class, args);
}
}We should allow Spring Security's Global Authentication to be configured from any class annotated with @EnableGlobalAuthentication, @EnableAutoConfiguration, or @SpringBootApplication. This can be done by adding the following:
@Configuration
@ConditionalOnClass(GlobalAuthenticationConfigurerAdapter.class)
public class BootGlobalAuthenticationConfiguration {
@Bean
public static BootGlobalAuthenticationConfigurationAdapter bootGlobalAuthenticationConfigurationAdapter(ApplicationContext context) {
return new BootGlobalAuthenticationConfigurationAdapter(context);
}
private static class BootGlobalAuthenticationConfigurationAdapter extends GlobalAuthenticationConfigurerAdapter {
private final ApplicationContext context;
private static final Log logger = LogFactory.getLog(BootGlobalAuthenticationConfiguration.class);
public BootGlobalAuthenticationConfigurationAdapter(ApplicationContext context) {
this.context = context;
}
@Override
public void init(AuthenticationManagerBuilder auth) {
Map<String, Object> beansWithAnnotation = context.getBeansWithAnnotation(EnableAutoConfiguration.class);
if(logger.isDebugEnabled()) {
logger.debug("Eagerly initializing " + beansWithAnnotation);
}
}
}
}
