Spring Boot 2.0 disable default security

I want to use Spring Security for JWT authentication. But it comes with default authentication. I am trying to disable it, but the old approach of doing this - disabling it through application.properties - is deprecated in 2.0.

This is what I tried:

@Configuration
public class StackWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.httpBasic().disable();
        // http.authorizeRequests().anyRequest().permitAll(); // Also doesn't work.
    }
}

How can I simply disable basic security?

UPDATE
It might be nice to know that I am not using web mvc but web flux.

Screenshot:

According to the new updates in Spring 2.0, if Spring Security is on the classpath, Spring Boot will add @EnableWebSecurity.So adding entries to the application.properties ain't gonna work (i.e it is no longer customizable that way). For more information visit the official website Security changes in Spring Boot 2.0

Albeit not sure about your requirement exactly, I could think of one workaround like the following:-

@Configuration
@EnableWebSecurity
public class SecurityConfiguration  extends WebSecurityConfigurerAdapter{
	@Override
	protected void configure(HttpSecurity http) throws Exception{
		http.authorizeRequests().antMatchers("/").permitAll();
	}
}

Hope this helps.

From Spring Boot 2.1 on, if you include spring-boot-actuator, it does not suffice anymore to only exclude SecurityAutoconfiguration, you also need to exclude ManagementWebSecurityAutoConfiguration, like so:

@SpringBootApplication(exclude = { SecurityAutoConfiguration.class, ManagementWebSecurityAutoConfiguration.class })

According to the reference documentation, the Security configuration for allowing all requests with WebFlux should look like this:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.web.server.SecurityWebFilterChain;

@Configuration
public class SecurityConfig {
	
	@Bean
	public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
		http.authorizeExchange().anyExchange().permitAll();
		return http.build();
	}
}

This worked for me:

@Configuration
public class SecurityConfig  extends WebSecurityConfigurerAdapter {

	@Override
	protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests().anyRequest().permitAll();
    }
}

You can add/modify the following to your Application class:

@SpringBootApplication(exclude = { SecurityAutoConfiguration.class })
public class MyApplication {

}

Adding some fresh answer, I assume all use actuator, if not I'd bet one class exclusion should be sufficient, I managed to disable through properties:

spring:
  autoconfigure:
    exclude: ${spring.autoconfigure.sac}, ${spring.autoconfigure.mwsas}
    sac: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration
    mwsas: org.springframework.boot.actuate.autoconfigure.security.servlet.ManagementWebSecurityAutoConfiguration

I've referenced two auto-config classes through property to keep the length intact (note that IntelliJ Ultimate will cry if you reference it like that as it has no clue what are these placeholder values and if they are actually legit classes, so inline if that annoys you).

Application however does not fail to start as claimed by:

https://www.baeldung.com/spring-boot-security-autoconfiguration

if you just disable SecurityAutoConfiguration

If it did work, you will stop seeing auto generated password and it is a little bit less confusing than the accepted answer, as dev reading the log won't get confused by generated password for basic auth while security allows all.

Why just disabling main auto config class isn't enough is because of this fella:

@Configuration
class ManagementWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

	@Override
	protected void configure(HttpSecurity http) throws Exception {
		http.authorizeRequests()
				.requestMatchers(
						EndpointRequest.to(HealthEndpoint.class, InfoEndpoint.class))
				.permitAll().anyRequest().authenticated().and().formLogin().and()
				.httpBasic();
	}

}

There was tons of work made to split actuator and security config which confused us all, now its more straightforward but artifacts like these still exist. Spring devs will correct me if I am wrong :-).

If anyone is struggling with this in a WebFlux based application, or a Spring Cloud Gateway application, the below worked for me:

@EnableWebFluxSecurity
public class InsecurityConfiguration {
    // @formatter:off
    @Bean
    public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
         http
              .authorizeExchange()
                   .anyExchange().permitAll();
         return http.build();
    }
}

I think what you are looking for is to override the default authentication entry point which is set to BasicAuthenticationEntryPoint.

This entrypoint adds the

> "WWW-Authenticate": "Basic realm=..."

header that tells your browser to use Basic Auth.

If you're extending WebSecurityConfigurerAdapter, you can pass in true to the super constructor to disable the defaults.
You may need to provide other beans if you do this.

	/**
	 * Creates an instance which allows specifying if the default configuration should be
	 * enabled. Disabling the default configuration should be considered more advanced
	 * usage as it requires more understanding of how the framework is implemented.
	 *
	 * @param disableDefaults true if the default configuration should be disabled, else
	 * false
	 */
	protected WebSecurityConfigurerAdapter(boolean disableDefaults) {
		this.disableDefaults = disableDefaults;
	}

If you want to disable it just for testing purposes - Rather than completely disabling the auto-configuration, I create an "InsecurityConfiguration" in addition to "SecurityConfiguration", and activate it with either a Spring Profile or Property value.

Technically security is still configured, but wide open.

@Configuration
@ConditionalOnProperty(prefix = "security", value = "disabled", havingValue = "true")
public class InsecurityConfiguration extends WebSecurityConfigurerAdapter {
	
	private final static Logger log = LoggerFactory.getLogger(InsecurityConfiguration.class);

	@Override
	protected void configure(HttpSecurity http) throws Exception {
		log.warn("configuring insecure HttpSecurity");
		http.authorizeRequests().anyRequest().permitAll();
	}
	
	@Override
	public void configure(WebSecurity web) throws Exception {
		log.warn("configuring insecure WebSecurity");
		web.ignoring().antMatchers("/**");
	}
	
}

Note This is for mvc, not webflux. For Webflux you should create a SecurityWebFilterChain like Bryan mentioned.

This is how I generally disable basic auth in webflux, when using JWT -

    @Bean
    public SecurityWebFilterChain configure(ServerHttpSecurity http) {
    
	    http
	    .authorizeExchange().anyExchange().authenticated().and()
	        .httpBasic().disable()
	        .formLogin().disable()
	        .logout().disable()
	        .oauth2ResourceServer()
	        .jwt()
	        .and()
	        	.and().exceptionHandling().accessDeniedHandler(problemSupport);
	    return http.build();
    }

I have leveraged @ConditionalOnProperty to load the following SecurityConfig.java class if I set spring.security.enabled property to false in my application.yml to disable spring security and it works like a charm.

@ConditionalOnProperty(name = "spring.security.enabled", havingValue = "false")
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
            .authorizeRequests().antMatchers("/").permitAll();
    }
}

In Spring boot 2, there is no way to disable basic authentication by application.properties file. But the only thing is use annotation

@EnableAutoConfiguration(exclude = {SecurityAutoConfiguration.class})

in the main class. It works

The problem is with org.springframework.security.web.server.authorization.ExceptionTranslationWebFilter

it has private ServerAuthenticationEntryPoint authenticationEntryPoint = new HttpBasicServerAuthenticationEntryPoint();

so to fix it during ServerHttpSecurity initialization add:

http.exceptionHandling().authenticationEntryPoint(HttpStatusServerEntryPoint(HttpStatus.FORBIDDEN))

Looks like vanilla (servlet) spring uses org.springframework.security.config.annotation.web.configurers.ExceptionHandlingConfigurer#createDefaultEntryPoint

private AuthenticationEntryPoint createDefaultEntryPoint(H http) {
		if (this.defaultEntryPointMappings.isEmpty()) {
			return new Http403ForbiddenEntryPoint();
		}
		if (this.defaultEntryPointMappings.size() == 1) {
			return this.defaultEntryPointMappings.values().iterator().next();
		}
		DelegatingAuthenticationEntryPoint entryPoint = new DelegatingAuthenticationEntryPoint(
				this.defaultEntryPointMappings);
		entryPoint.setDefaultEntryPoint(this.defaultEntryPointMappings.values().iterator()
				.next());
		return entryPoint;
	}

Side note: mutable fields in builder style beans (like ExceptionTranslationWebFilter) make spring code hard to debug (too magic configuration as well)

To disable default security for Spring Boot Reactive Web applications, use the following excludes when you have actuator also in the classpath.

@SpringBootApplication(exclude = {ReactiveSecurityAutoConfiguration.class, ReactiveManagementWebSecurityAutoConfiguration.class })

You should add @EnableWebSecurity to enable a custom security configuration. After that simply disable the form login

@Configuration
@EnableWebSecurity
public class StackWebSecurityConfigurerAdapter extends 
WebSecurityConfigurerAdapter {
 @Override
 protected void configure(HttpSecurity http) throws Exception {
    http.formLogin().disable();
 }

}
