Spring Security Java Config

Question

I'm trying to use JavaConfig instead of XML configuration for Spring Security. I would like to use @PreAuthorization for declaring access rights.

My Spring Security Config looks like this:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity( prePostEnabled = true )
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void registerAuthentication( AuthenticationManagerBuilder auth ) throws Exception {
        auth
            .inMemoryAuthentication()
            .withUser( "user" ).password( "password" ).roles( "USER" );
    }
}

However, this doesn't work. Once I deploy my web application I receive an error Error creating bean with name 'methodSecurityInterceptor' defined in class path resource.

After some research I found out that I have to add the aopalliance library to my project. Unfortunately that didn't resolved my problem.

Here is the complete stack trace:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'methodSecurityInterceptor' defined in class path resource [org/springframework/security/config/annotation/method/configuration/GlobalMethodSecurityConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.aopalliance.intercept.MethodInterceptor org.springframework.security.config.annotation.method.configuration.GlobalMethodSecurityConfiguration.methodSecurityInterceptor() throws java.lang.Exception] threw exception; nested exception is java.lang.IllegalArgumentException: Expecting to only find a single bean for type interface org.springframework.security.authentication.AuthenticationManager, but found []

Answer 1

According to your stacktrace, there’s no AuthenticationManager bean in your context.

Expecting to only find a single bean for type interface org.springframework.security.authentication.AuthenticationManager, but found []

It seems that you need to explicitly expose AuthenticationManager as a bean; try this:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void registerAuthentication(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
            .withUser( "user" ).password( "password" ).roles( "USER" );
    }

    @Bean @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

Answer 2

As NimChimpsky notes, Spring 3.2.0.RELEASE requires a configuration update.

Using this configuration, I was getting exactly the same exception as the OP, but only about half the time. The other half of the time the app started up just fine. I assume that there's some kind of race condition.

Originally I was pulling the security configuration in using @Import on my root configuration:

@Configuration
@Import(SecurityConfig.class)
... other annotations ...
public class RootConfig {
   ...
}

When I replaced that with

public class WebAppInit extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { RootConfig.class, SecurityConfig.class };
    }
}

the problem went away. Didn't dive into the reasons why, so I can't speak to that, but you might give it a try.

Answer 3

from the stacktrace, you don't have authentication manager defiend correctly :

Caused by: java.lang.IllegalArgumentException: Expecting to only find a single bean for type interface org.springframework.security.authentication.AuthenticationManager, but found []

Here is working example :

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("user").password("password").roles("USER");
    }
}

Just add the global method annotation, and change to method to not override and be autowired.

Answer 4

In my case, I have a line super.configure(auth); in the overriding method configure(AuthenticationManagerBuilder auth).

After it was removed, the exception is gone.
