How To Inject AuthenticationManager using Java Configuration in a Custom Filter

Question

I m using Spring Security 3 2 and Spring 4 0 1  I m working on converting an xml config into a Java config  When I annotate AuthenticationManager with  Autowired in my Filter  I m getting an exception   Caused by  org springframework beans factory NoSuchBeanDefinitionException  No qualifying bean of type  org springframework security authentication AuthenticationManager  found for dependency  expected at least 1 bean which qualifies as autowire candidate for this dependency  Dependency annotations       I ve tried injecting AuthenticationManagerFactoryBean but that also fails with a similar exception   Here is the XML configuration I m working from   lt  xml version  1 0  encoding  UTF-8   gt   lt beans     gt       lt security authentication-manager id  authenticationManager  gt

Override method authenticationManagerBean in WebSecurityConfigurerAdapter to expose the AuthenticationManager built using configure AuthenticationManagerBuilder  as a Spring bean   For example       Bean name   BeanIds AUTHENTICATION MANAGER      Override    public AuthenticationManager authenticationManagerBean   throws Exception          return super authenticationManagerBean

In addition to what Angular University said above you may want to use  Import to aggregate  Configuration classes to the other class  AuthenticationController in my case       Import SecurityConfig class   RestController public class AuthenticationController    Autowired private AuthenticationManager authenticationManager    some logic     Spring doc about Aggregating  Configuration classes with  Import  link
