Cannot pass AuthenticationManager to custom filter by @Autowired

Question

I\'m trying pass filter JWTLoginFilter to WebSecurityConfig WebSecurityConfigurerAdapter by @Autowired annotation. The problem arise when JWTLoginFilter try get AuthenticationMa

Answer 1

Your WebSecurityConfig explicitly requests JWTLoginFilter to be injected in it, and JWTLoginFilter requests AuthenticationManager to be injected in its constructor. AuthenticationManager is supplied by WebSecurityConfig, so you have a circular dependency.

Remove @Component annotation from JWTLoginFilter and define the filter as a bean in WebSecurityConfig:

@Bean
public JWTLoginFilter jwtLoginFilter() {
    return new JWTLoginFilter("/login", authenticationManager());
}

You will probably also need to inject UserService manually in this method (for example, via constructor).
