当我在“filter chain”方法中使用AuthentiationManager对象时，代码工作正常，但我不知道为什么。是否由于某种原因，认证管理器bean被创建了两次？如果是，如何解决？
这是我的SecurityConfig类：

@EnableWebSecurity(debug = true)
@ComponentScan(basePackages = "com.Jahedullah")
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig{
    private final PasswordEncoder passwordEncoder;
    private final ApplicationUserService applicationUserService;

    public SecurityConfig(ApplicationUserService applicationUserService, PasswordEncoder passwordEncoder) {
        this.applicationUserService = applicationUserService;
        this.passwordEncoder = passwordEncoder;
    }

    public AuthenticationManager authenticationManager(HttpSecurity http) throws Exception {
        AuthenticationManagerBuilder authenticationManagerBuilder =
                http.getSharedObject(AuthenticationManagerBuilder.class);
        authenticationManagerBuilder.authenticationProvider(daoAuthenticationProvider());
        return authenticationManagerBuilder.build();
    }

    // This Bean is Used when you are using CustomUserDetailsService -> which is used to fetch user Id and Pass and other info from DB.
    @Bean
    public DaoAuthenticationProvider daoAuthenticationProvider(){
        DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
        provider.setPasswordEncoder(passwordEncoder);
        provider.setUserDetailsService(applicationUserService);

        return  provider;
    }
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
            .addFilter(new JwtUsernameAndPasswordAuthenticationFilter(authenticationManager(http)))
            .authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers(HttpMethod.DELETE,"/Products/**").hasAuthority(PRODUCT_WRITE.getPermission())
                .antMatchers(HttpMethod.PUT,"/Products/**").hasAuthority(PRODUCT_WRITE.getPermission())
                .antMatchers(HttpMethod.POST,"/Products/**").hasAuthority(PRODUCT_WRITE.getPermission())
                .antMatchers(HttpMethod.GET,"/Products/**").hasAnyRole(ADMIN.name(), USER.name())
                .anyRequest().authenticated();

        http
            .csrf().disable();

        return http.build();
    }
}

下面给出了显示给我的错误。有人能解释一下引擎盖下面发生了什么吗？这两个bean被示例化的确切位置在哪里？
