正如大家所知，WebSecurityConfigurerAdapter类已被废弃。
我尝试在我的filterChain中实现customFilter，但是我遇到了一个与新的AuthenticationManager相关的问题。
问题就在这里：

@Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http.cors().and().csrf().disable();
        http.sessionManagement().sessionCreationPolicy(STATELESS);
        http.authorizeRequests().anyRequest().permitAll();
        http.addFilter(new CustomAuthenticationFilter(authenticationManager()));
        return http.build();
    }

    @Bean
    public AuthenticationManager authenticationManager(AuthenticationConfiguration authenticationConfiguration) throws Exception {
        return authenticationConfiguration.getAuthenticationManager();
    }

如您所见，Authentication Manager需要AuthenticationConfiguration类作为NotNull参数，如果没有它，我将无法创建CustomAuthenticationFilter。
有人遇到过这个问题吗？我需要为AuthenticationConfiguration创建一个新的@Bean吗？
下面是我的CustomAuthenticationFilter类：

@Slf4j
public class CustomAuthenticationFilter extends UsernamePasswordAuthenticationFilter {

    private final AuthenticationManager authenticationManager;

    public CustomAuthenticationFilter(AuthenticationManager authenticationManager) {
        this.authenticationManager = authenticationManager;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        String username  = request.getParameter("username");
        String password = request.getParameter("password");
        log.info("Userame is {}", username);
        log.info("passoword is {}", password);
        UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(username, password);
        return authenticationManager.authenticate(authenticationToken);
    }

    @Override
    protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult) throws IOException, ServletException {
        super.successfulAuthentication(request, response, chain, authResult);
    }
}
