authenticationManager 빈을 하나 생성하셔서 사용하시면 될 것 같습니다.<pre class="hljs"><code>@Bean
	AuthenticationManager authenticationManager(AuthenticationConfiguration authConfiguration) throws Exception {
		return authConfiguration.getAuthenticationManager();
	}</code></pre>&nbsp;<pre class="hljs"><code>@Bean
	public SecurityFilterChain configure(HttpSecurity http) throws Exception {
 AuthenticationManager authenticationManager = authenticationManager(http.getSharedObject(AuthenticationConfiguration.class)); 
 http.~~~
 .addFilter(getAuthenticationFilter(authenticationManager));
 return http.build();
}

private AuthenticationFilter getAuthenticationFilter(AuthenticationManager authenticationManager) {
		AuthenticationFilter authenticationFilter = new AuthenticationFilter(authenticationManager);
		return authenticationFilter;
	}</code></pre>&nbsp;또는<pre class="hljs"><code>@Bean
	public SecurityFilterChain configure(HttpSecurity http) throws Exception {
 
 http.~~~
 .addFilter(getAuthenticationFilter(http));
 return http.build();
}

private AuthenticationFilter getAuthenticationFilter(HttpSecurity http) {
		AuthenticationFilter authenticationFilter = new AuthenticationFilter(http.getSharedObject(AuthenticationConfiguration.class));
		return authenticationFilter;
	}</code></pre>이렇게 추가하시고AuthenticationFilter에서는<pre class="hljs"><code>@RequiredArgsConstructor
public class AuthenticationFilter extends UsernamePasswordAuthenticationFilter{

	private final AuthenticationManager authenticationManager;

 //attemptAuthentication

 //successAuthentication
}</code></pre>이렇게 적용해보시면 될 듯합니다.
