I have a security jar that I am implementing in my project. I am extending the BasicSecurityConfig which extends WebSecurityConfigurerAdapter and has all the filters. I was told that all I need is to extend the BasicSecurityConfig and call super().configure which will call the parent’s configure method. However, I am getting this error,

Field authenticationManager in com.custom.security.CustomSecurityFilter required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found. 

The parent class already has an AuthenticationManager bean, I shouldn’t need to define it in the child class too.

My Security Class

    public class SecurityConfiguration extends BasicSecurityConfig {      private static final String PAYMONEYROLE = "(hasRole('EE'))";      @Override     protected void configure(HttpSecurity http) throws Exception {         // must call super first         super.configure(http);         http.authorizeRequests()                 .antMatchers(HttpMethod.POST, "/v1/cart/validate").authenticated()                 .antMatchers(HttpMethod.POST, "/v1/cart/validate").access(PAYMONEYROLE)                 .and().cors().and().csrf().disable();     }     @Bean     public FilterRegistrationBean invalidResourceFilterRegistration(InvalidResourceFilter invalidResourceFilter) {         FilterRegistrationBean registration = new FilterRegistrationBean(invalidResourceFilter);         registration.setEnabled(false);         invalidResourceFilter.setDisabled(true);         return registration;     }      @Bean     public FilterRegistrationBean customSecurityFilterRegistration(CustomSecurityFilter customSecurityFilter) {         FilterRegistrationBean registration = new FilterRegistrationBean(customSecurityFilter);         registration.setEnabled(false);          return registration;     }     } 

Custom Security Jar

    public class BasicSecurityConfig extends WebSecurityConfigurerAdapter {     @Autowired     private ApplicationContext applicationContext;     @Autowired     private InvalidResourceFilter invalidResourceFilter;      public BasicSecurityConfig() {     }      protected void configure(HttpSecurity http) throws Exception {         ((HttpSecurity)((HttpSecurity)http.addFilterBefore(this.customSecurityFilter(), AbstractPreAuthenticatedProcessingFilter.class).addFilterAfter(this.invalidResourceFilter, FilterSecurityInterceptor.class).sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()).exceptionHandling().authenticationEntryPoint(this.authenticationEntryPoint()).accessDeniedHandler(this.customDeniedHandler()).and()).authorizeRequests().accessDecisionManager(this.accessDecisionManager());     }      public void configure(WebSecurity web) throws Exception {         web.ignoring().antMatchers(new String[]{"/docs**/**", "/swagger-ui.html**/**", "/webjars**/**", "/swagger-resources**/**", "/api-docs**/**", "/v2/api-docs**", "/version.json**"});     }      @Autowired     public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {         auth.authenticationProvider(this.customAuthenticationProvider());     }      @Bean     public AuthenticationManager authenticationManagerBean() throws Exception {         return super.authenticationManagerBean();     }      @Bean     public DefaultWebSecurityExpressionHandler defaultWebSecurityExpressionHandler() {         return new CustomWebSecurityExpressionHandler();     }      @Bean     public CustomSecurityFilter customSecurityFilter() {         return new CustomSecurityFilter();     }      @Bean     public AuthenticationProvider customAuthenticationProvider() {         return new CustomAuthenticationProvider();     }      @Bean     public AuthenticationSuccessHandler customSuccessHandler() {         return new CustomSuccessHandler();     }      @Bean     public AccessDeniedHandler customDeniedHandler() {         return new CustomAccessDeniedHandler();     }      @Bean     public AuthenticationEntryPoint authenticationEntryPoint() {         return new CustomAuthenticationEntryPoint();     }      @Bean     public CustomSystemUserAuthVoter customSystemUserAuthVoter() {         return new CustomSystemUserAuthVoter();     }      @Bean     public WebExpressionVoter webExpressionVoter() {         WebExpressionVoter wev = new WebExpressionVoter();         wev.setExpressionHandler(this.defaultWebSecurityExpressionHandler());         return wev;     }      @Bean     public AccessDecisionManager accessDecisionManager() {         return new ExplicitDecisionManager(Arrays.asList(this.customSystemUserAuthVoter(), this.webExpressionVoter()));     } }
