While accessing swagger API, I get java.lang.NoSuchMethodError: 'void org.springframework.web.method.ControllerAdviceBean.(java.lang.Object)':

I'm using Spring Boot 3.4.5 with springdoc-openapi-starter-webmvc-ui:2.3.0 to integrate Swagger UI in my Spring Boot REST application. I have shown the security configuration in the below:

@Bean
    SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http.cors(Customizer.withDefaults()).csrf(AbstractHttpConfigurer::disable)
                .exceptionHandling((exceptionHandling) -> exceptionHandling.authenticationEntryPoint(authenticationEntryPoint))
                .sessionManagement((sm) -> sm.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
                .authorizeHttpRequests(
                        (authRequest) ->
                                authRequest.requestMatchers("/").permitAll()
                                        .requestMatchers("/api-docs",
                                                "/configuration/ui",
                                                "/api-docs/**",

                                                "/configuration/security",
                                                "/swagger-ui/**",

                                        .requestMatchers("/account/login").permitAll()
                                        .requestMatchers("/account/verify").permitAll()
                                        .requestMatchers(HttpMethod.GET, "/imgs/**").permitAll()
                                        .requestMatchers("/account/forget-password").permitAll()
                                        .requestMatchers("/account/forget-password/verify").permitAll()
                                        .requestMatchers("/account/reset-password").permitAll()
                                        .anyRequest().authenticated())
                .authenticationProvider(authenticationProvider());
        http.addFilterBefore(authenticationFilter, UsernamePasswordAuthenticationFilter.class);
        return http.build();
    }

I got the following error in my console

Is this because @ControllerAdvice is only used here in the code?

Seems like your issue is not caused by @ControllerAdvice or your custom exception handling.
I guess the actual root cause seems to be a version incompatibility between springdoc-openapi-starter-webmvc-ui:2.30 and Spring Boot 3.4.5

Tr to upgrade springdoc-openapi to a compatible version from 2.3.0 to 2.3.1 or later. Its compatible with `Spring Boot 3.2+, so it will work with 3.4.5

For more detailed explanantion, please check the stackoverflow.

Hi @roberta484

The error you got typically means there is a binary incompatibility between Spring Framework version you are using and the version that springdoc-openapi was compiled against.

So I suggest to downgrade the Spring Boot to 3.18

Thanks

I also think this is because of version compatibility

Seems like your issue is not caused by @ControllerAdvice or your custom exception handling.
I guess the actual root cause seems to be a version incompatibility between springdoc-openapi-starter-webmvc-ui:2.30 and Spring Boot 3.4.5

Tr to upgrade springdoc-openapi to a compatible version from 2.3.0 to 2.3.1 or later. Its compatible with `Spring Boot 3.2+, so it will work with 3.4.5

For more detailed explanantion, please check the stackoverflow.
