swagger-ui ->index.html 不存在 404 Spring Boot 3.1.5

Question

我正在尝试将 Springdoc open-api 定义集成到我的项目中。目前，由于某些奇怪的原因 /v3/api-docs 工作正常，它正在获取 API 的 JSON 版本，但 UI 不起作用，控制台正在打印未找到 index.html (404)。有没有办法让这个功能发挥作用？最新版本的 Springboot 有没有人遇到类似的问题？

这是我的安全配置：

@Configuration
@EnableWebSecurity
@RequiredArgsConstructor
public class SecurityConfiguration extends WebMvcConfigurationSupport {
    private final JwtAuthenticationFilter jwtAuthFilter;
    private final AuthenticationProvider authenticationProvider;

    private static final String[] URL_WHITELIST = {
            ApplicationConstants.AUTH + "/**",
            ApplicationConstants.PARKING_SPOT + ID,
            "/error",
            "/favicon.ico",
            "/swagger-resources",
            "/swagger-resources/**",
            "/configuration/ui",
            "/configuration/security",
            "/swagger-ui.html",
            "/webjars/**",
            "/v3/api-docs/**",
            "/api/public/**",
            "/api/public/authenticate",
            "/actuator/*",
            "/swagger-ui/**"
    };

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
                .csrf(AbstractHttpConfigurer::disable)
                .authorizeHttpRequests(authorize -> authorize
                        .requestMatchers(URL_WHITELIST)
                        .permitAll()
                        .anyRequest()
                        .authenticated())
                .sessionManagement(session -> session.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
                .authenticationProvider(authenticationProvider)
                .addFilterBefore(jwtAuthFilter, UsernamePasswordAuthenticationFilter.class);
        return http.build();
    }
}

以及OpenAPI初始化：

@Configuration
public class OpenApiConfiguration {
    @Bean
    public OpenAPI openAPI() {
        Info info = new Info()
                .title("ParkingTime API")
                .version("1.0");
        return new OpenAPI().info(info);
    }
}

Answer 1

由于您从

WebMvcConfigurationSupport

扩展，Spring Boot 将跳过

WebMvcAutoConfiguration

，这反过来又会导致 Swagger UI 自动配置也被跳过。

解决此问题的最简单方法是不要从

WebmvcConfigurationSupport

扩展。如果您确实需要提供额外的配置，您可以从

DelegatingWebMvcConfiguration

进行扩展，但在大多数情况下，您根本不需要扩展它。
