您需要允许对Spring Security配置中的Swagger资源进行未经身份验证的访问。以下方法对我有效：

@Configuration
@EnableWebSecurity
class WebSecurityConfiguration {

    private static final String[] SWAGGER_PATHS = {"/swagger-ui.html", "/v3/api-docs/**", "/swagger-ui/**", "/webjars/swagger-ui/**"};

    private final UserRegistrationFilter authenticationTokenFilter;

    @Bean
    SecurityFilterChain filterChain(final HttpSecurity http) throws Exception {
        return http
            // Configure access rules
            .authorizeHttpRequests(authorize -> authorize
                .antMatchers(SWAGGER_PATHS).permitAll()
                .anyRequest().authenticated())

            // All your other config

            .build();
    }

}
