swagger3使用异常

使用springboot+springsecurity+swagger3,访问swagger地址出现异常，具体如下

我有给对应的路径放行

          private static final String[] URL={
            "/favicon.ico",
            "/swagger-ui/**",
            "/swagger-resources/**",
            "/v2/api-docs",
            "/v3/api-docs",
            "/webjars/**",
    };
.............................
.antMatchers(URL).permitAll()

奇怪的是/v2/api-docs能出来数据，但是/v3/api-docs不能出来数据，为什么

swagger配置类如下

@Configuration
@EnableOpenApi
public class Swagger3 {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                .paths(PathSelectors.any())
                .build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Spring Boot Swagger3接口文档")
                .description("测测测测")
                .contact(new Contact("rgh","https://localhost","1111@qq.com"))
                .termsOfServiceUrl("https://localhost")
                .version("1.0")
                .build();
    }
}
