spring mvc中未加载Swagger2配置类

Question

我正在为我的Spring REST项目建立swagger2文档。但是当我尝试执行http://localhost:8085/swagger-ui.html时，返回空页面。问题是我的bean类没有被我的spring MVC应用程序加载，它也不是Spring Boot应用程序。

下面是我的swagger2配置类

@Configuration
@EnableSwagger2
@EnableWebMvc
public class SwaggerConfig extends WebMvcConfigurerAdapter{

    @Bean
    public Docket newsApi() {
        System.out.println("!@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@22");
    return new Docket(DocumentationType.SWAGGER_2)
    .groupName("Dialr")
    .apiInfo(apiInfo())
    .select()
    .paths(regex("/*.*"))
    .build();
    }

    private ApiInfo apiInfo() {
    return new ApiInfoBuilder()
    .title("Spring REST Sample with Swagger")
    .description("Spring REST Sample with Swagger")
    .termsOfServiceUrl("http://www-03.ibm.com/software/sla/sladb.nsf/sla/bm?Open")
    .contact("Niklas Heidloff")
    .license("Apache License Version 2.0")
    .licenseUrl("https://github.com/IBM-Bluemix/news-aggregator/blob/master/LICENSE")
    .version("2.0")
    .build();
    }

}

请同时找到web.xml条目

</servlet>

<servlet-mapping>
    <servlet-name>rest</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>

如果有什么东西丢了，请告诉我？任何帮助都是非常感谢的。

由于servlet映射中的基本url映射是/rest/*，swagger-ui.html不会加载到http://localhost:8085/swagger-ui.html，所以尝试使用http://localhost:8085/rest/swagger-ui.html它可能会起作用
