Getting HTTP 404 error on /swagger-ui.html but other swagger endpoint works

Getting HTTP 404 error on http://localhost:8080/myapp/swagger-ui.html, while integrating swagger-ui in RESTful API app (spring-boot app).

Other swagger endpoints are working as expected (/swagger-resources/configuration/ui, /swagger-resources/configuration/security, /v2/api-docs). I can see the JSON response.

• Versions Info
  • spring-boot 1.3.5 (spring-boot-starter-tomcat).
  • Swagger 2.5.0 for both springfox-swagger2 & springfox-swagger-ui
• This is a spring-boot app and serves RESTful api’s and does not have any static content. Hence no webapp, web, META-INF/resources etc folders in source code.
• pom.xml

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.5.0</version>
        </dependency>

• I am not using @EnableWebMvc anywhere in code
• SwaggerConfiguration.java

@Configuration
@EnableSwagger2
@Profile("dev")
public class SwaggerConfiguration implements EnvironmentAware {
  @Bean
  public Docket swaggerSpringfoxDocket() {
    Docket docket = new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo())
            .genericModelSubstitutes(ResponseEntity.class).forCodeGeneration(true)
            .genericModelSubstitutes(ResponseEntity.class)
            .directModelSubstitute(LocalDate.class, String.class)
            .directModelSubstitute(LocalDateTime.class, Date.class)
            .directModelSubstitute(ZonedDateTime.class, Date.class).select()
            .paths(regex("/api/.*")).build();
    return docket;
  }
  private ApiInfo apiInfo() {
    return new ApiInfo(propertyResolver.getProperty("title"),
            propertyResolver.getProperty("description"),
            propertyResolver.getProperty("version"),
            propertyResolver.getProperty("termsOfServiceUrl"),
            new Contact(propertyResolver.getProperty("contact.name"),
                    propertyResolver.getProperty("contact.url"),
                    propertyResolver.getProperty("contact.email")),
            propertyResolver.getProperty("license"),
            propertyResolver.getProperty("licenseUrl"));
  }

• Not sure if this will impact, but i do have below for configuring Metrics

@Configuration
public class WebConfigurer implements ServletContextInitializer, EmbeddedServletContainerCustomizer {
  @Autowired(required = false)
  private MetricRegistry metricRegistry;

I also received 404 on getting HTML UI docs. I am having spring boot webflux project and the resolution was fairly simple: current 3.0.0-SNAPSHOT version changed the UI URL to /swagger-ui/ instead of the old /swagger-ui.html

Remove all you explicit tweaks and hacks and just depend on the new springfox-boot-starter as written here.

I realize this is closed, but for people with similar problems the issue I had was we had a class extending the WebMvcConfigurationSupport and overriding methods, but we should have been using WebMvcConfigurerAdapter and overriding methods there. That fixed our issues.
