SpringBoot configures SwaggerUI to access the 404 pit.

When I was learning SpringBoot to build Restful API, I encountered a small pit, which was inaccessible when configuring Swagger UI.

First add the Swagger dependency to your pom file, as shown below:

<dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger-ui</artifactId>
      <version>2.2.2</version>
    </dependency>

    <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger2</artifactId>
      <version>2.2.2</version>
</dependency>

Copy after login

Then create a new SwaggerConfig class:

Configuration
@EnableSwagger2
public class SwaggerConfig {
  @Bean
  public Docket createRestApi() {
    return new Docket(DocumentationType.SWAGGER_2)
        .apiInfo(apiInfo())
        .select()
        .apis(RequestHandlerSelectors.basePackage("com.nightowl"))
        .paths(PathSelectors.any())
        .build();
  }
  private ApiInfo apiInfo() {
    return new ApiInfoBuilder()
        .title("NightOwl RESTful APIs")
        .description("关注我 http://hwangfantasy.github.io/")
        .termsOfServiceUrl("http://hwangfantasy.github.io/")
        .contact("颜艺学长")
        .version("1.0")
        .build();
  }
}

Copy after login

Finally add it to your Controller The previous series of API annotations are enough. In fact, it can be used normally without adding API annotations.
Finally, visit localhost:8080/swagger-ui.html to see the swagger page.

But here comes the key. The first time I configured it in this way, I got the following error:

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available

Copy after login

But I created a new project and reconfigured it without any problems, so I thought of it in my own project. There must be some configuration that conflicts with swagger.
Finally found that commenting out the

spring.resources.static-locations=classpath:/static/

Copy after login

line in application.properties can be accessed.
