Swagger2 ui 无法访问 [英] Swagger2 ui not accessbile

问题描述

我在 Spring 启动应用程序中使用 Swagger，我以某种方式可以访问 Swagger 的大多数端点，例如 /v2/api-docs、/swagger-resources 但我不知道为什么 /swagger-ui.html 不可访问.

I am using Swagger in a Spring boot application, I somehow can access most of Swagger's endpoints such as /v2/api-docs, /swagger-resources but I can't figure out why /swagger-ui.html is not accessible.

我正在使用这些依赖项:

I am using these dependencies:

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

这是我的 Swagger 配置类:

here is my Swagger Config class:

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("app.controllers"))
                .paths(PathSelectors.any())
                .build();
    }
}

这是日志中有趣的部分:

Here is the interesting part of the log:

推荐答案

尝试添加这样的类

@Configuration
public class WebMvcConfiguration extends WebMvcConfigurationSupport {

  @Override
  public void addResourceHandlers(final ResourceHandlerRegistry registry) {
    // Make Swagger meta-data available via <baseURL>/v2/api-docs/
    registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    // Make Swagger UI available via <baseURL>/swagger-ui.html
    registry.addResourceHandler("/**").addResourceLocations("classpath:/META-INF/resources/");
  }
}
