Spring boot&Swagger 2 UI和自定义requestmappinghandlermapping-映射问题

Question

    @Configuration
       public class WebMvcConfig extends WebMvcConfigurationSupport {
    @Override
    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        return new ApiVersionRequestMappingHandlerMapping("v");
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry
          .addResourceHandler("/webjars/**")
          .addResourceLocations("(META-INF/resources/webjars");
    }
}

下面是我的pom.xml：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.hateoas</groupId>
        <artifactId>spring-hateoas</artifactId>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.4.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.4.0</version>
    </dependency>
    <dependency>
        <groupId>javax.inject</groupId>
        <artifactId>javax.inject</artifactId>
        <version>1</version>
    </dependency>

当您重写WebMvcConfigurationSupport时，您也重写了spring Boot的mvc自动配置（WebMvcAutoConfiguration）。因此，需要spring Boot的配置的资源将无法工作。这不是Swagger特有的问题。

您可以在此找到更多信息：

https://github.com/spring-projects/spring-boot/issues/5004

@Bean
@Primary
@Override
public RequestMappingHandlerMapping requestMappingHandlerMapping() {
    // Must be @Primary for MvcUriComponentsBuilder to work

    ApiVersionRequestMappingHandlerMapping handlerMapping = new ApiVersionRequestMappingHandlerMapping("v");
    handlerMapping.setOrder(0);
    handlerMapping.setInterceptors(getInterceptors());
    handlerMapping.setContentNegotiationManager(mvcContentNegotiationManager());

    PathMatchConfigurer configurer = getPathMatchConfigurer();
    if (configurer.isUseSuffixPatternMatch() != null) {
        handlerMapping.setUseSuffixPatternMatch(configurer.isUseSuffixPatternMatch());
    }
    if (configurer.isUseRegisteredSuffixPatternMatch() != null) {
        handlerMapping.setUseRegisteredSuffixPatternMatch(configurer.isUseRegisteredSuffixPatternMatch());
    }
    if (configurer.isUseTrailingSlashMatch() != null) {
        handlerMapping.setUseTrailingSlashMatch(configurer.isUseTrailingSlashMatch());
    }
    if (configurer.getPathMatcher() != null) {
        handlerMapping.setPathMatcher(configurer.getPathMatcher());
    }
    if (configurer.getUrlPathHelper() != null) {
        handlerMapping.setUrlPathHelper(configurer.getUrlPathHelper());
    }

    return handlerMapping;
}
