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

问题描述 投票:2回答:6

我有自己的RequestMappingHandlerMapping,正在使用springfox-swagger-ui。添加我的自定义映射后,我无法在http://localhost:8080/swagger-ui.html处获得swagger ui。有什么想法吗?

这是我的配置。

    @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");
    }
}

这是我的pom.xml:

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

[当您覆盖WebMvcConfigurationSupport时,您还将覆盖Spring Boot的mvc自动配置(WebMvcAutoConfiguration)。因此,需要spring boot配置的资源将无法使用。这不是招摇不定的问题。

您可以在这里找到有关此的更多信息:

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

正如github问题所暗示的那样,将来会对此进行更改以使其更容易。当前有一些变通方法,如建议的那样。

一种快速而肮脏的方法是,将WebMvcAutoConfiguration类复制并粘贴到您自己的类中,从EnableWebMvcConfiguration的requestMappingHandlerMapping()方法返回您自己的HandlerMapping,并将WebMvcAutoConfiguration的副本注册为自动配置类。您可以在此处查看说明:

http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-developing-auto-configuration.html

请确保将WebMvcAutoConfiguration的副本放在没有组件自动扫描和拾取的某个程序包中。只需按照以上链接中的说明进行注册。

还请确保在从requestMappingHandlerMapping()方法返回自定义HandlerMapping的顺序之前将其设置为0,如下所示:

@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;
}

覆盖requestMappingHandlerMapping()WebMvcConfigurationSupport将关闭Spring Boot的自动配置。要添加自定义MVC组件,可以使用WebMvcRegistrations。就像提供自定义RequestMappingHandlerMapping一样,我们可以使用自定义getRequestMappingHandlerMapping()覆盖RequestMappingHandlerMappingWebMvcRegistrationsAdapter,并通过webMvcRegistrationsHandlerMapping()提供它。作为,

@Configuration
class CustomRequestMappingHandlerMapping {

    @Bean
    public WebMvcRegistrationsAdapter webMvcRegistrationsHandlerMapping() {
        return new WebMvcRegistrationsAdapter() {
            @Override
            public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
                return new ApiVersionRequestMappingHandlerMapping("v");
            }
        };
    }
}

它对我有用。覆盖addResourceHandlers而不是注册自动配置。

Github Source

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

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

在Spring Boot 2.0.0中,有一种更简单的方法可以实现此目的。

WebMvcRegistrations接口的实例创建为Bean,并覆盖适当的方法以返回该对象的自定义版本。 Spring Boot将读取并使用该实例。

在这种情况下,只需要覆盖getRequestMappingHandlerMapping()并返回自定义实现

可以通过使用WebMvcConfigurationSupport并为swagger添加资源处理程序来解决:

@Configuration
public class MvcConfiguration extends WebMvcConfigurationSupport {
    @Value("${spring.application.name}")
    private String applicationName;

    //...irrelevant code here

    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");

        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}

我终于找到了!正确的配置是这样的:

@Configuration
public class VersioningMappingHandlerConfig {

    @Bean
    public ApiVersionRequestMappingHandlerMapping customMappingHandlerMapping() {
        ApiVersionRequestMappingHandlerMapping handler = new ApiVersionRequestMappingHandlerMapping("v", 1, 1);
        handler.setOrder(-1);
        return handler;
    }

}

注意:没有extends WebMvcConfigurationSupport,bean名称是customMappingHandlerMapping
