springboot集成Swagger遇到的问题

springboot集成Swagger2以及解决遇到的问题

1. springboot集成Swagger-ui

   • swagger2 官网：https://swagger.io/

   • 在pom.xml添加依赖

     
             <dependency>
                 <groupId>io.springfoxgroupId>
                 <artifactId>springfox-swagger2artifactId>
                 <version>2.9.2version>
             dependency>
             <dependency>
                 <groupId>io.springfoxgroupId>
                 <artifactId>springfox-swagger-uiartifactId>
                 <version>2.9.2version>
             dependency>
             <dependency>
                 <groupId>com.google.guavagroupId>
                 <artifactId>guavaartifactId>
                 <version>25.1-jreversion>
             dependency>
     

   • swagger2配置类

     /**
     Swagger2配置类
     */
     
     @Configuration  //让Spring容器加载该配置类
     @EnableSwagger2 //用于启动swagger2
     public class SwaggerConfig {
     /**
     swagger2启动后，通过createRestApi函数常见Docker的Bean，
     apiInfo()用来创建该APi的基本信息（这些基本信息会展现在文档页面中）
     select（）函数返回一个ApiSelectorBuilder实例用来控制哪些接口暴露给Swagger来展现，
     这里使用指定扫描的包路径来定义，Swagger会扫描该包下所有Controller定义的API，并产生文档内容（除了被@ApiIgnore指定的请求）
     */
         @Bean
         public Docket createRestApi() {
             return new Docket(DocumentationType.SWAGGER_2)
                     .apiInfo(apiInfo())
                     .select()
                     .apis(RequestHandlerSelectors.basePackage("{扫描的使用swagger2的接口的包}"))
                     .paths(PathSelectors.any())
                     .build();
         }
     
         private ApiInfo apiInfo() {
             return new ApiInfoBuilder()
                     .title("Spring Boot中使用Swagger2构建RESTful APIs")
                     .description("摘要")
                     .termsOfServiceUrl("http://www.baidu.com/")
                     .contact("peter")
                     .version("1.0")
                     .build();
         }
     
      /*   @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/");
             super.addResourceHandlers(registry);
         }*/
     }
     

   • swagger2使用

      /**
          * 根据产品id和卖家id查询查询asin数据
          *
          * @return
          */
         @ApiOperation(value = "根据产品id查询asin数据", notes = "根据产品id查询asin数据")
         @ApiImplicitParam(name = "productId", value = "产品id")
         @RequestMapping(value = "/findAsinByProductId", method = RequestMethod.GET)
         public ResultBean findAsinByProductIdAndSellerId(@RequestParam("productId") Integer productId) {
             ResultBean resultBean = new ResultBean();
             try {
     
                 List<String> asins = productCodedInformationService.findAsinByProductId(productId);
                 resultBean.setData(asins);
             } catch (Exception e) {
                 resultBean.setCode(StatusCode.HTTP_FAILURE);
                 resultBean.setMsg("Request ProductCodedInformationHandler list Failed！");
                 LOGGER.error("查询asin列表失败！", e);
             }
             return resultBean;
         }
     

   • 成功后
     

2. 出现的问题
   访问swagger-ui.html不显示内容
   解决方式：

   //不显示内容的话需要配置静态资源路径
   /**
    * @ClassName UploadFilePathConfig
    * @Description TODO
    * @Author peter
    * @Date 19-4-15 下午5:41
    * @Version 1.0
    **/
   @Configuration
   public class UploadFilePathConfig extends WebMvcConfigurationSupport {
   	//这两个是我开放上传的路径
       @Value("${file.staticAccessPath}")
       private String staticAccessPath;
       @Value("${file.uploadFolder}")
       private String uploadFolder;
   
       @Override
       public void addResourceHandlers(ResourceHandlerRegistry registry) {
           registry.addResourceHandler(staticAccessPath)
                   .addResourceLocations("file:" + uploadFolder);
           //下面两个是配置swagger的静态资源访问路径
           registry.addResourceHandler("swagger-ui.html*")
                   .addResourceLocations("classpath:/META-INF/resources/");
           registry.addResourceHandler("/webjars/**")
                   .addResourceLocations("classpath:/META-INF/resources/webjars/");
           super.addResourceHandlers(registry);
       }
   }
