Swagger HK2 服务修正失败

问题描述 投票：0回答：3

此应用程序使用 Swagger（swagger-jersey2-jaxrs，1.5.18）、Spring-boot（spring-boot-starter-jersey，2.0.1.RELEASE）和 Java 9。当应用程序运行 Swagger UI 加载时没有问题。但我可以在日志中看到以下警告。感谢任何解决这个问题的想法。我尝试过升级版本但无济于事。

请在 pom.xml 文件中插入 jersey-hk2 的 2.26。我尝试过，它对我有用

升级到 spring-boot-starter-jersey 至版本 2.0.3.RELEASE。然后这个警告就消失了。

此警告是由 swagger-jersey-jaxrs2 1.5.X 期望 ApiListingResource 中的 ServletConfig 对象引起的。

修复：

  1. 创建以下类：
// Alternate implementation of swagger-jersey-jaxrs2's ApiListingResource class. 
// Needed to support running jersey as a servlet filter without any warnings from the jersey class analyzer.
@Path("/swagger.{type:json|yaml}")
public class FilterApiListingResource extends BaseApiListingResource {

    @Inject ServletConfig servletConfig;
    
    @Context ServletContext context;

    @GET
    @Produces({MediaType.APPLICATION_JSON, "application/yaml"})
    @ApiOperation(value = "The swagger definition in either JSON or YAML", hidden = true)
    public Response getListing(
            @Context Application app,
            @Context HttpHeaders headers,
            @Context UriInfo uriInfo,
            @PathParam("type") String type) {
        return getListingJsonResponse(app, context, servletConfig, headers, uriInfo);
    }
}
  1. 不要在 jersey ResourceConfig 中注册 ApiListingResource，而是注册 FilterApiListingResource

更深入的解释： 这个问题与 swagger-jersey-jaxrs2、jersey 和 Spring boot 之间的交互有关。

根据我的理解，这是发生的事情：

  1. Jersey 调用 hk2 来提供 ServletConfig 对象。
  2. Spring boots jersey 集成有一个 hk2 桥，因此 Spring Boot ioc 提供回 FilterConfig 对象。
  3. JerseyClassAnalyzer 尝试将提供的 FilterConfig 对象具体化为 ServletConfig，但 FilterConfig 未实现 ServletConfig，因此 JerseyClassAnalyzer 会抛出警告，然后将 FilterConfig 注入 swagger-jersey-jaxrs2 中。
  4. swagger-jersey-jaxrs2 将 FilterConfig 传递给 swagger 核心（swagger-jersey-jaxrs2 的传递依赖），由于 swagger 核心支持将球衣作为过滤器运行，因此它无论如何都可以工作。

我相信 swagger-jersey-jaxrs2 可以通过重构依赖于 Jerseys WebConfig 接口而不是 ServletConfig 来修复此警告。 Webconfig 是 jersey 抽象引用实现 ServletConfig 或 FilterConfig 的对象的方式。

这是可行的，因为 FilterApiListingResource 跳过了 JerseyClassAnalyzer 的具体化过程，并使用 Spring ioc 将 FilterConfig 作为 ServletConfig 注入。
