Question

我试图按照他们提供的指南将Swagger整合到我的Jersey应用程序中：https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-Jersey-1.X-Project-Setup-1.5

我使用的是Jersy v1.17而我使用的是自定义应用而不是web.xml

以下是我在简单测试项目中失败的所有内容！

public class ResConfig extends DefaultResourceConfig { // custom app
    public ResConfig() {
        super();
        BeanConfig beanConfig = new BeanConfig();
        beanConfig.setVersion("1.0.2");
        beanConfig.setSchemes(new String[] { "http" });
        beanConfig.setHost("localhost:9998");
        beanConfig.setBasePath("/api");
        beanConfig.setResourcePackage("test.resources"); // the package containing my resource
        beanConfig.setScan(true);
    }
}

我拥有的简单资源

@Path("hello")
@Produces("application/json")
public class Res {
    public Res() {
    }


    @GET
    public Response getHello() {
        Result result = new Result(); // Result is annotated with XmlRootElement and contains one field String str;
        result.setStr("hello");
        return Response.status(Status.OK).entity(result).build();
    }
}

主要：

 public static void main(String[] args) throws Exception {
    ResConfig resConfig = new ResConfig();

    resConfig.getClasses().add(Res.class);
    resConfig.getClasses().add(io.swagger.jaxrs.listing.ApiListingResource.class);
    resConfig.getClasses().add(io.swagger.jaxrs.listing.SwaggerSerializers.class);

    GrizzlyServerFactory.createHttpServer("http://localhost:9998/", resConfig);

    System.in.read();
}

POM包含以下内容：

我在Google的前两页搜索了答案，但没有任何帮助！

Swagger使用Servlet API，因此应用程序必须在servlet环境中运行。您配置Grizzly的方式不设置servlet容器。它只是一个HTTP服务器。

您希望使用jersey-grizzly2-servlet依赖项，并使用GrizzlyWebContainerFactory来引导应用程序。这将设置一个servlet容器。

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-grizzly2-servlet</artifactId>
    <version>1.19.1</version>
</dependency>

Map<String, String> initParams = new HashMap<>();
initParams.put("javax.ws.rs.Application", "com.package.ResConfig");
GrizzlyWebContainerFactory.create(uri, initParams);

Swagger ApiListingResource无法识别为有效资源
