以编程方式将servlet添加到嵌入的grizzly

Question

我正在尝试将Swagger集成到运行嵌入式grizzly服务器的Java SE应用程序中。

为了达到这个目的，我跟在tutorial之后，我确信我在那里90％。

我想用这个servlet来配置招摇：

@WebServlet(name = "SwaggerJaxrsConfig", loadOnStartup = 1) 
public class SwaggerJaxrsConfig extends HttpServlet { 

    @Override 
    public void init(ServletConfig servletConfig) { 
     try { 
      super.init(servletConfig); 
      System.out.println("Swagger init"); 
      SwaggerConfig swaggerConfig = new SwaggerConfig(); 
      ConfigFactory.setConfig(swaggerConfig); 
      swaggerConfig.setBasePath("http://localhost:8082/swagger4javaee-web/rest"); 
      swaggerConfig.setApiVersion("1.0.0"); 
      ScannerFactory.setScanner(new DefaultJaxrsScanner()); 
      ClassReaders.setReader(new DefaultJaxrsApiReader()); 
     } catch (ServletException e) { 
      System.out.println(e.getMessage()); 
     } 
    } 
} 

因为我'使用嵌入式服务器，@WebServlet标注不加servlet来灰熊服务器。

有没有人知道我可以如何将servlet以编程方式添加到灰熊服务器？

PS我'使用这种依赖

<dependency> 
    <groupId>org.glassfish.jersey.containers</groupId> 
    <artifactId>jersey-container-grizzly2-servlet</artifactId> 
    <version>2.9</version>

我下面的作品。我希望它也适用于你。

public class Main { 

    private static final URI BASE_URI 
      = URI.create("http://localhost:8080/api/"); 

    public static void main(String[] args) { 
     try { 
      BeanConfig beanConfig = new BeanConfig(); 
      beanConfig.setVersion("1.0"); 
      beanConfig.setScan(true); 
      beanConfig.setResourcePackage(

      beanConfig.setBasePath(BASE_URI.toString()); 
      beanConfig.setDescription("Hello resources"); 
      beanConfig.setTitle("Hello API"); 

      final HttpServer server 
        = GrizzlyHttpServerFactory.createHttpServer(
          BASE_URI, createApp()); 

      System.out.println(
        String.format(
          "Application started.%nHit enter to stop it...")); 
      System.in.read(); 
      server.shutdownNow(); 
      System.exit(0); 
     } catch (IOException ex) { 
      Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex); 
     } 
    } 

    public static ResourceConfig createApp() { 
     return new ResourceConfig(). 
       packages(HelloResource.class.getPackage().getName(), 
         "com.wordnik.swagger.jaxrs.listing"). 
       register(createMoxyJsonResolver()); 
    } 

    public static ContextResolver<MoxyJsonConfig> createMoxyJsonResolver() { 
     final MoxyJsonConfig moxyJsonConfig = new MoxyJsonConfig(); 
     Map<String, String> namespacePrefixMapper 
       = new HashMap<String, String>(1); 
     namespacePrefixMapper.put(

     moxyJsonConfig.setNamespacePrefixMapper(namespacePrefixMapper) 
       .setNamespaceSeparator(':'); 
     return moxyJsonConfig.resolver(); 
    } 

} 

HelloResource.java

import com.wordnik.swagger.annotations.Api;

@Path("hello") 
@Api(value = "/hello", description = "Say Hello!") 
public class HelloResource { 

    @GET 
    @Produces(MediaType.APPLICATION_JSON) 
    @ApiOperation(value = "Say Hello World", 
      notes = "Anything Else?") 
    @ApiResponses(value = { 
     @ApiResponse(code = 200, message = "OK"), 
     @ApiResponse(code = 500, message = "Something wrong in Server")}) 
    public Response sayHello() { 
     JsonObject value = Json.createObjectBuilder() 
       .add("firstName", "Jeremy") 
       .add("lastName", "Chung") 
       .add("message", "Hello World!") 
       .build(); 
     return Response.status(200).entity(value).build(); 
    } 
} 

的Maven 的pom.xml包含以下依赖性。

调用http://localhost:8080/api/hello结果：

{ “名字”： “杰里米”， “姓氏”： “钟”， “消息”： “Hello World” 的}

调用http://localhost:8080/api/api-docs结果：

{ “apiVersion”： “1.0”， “swaggerVersion”： “1.2”， “的API”：[{ “路径”： “/你好”，“DESCRIPTIO N “：” 说 你好“}]}

调用http://localhost:8080/api/api-docs/hello结果：

{"apiVersion":"1.0","swaggerVersion":"1.2","basePath":"http://localhost:8080/api/","resourcePath":"/hello","apis":[{"path":"/hello","operations":[{"method":"GET","summary":"Say Hello World","notes":"Anything Else?","type":"void","nickname":"sayHello","produces":["application/json"],"parameters":[],"responseMessages":[{"code":200,"message":"OK"},{"code":500,"message":"Something wrong in Server"}]}]}]}
