使用Swagger和Jaxrs为项目添加Swagger servlet支持

我有一个使用Jaxrs Swagger的嵌入式Jetty应用程序（用Java），工作得很好（最后） . 它在简单的JSON对象上实现基本的REST操作（GET，PUT，POST，DELETE） .

我有几个HTTPServlet处理我的一些REST API，并希望添加Swagger支持 . 我能找到的设置Swagger Servlet的唯一例子是使用web.xml进行配置 .

不幸的是，我的应用程序不使用web.xml，它用Java配置所有内容 .

1）Swagger是否可以同时支持Jaxrs和Servlets？ （他们互相排斥吗？）
2）如果可能，我如何配置Swagger以支持Java中的Servlet？

这是我带注释的API：

@Api(value = "myService",
        description = "My Config Service API",
        produces = "application/json",
        consumes = "application/json")
@Path("/env")
@Produces("application/json")
@Consumes("application/json")
public class MyServiceResource
{
    @GET
    @Path("/thing/{thingName}")
    @ApiOperation(value = "Gets Thing", response = Thing.class)
    public Response getThing(
            @PathParam("thingName") String thingName) throws IOException
    {
        return blah blah blah
    }

    blah blah blah
}

这是Swagger配置文件：

@WebServlet(name = "SwaggerJaxrsConfig", loadOnStartup = 1)
public class SwaggerJaxrsConfig extends HttpServlet {
    @Override
    public void init(ServletConfig servletConfig) {
        super.init(servletConfig);
        SwaggerConfig swaggerConfig = new SwaggerConfig();
        ConfigFactory.setConfig(swaggerConfig);
        swaggerConfig.setBasePath("http://localhost:8002");
        swaggerConfig.setApiVersion("1.0.0");
        ScannerFactory.setScanner(new DefaultJaxrsScanner());
        ClassReaders.setReader(new DefaultJaxrsApiReader());
    }
}

这里有一些文件可以做更多的Swagger设置：

public class ServiceApplication extends Application
{
    HashSet<Object> singletons = new HashSet<Object>();

    public ServiceApplication()
    {
        singletons.add(new MyServiceResource());
    }

    @Override
    public Set<Class<?>> getClasses()
    {
        Set<Class<?>> resources = new java.util.HashSet<Class<?>>();
        resources.add(ApiDeclarationProvider.class);
        resources.add(ApiListingResourceJSON.class);
        resources.add(ResourceListingProvider.class);
        resources.add(MyServiceResource.class);
        return resources;
    }

    @Override
    public Set<Object> getSingletons()
    {
        return singletons;
    }
}

这是将上述所有内容联系在一起的服务器代码：

public class MyService {
    private Server server;

    public MyService() {
    }

    public void start() throws Exception {
        server = new Server();
        SelectChannelConnector connector = new SelectChannelConnector();
        connector.setPort(8002);
        server.addConnector(connector);

        // Setup web handler
        final ResourceHandler webResourceHandler = new ResourceHandler();
        webResourceHandler.setDirectoriesListed(false);
        webResourceHandler.setWelcomeFiles(new String[]{"index.html"});
        webResourceHandler.setResourceBase("webapp");

        // Create servlet context
        final ServletContextHandler servletContext = new ServletContextHandler(ServletContextHandler.SESSIONS);
        servletContext.addEventListener(new DefaultResteasyBootstrap());
        servletContext.setContextPath("/");

        // Setup Swagger handlers
        servletContext.addServlet(new ServletHolder(new SwaggerJaxrsConfig()), "");

        // Add MyService Servlet
        final ServletHolder servletHolder = new ServletHolder(new HttpServletDispatcher());
        servletHolder.setInitParameter("javax.ws.rs.Application", MyServiceResource.class.getName());
        servletContext.addServlet(servletHolder, "/*");

        // Add Admin Servlet
        final ServletHolder adminServletHolder = new ServletHolder(new HttpServletDispatcher());
        servletContext.addServlet(adminServletHolder, "/admin/*");

        // Add Admin Servlets
        servletContext.addServlet(new ServletHolder(new PingServlet()), "/ping");
        servletContext.addServlet(new ServletHolder(new ThreadDumpServlet()), "/threadDump");

        final HandlerList handlers = new HandlerList();
        handlers.setHandlers(new Handler[]{
                webResourceHandler,     // Web handler
                servletContext,         // Servlet handler
                new DefaultHandler()}); // Default handler returns 404 (NOT FOUND) for anything else

        server.setHandler(handlers);
        server.start();
        server.join();
    }
}
