Question

我想有一个（嵌入式）jetty + jersey服务器，它提供REST api（“/ resource”路由上的GET和POST），但也提供一些静态内容（index.html，bundle.js on the“ /“）。我只能让/ resource部分工作 - 用curl测试GET / POST，即

curl -X POST -H 'Content-Type: application/json' -d '{"resource":"FOOBAR"}' http://localhost:8080/resource

然而，“/”路径通过此设置返回404：

public static void main(String[] args) {

        Server jettyServer = new Server(8080);

        ResourceConfig rc = new ResourceConfig();

        JSONResource resource = new JSONResource();

        rc.register(resource);

        ServletContainer sc = new ServletContainer(rc);

        ServletHolder servletHolder = new ServletHolder(sc);
        // ServletHolder servletHolder = new ServletHolder("default", new DefaultServlet());

        // static content
        servletHolder.setInitParameter("resourceBase", "./src/webapp/");

        ServletContextHandler context = new ServletContextHandler();
        context.addServlet(servletHolder, "/*");

        jettyServer.setHandler(context);

        try {

            jettyServer.start();
            jettyServer.join();

        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            jettyServer.destroy();
        }

    }

路径：

@Path("/resource")
public class JSONResource {

    Resource resource =  Resource.getInstance();

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String getStringResource() {
        return this.resource;
    }

    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    public Response putStringResource(Resource json) {

        this.resource.setResource(json.getResource());
        return Response.status(Status.OK).entity(json).build();
    }

}

资源类的完整性：

public class Resource {

    private String resource = "";

    private Resource() {
    }

    private static class Holder {
        private static final Resource INSTANCE = new Resource();
    }

    public static Resource getInstance() {
        return Holder.INSTANCE;
    }

    public String getResource() {
        return resource;
    }

    public void setResource(String resource) {
        this.resource = resource;
    }

    @Override
    public String toString() {
        return resource;
    }

}

编辑了以下每个答案

    // ---JSON RESOURCE---//

    JSONResource resource = new JSONResource();

    ResourceConfig rc = new ResourceConfig();
    rc.register(resource);

    ServletContainer sc = new ServletContainer(rc);

    ServletHolder servletHolder = new ServletHolder(sc);

    ServletContextHandler jsonResourceContext = new ServletContextHandler();
    jsonResourceContext.addServlet(servletHolder, "/*");

    // ---STATIC RESOURCE---//

    ResourceHandler staticResourceHandler = new ResourceHandler();

    staticResourceHandler.setResourceBase("./src/webapp/");

    ContextHandler staticContextHandler = new ContextHandler("/");
    staticContextHandler.setHandler(staticResourceHandler);

    // ---ADD HANDLERS---//

    HandlerList handlers = new HandlerList();

    handlers.setHandlers(new Handler[] { jsonResourceContext, //
            staticContextHandler, //
            new DefaultHandler() //
    });

    jettyServer.setHandler(handlers);

可以减少冗长吗？

Answer 1

您的服务器类只有一个静态内容处理程序。你需要一个额外的JSON东西处理程序。必须将其分配给处理程序列表。

e.g。

    HandlerList handlers = new HandlerList();
    handlers.setHandlers(new Handler[] { jsonRessourcehandler, servletContextHandler, new DefaultHandler() });
    server.setHandler(handlers);

还提供类似json的东西，你想要搜索JERSEY库/例子
