我在把JSON派到泽西岛理工学院服务方面存在问题,GET正在完美地工作,但POST似乎trick。 现在,我一直在处理这个问题,迄今没有解决办法。 任何帮助都受到高度赞赏!

似乎无法找到U RL来派 j子? 这里,PeBug conole显示:

    POST http://localhost:9998/data 400 Bad Request

I m 做以下工作:

<button id= btn  value="knapp" name="knapp" />
    <script type="text/javascript">
    $( #btn ).click(function(){
        $.ajax({
            url:  /data ,
            type:  POST ,
            contentType:  application/json ,
            data: {name:"Tony"},
            dataType:  json 
        });
    })
</script>

Javabean同@XmlRootElement:

@XmlRootElement
public class StatusBean {
    private String name;

    public StatusBean() {
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

资源方法:

@Path("/data")
public class PostData {
    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public StatusBean post(StatusBean sb) {
        System.out.println(sb);
        return sb;
    }
}

服务器,与Grezzly建立:

public class Main {
    public static final URI BASE_URI = getBaseURI();

    public static void main(String[] args) throws IOException {
        HttpServer httpServer = startServer();

        Map<String,String> initParams = new HashMap<String, String>();
        initParams.put("com.sun.jersey.config.property.packages", "server");
        SelectorThread selector = GrizzlyWebContainerFactory.create("http://localhost:9998/", initParams );

        System.out.println(String.format("Jersey app started with WADL available at "
                + "%sapplication.wadl
Try out %shelloworld
Hit enter to stop it...",
                BASE_URI, BASE_URI));

        System.in.read();
        httpServer.stop();
    }

    protected static HttpServer startServer() throws IOException {
        System.out.println("Starting grizzly...");

        ClassNamesResourceConfig rc = new ClassNamesResourceConfig(PostData.class);

//        rc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);

        HttpServer server = GrizzlyServerFactory.createHttpServer(BASE_URI, rc);

        server.getServerConfiguration().addHttpHandler(new StaticHttpHandler(new File(".").getAbsolutePath()), "/static");

        return server;
    }

    private static int getPort(int defaultPort) {
        String port = System.getProperty("jersey.test.port");
        if (null != port) {
            try {
                return Integer.parseInt(port);
            } catch (NumberFormatException e) {
            }
        }
        return defaultPort;
    }

    private static URI getBaseURI() {
        return UriBuilder.fromUri("http://localhost/").port(getPort(9998)).build();
    }
}
