RESTful伺服

Question

我想在java上创建RESTful web服务，我选择了并得到了下面的代码。

@Path("/message")
public class Rest_test {

    @Context
    @SuppressWarnings("unused")
    private UriInfo context;

    /**
     * Default constructor. 
     */
    public Rest_test() {
        // TODO Auto-generated constructor stub
    }

    /**
     * Retrieves representation of an instance of Rest_test
     * @return an instance of String
     */
    @GET
    @Produces("application/xml")
    public String getXml() {
        // TODO return proper representation object
        return "sdfgdsd";
    }

    /**
     * PUT method for updating or creating an instance of Rest_test
     * @param content representation for the resource
     * @return an HTTP response with content of the updated or created resource.
     */
    @PUT
    @Consumes("application/xml")
    public void putXml(String content) {
    }

}

为了测试我的应用程序，我使用程序邮递员，并从这个广告localhost:8080/test/rest/message调用我的服务器，但我总是有相同的页面HTTP状态404 -没有找到。请帮帮我

评论是正确的！您应该调用: localhost:8080/nameOfYourService/rest/message

我也有一个TestWebService，不能突然调用它。

我创建了一个本地客户端应用程序并使用了一个httpURLconnection：

private class yourTestApp {
....
public static void getStringOrWhatEver() {
    try {
        URL url = new URL("http://localhost:8080/<nameOfYourService>/rest/message");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("Accept", "application/xml");

        if (conn.getResponseCode() != 200) {
            throw new RuntimeException("Failed : HTTP error code : "
                    + conn.getResponseCode());
        }

        BufferedReader br = new BufferedReader(new InputStreamReader(
                (conn.getInputStream())));

        String output;
        System.out.println("...and the message is: ");
        while ((output = br.readLine()) != null) {
            System.out.println(output);
        }
        System.out.println(".... End of content\n");
        conn.disconnect();

    } catch (MalformedURLException ex) {
        System.err.println("MalformedURLException, " + ex);
    } catch (IOException ex) {
        System.err.println("IOException, " + ex);
    }
}
....
}
