Question

我对角度js很新，并希望学习角度js以应用于我们的项目。早些时候我们正在使用gwt-rpc和谷歌应用引擎。现在我们想要使用角度js而不是gwt。我从git hub下载了gae angularjs留言簿项目但是我无法在我的eclipse中设置它，因为它在注释中显示错误（@ Path，@ Get），如下所示。我已经安装了maven，但它仍然显示出一些错误。

以下链接包含留言簿项目。 https://github.com/GoogleCloudPlatform/appengine-angular-guestbook-java

@Path("/guestbook")
public class GuestbookResource {

  private final Logger logger = Logger.getLogger(GuestbookResource.class.getName());

  private List<Greeting> getGreetings(String guestbookName) {
    List<Greeting> greetings = new ArrayList<Greeting>();
    DatastoreService datastoreService = DatastoreServiceFactory.getDatastoreService();
    Key guestbookKey = KeyFactory.createKey("Guestbook", guestbookName);
    Query query =
        new Query("Greeting", guestbookKey).addSort("date", Query.SortDirection.DESCENDING);
    List<Entity> greetingEntities = datastoreService.prepare(query).asList(FetchOptions.Builder
        .withLimit(10));
    for (Entity greeting : greetingEntities) {
      greetings.add(Greeting.fromEntity(greeting));
    }
    return greetings;
  }

  @GET
  @Path("/{guestbookName}")
  @Produces(MediaType.APPLICATION_JSON)
  public GuestbookResponse getGuestbookData(
      @DefaultValue("default") @PathParam("guestbookName") final String guestbookName) throws
      Exception {
    return new GuestbookResponse(guestbookName, getGreetings(guestbookName),
        UserServiceInfo.get("/"));
  }

  @POST
  @Path("/{guestbookName}")
  @Produces(MediaType.APPLICATION_JSON)
  @Consumes(MediaType.APPLICATION_JSON)
  public GuestbookResponse signGuestbook(
      @DefaultValue("default") @PathParam("guestbookName") final String guestbookName,
      final Map<String, String> postData) {
    UserService userService = UserServiceFactory.getUserService();
    DatastoreService datastoreService = DatastoreServiceFactory.getDatastoreService();
    Key guestbookKey = KeyFactory.createKey("Guestbook", guestbookName);
    // We set the above parent key on each Greeting entity in order to make the queries strong
    // consistent. Please Note that as a trade off, we can not write to a single guestbook at a
    // rate more than 1 write/second.
    String content = postData.get("content");
    if (content != null && content.length() > 0) {
      Date date = new Date();
      Entity greeting = new Entity("Greeting", guestbookKey);
      greeting.setProperty("user", userService.getCurrentUser());
      greeting.setProperty("date", date);
      greeting.setProperty("content", content);
      datastoreService.put(greeting);
    }
    return new GuestbookResponse(guestbookName, getGreetings(guestbookName), null);
  }
}

对于AngularJS，最好使用带有插件的WebStorm进行自动完成和远程调试

Answer 2

请考虑使用以下列出的其中一个插件： http://maven.apache.org/eclipse-plugin.html

IntelliJ IDEA也对maven有很好的支持。使用IntelliJ可能是另一种选择，但这取决于您的口味。
