加载项没有响应。等或取消？

Question

我正在尝试使用atlassian-connect-play-java创建一个简单的HelloWorld加载项：

我的控制器：

package controllers;
import views.html.*;
import com.atlassian.connect.play.java.controllers.AcController;
import com.google.common.base.Supplier;
import play.mvc.Controller;
import play.mvc.Result;
public class Application extends Controller {
     public static Result index()
    {
        return AcController.index(home(), descriptor());
    }
     private static Supplier<Result> descriptor()
    {
        return new Supplier<Result>()
        {
            @Override
            public Result get()
            {
                return AcController.descriptor();
            }
        };
    }
    private static Supplier<Result> home()
    {
        return new Supplier<Result>()
        {
            @Override
            public Result get()
            {
                return ok(index.render("Hello"));
            }
        };
    }
}

我的路线档案：

GET / controllers.Application.index()
GET /assets/*file controllers.Assets.at(path="/public", file)
-> / ac.Routes

我的索引：scala.html文件：

@(message: String)
@main("Welcome to Play") {
        <p>@message</p>

}

我的main.scala.html文件：

@(title: String)(content: Html)
<!DOCTYPE html>
<html>
    <head>
        <title>@title</title>

        <script src="http://localhost:1990/confluence/atlassian-connect/all.js" type="text/javascript"></script>

    </head>
    <body>
        <div class="ac-content">
        <p>@content</p>
    </div>

    </body>
</html>
