xxx 类不包含当 xxx 成为 Tapestry 服务时自动构建所需的公共构造函数

本文介绍了xxx 类不包含当 xxx 成为 Tapestry 服务时自动构建所需的公共构造函数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我发现了 Tynamo 团队在 Tapestry 和 Resteasy 之间进行的精彩整合工作.

I'm discovering the wonderful integration work made by Tynamo's team between Tapestry and Resteasy .

我正在尝试在网络服务上激活 Liveclass Reloading.根据文档说:

I'm trying to activate Liveclass Reloading on webservices. As per doc says :

您唯一需要做的就是为您的课程启用实时课程重新加载REST 服务是将它们绑定为常规 Tapestry IoC 服务和将它们贡献给 javax.ws.rs.core.Application.class.阅读更多关于服务实现重新加载的工作原理:http://tapestry.apache.org/reload.html

这是一个来自tapestry-resteasy 测试套件的示例.

Here is an example from the tapestry-resteasy test suite.

public static void bind(ServiceBinder binder)
{
    binder.bind(ReloadableEchoResource.class, ReloadableEchoResourceImpl.class);
}

@Contribute(javax.ws.rs.core.Application.class)
public static void configureRestResources(Configuration<Object> singletons, ReloadableEchoResource reloadableEchoResource)
{
    singletons.add(reloadableEchoResource);
}

我自己的作品

这正是我正在做的(嗯……嗯，至少我相信它是；D):

My Own Work

This is exactly what I'm doing (well ... hmmm at least I believe that it is ;D):

public static void bind(ServiceBinder binder)
{
    binder.bind(PushMessageService.class, GCMPushMessageServiceImpl.class);
    binder.bind(UserService.class, HibernateUserServiceImpl.class);
    binder.bind(IUserResource.class, UserResourceImpl.class);

}

/**
 * Contributions to the RESTeasy main Application, insert all your RESTeasy singletons services here.
 */
@Contribute(javax.ws.rs.core.Application.class)
public static void configureRestResources(Configuration<Object> singletons, IUserResource userResource)
{
    singletons.add(userResource);
}

我的界面

@Path("/user")
public interface IUserResource {

    /**
     * Lecture de tous les utilisateurs
     *
     * @return une List des utilisateurs existants
     */
    @GET
    @Produces("application/json")
    public abstract List<User> getAllDomains();

错误

但是当我启动我的应用程序时，我收到了这条消息:

Error

But when I start my app, I obtain this message :

HTTP ERROR 500

Problem accessing /user. Reason:

Exception constructing service 'ResteasyRequestFilter': Error building service proxy for service 'Application' (at org.tynamo.resteasy.Application(Collection) (at Application.java:14) via org.tynamo.resteasy.ResteasyModule.bind(ServiceBinder) (at ResteasyModule.java:31)): Error invoking service contribution method org.tynamo.resteasy.ResteasyModule.javaxWsRsCoreApplication(Configuration, ObjectLocator, ResteasyPackageManager, ClassNameLocator): Class com.sopragroup.ecommerce.mobile.rest.IUserResource does not contain a public constructor needed to autobuild.

Caused by:

    at org.apache.tapestry5.ioc.internal.services.JustInTimeObjectCreator.createObject(JustInTimeObjectCreator.java:54)

这很像自动绑定不起作用(我确实认为是这样).显然，当我尝试不创建界面和绑定时，它就像一个魅力.

It's quite like the autobinding don't works (indeed I do think it is).Obviously, when I try to without creating an interface and binding, it works like a charm.

谁能给我一个线索?
