错误[org.jboss.resteasy.resteasy_jaxrs.i18n]（默认任务-2）RESTEASY002010

Question

我面临以下问题，找不到解决方案来解决它。

我的堆栈跟踪到这里：

ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-2) RESTEASY002010: Failed to execute: javax.ws.rs.NotFoundException: RESTEASY: Could not find resource for full path: http://localhost:8080/myProjectName

这里是我的web.xml

     </login-config> 

    <security-role> 
     <role-name>administrator</role-name> 
    </security-role> 
</web-app> 

应用类：

@ApplicationPath("/") 
public class LauncherWebServices extends Application{ 
} 

类与服务

@Path("/folders") 
@RequestScoped 
public class PageServicesREST { 
     @GET 
    @Path("/retrievePage") 
    @Produces(MediaType.APPLICATION_JSON) 
    public Response getListPage() { 
     List<Page> list = pageBusiness.retrievePage(); 
     if (list == null) { 
      return Response.ok().entity("Liste des pages est vide").build(); 
     } 
     return Response.ok().entity(pageBusiness.retrievePage()).build(); 
    } 
} 

现在，当我运行的应用程序，我得到这个错误（堆栈跟踪）这样的网址：http://localhost:8080/myProjectName

但是，当我试图运行象下面这样的服务：

http://localhost:8080/myProjectName/folders/retrievePage 

它工作正常。

我错过了什么？

我曾尝试阅读其他解决方案在stackoverflow和文档RESTEASY但我找不到解决方案。 有没有人遇到过这样的问题？

Answer 1

您的错误信息在我看来并不是致命的。你得到这个错误是因为你没有映射你的根URL（/）。要避免这种情况，你可以映射你的根URL的东西，例如：

@Path("/") 
@RequestScoped 
public class Root { 
    @GET 
    public Response index() { 
     return Response.ok().build(); 
    } 
} 

编辑：与其在同一类的映射根URL，把它放在另一个类，因为你已经PageServiceREST指定folders路径。
