錯誤[org.jboss.resteasy.resteasy_jaxrs.i18n]（默認任務-2）RESTEASY002010

Question

我面臨以下問題，找不到解決方案來解決它。

我的堆棧跟蹤到這裏：

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

這裏是我的web.xml

    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     </login-config> 

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

應用類：

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

類與服務

@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(); 
    } 
} 

現在，當我運行的應用程序，我得到這個錯誤（堆棧跟蹤）這樣的網址：http://localhost:8080/myProjectName

但是，當我試圖運行象下面這樣的服務：

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

它工作正常。

我錯過了什麼？

我曾嘗試閱讀其他解決方案在stackoverflow和文檔RESTEASY但我找不到解決方案。 有沒有人遇到過這樣的問題？

Answer 1

您的錯誤信息在我看來並不是致命的。你得到這個錯誤是因爲你沒有映射你的根URL（/）。要避免這種情況，你可以映射你的根URL的東西，例如：

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

編輯：與其在同一類的映射根URL，把它放在另一個類，因爲你已經PageServiceREST指定folders路徑。
