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

Question

我面临以下问题，但找不到解决方案。

我的堆栈跟踪位于此处:

ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-2) RESTEASY002010: Failed to execute: javax.ws.rs.NotFoundException: RESTEASY003210: Could not find resource for full path: http://localhost:8080/myProjectName

这是我的 web.xml

        </login-config>

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

应用类:

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

带有服务的类

@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，当我运行应用程序时，我收到此错误(堆栈跟踪)，如下网址:http://localhost:8080/myProjectName

但是当我尝试运行如下服务时:

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

工作正常。

我错过了什么？

我尝试阅读 stackoverflow 中的其他解决方案和 RESTEASY 文档，但我找不到解决方案。 有人遇到过这样的问题吗？

Answer 1

我认为您的错误消息不是致命的。您收到该错误是因为您没有映射根 URL (/)。为了避免这种情况，您可以将根 URL 映射到某些内容，例如:

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

已编辑:不要将根 URL 映射到同一个类上，而是将其放在另一个类上，因为您的 PageServiceREST 已经指定了文件夹 路径。
