为什么我的子资源不匹配？

Question

我无法获得子资源的工作，这是我的错误

WARN [org.jboss.resteasy.core.ExceptionHandler] (default task-1) failed to execute: javax.ws.rs.NotFoundException: Could not find resource for full path: http://127.0.0.1:8080/NornLM/individuals/f86e3400-5f56-4b28-af44-69a2ccfd908e/activities/a9da4e17-2ca4-4c02-a9ff-71638a92c318 

和其他一些有趣的日志数据

这里是我的基本资源

package com.lm.activity.rest; 

import com.lm.activity.IndividualBuilder; 
import com.lm.infrastructure.Regex; 
import javax.enterprise.context.RequestScoped; 
import javax.inject.Inject; 
import javax.ws.rs.Path; 
import javax.ws.rs.PathParam; 
import javax.ws.rs.container.ResourceContext; 
import javax.ws.rs.core.Context; 
import org.slf4j.Logger; 

@RequestScoped 
@Path("/individuals") 
public class IndividualsCtrlr { 

    @Path("{individual:" + Regex.UUID + "}") 
    public ActivitiesCtrlr activities(
      @PathParam("individual") IndividualBuilder ib 
    ) { 
     log.debug("Individual Activities"); 
     ActivitiesCtrlr ctrl 
       = resourceContext.getResource(ActivitiesCtrlr.class); 

     ctrl.setIndividual(ib.build()); 

     return ctrl; 
    } 

    @Context 
    ResourceContext resourceContext; 

    @Inject 
    Logger log; 
} 

这里是我的ActivtiesCtrlr

package com.lm.activity.rest; 

import com.lm.activity.ActivitiesRepo; 
import com.lm.activity.Activity; 
import com.lm.activity.BuilderActivityPermaURI; 
import com.lm.activity.DTOActivity; 
import com.lm.activity.Individual; 
import com.lm.infrastructure.Regex; 
import java.time.LocalDate; 
import java.util.List; 
import java.util.Map; 
import java.util.Objects; 
import java.util.Set; 
import java.util.UUID; 
import java.util.stream.Collectors; 
import javax.enterprise.context.RequestScoped; 
import javax.inject.Inject; 
import javax.ws.rs.Consumes;

import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 
import javax.ws.rs.core.UriInfo; 
import org.slf4j.Logger; 

// I've tried removing Path/RequestScoped from this and moving it to the base resource 
@Path("activities") 
@RequestScoped 
@Produces(MediaType.APPLICATION_JSON) 
@Consumes(MediaType.APPLICATION_JSON) 
public class ActivitiesCtrlr { 

    @GET 
    @Path("current") 
    public Response current(
      @Context final UriInfo uriInfo 
    ) { 
     final Activity current = repo.getActivityInventory(individual) 
       .toDo(LocalDate.now()) 
       .current(); 

     final BuilderActivityPermaURI uriBuilder 
       = new BuilderActivityPermaURI(uriInfo.getBaseUriBuilder()); 

     uriBuilder.fromActivity(current); 

     responseBuilder = Response.temporaryRedirect(uriBuilder.build()); 

     return responseBuilder.build(); 
    } 

    @GET 
    @Path("{activity:" + Regex.UUID + "}") 
    public Response get(
      @PathParam("activity") final UUID activityId 
    ) { 
     try { 
      final Activity current 
        = repo.getActivityInventory(individual) 
        .toDo(LocalDate.now()) 
        .current(); 

      responseBuilder = Response.ok(current.toDTO()); 
     } 
     catch (Exception e) { 
      log.warn("GET: ", e); 
     } 


     return responseBuilder.build(); 
    } 

    @PUT 
    @Path("{activity:" + Regex.UUID + "}") 
    public Response putActivity(
     @Context final UriInfo uri, 
     @PathParam("activity") final UUID activityId, 
     final DTOActivity dtoa 
    ) { 
     final Activity activity 
       = repo 
       .instanceFromDTO(dtoa) 
       .associateId(activityId) 
       .setIndividual(individual) 
       .build(); 

     try { 
      if (repo.add(activity)) { 
       responseBuilder 
         = Response.created(uri.getAbsolutePath()) 
        .entity(activity.toDTO()); 
      } 
      else { 
       responseBuilder = Response.ok(activity.toDTO()); 
      } 
     } 
     catch (Exception e) { 
      log.error("add to repository error: {}", e); 
      responseBuilder = Response.serverError(); 
     } 

     return responseBuilder.build(); 
    } 

    void setIndividual(final Individual individual) { 
     Objects.requireNonNull(individual); 
     this.individual = individual; 
    } 

    Individual individual; 

    Response.ResponseBuilder responseBuilder; 

    @Inject 
    ActivitiesRepo repo; 

    @Inject 
    Logger log; 
} 

我使用此代码来构建请求uri，baseResource和subResource是合适的类。

URI uri = UriBuilder 
     .fromUri(deploymentURI) 
     .path(baseResource) 
     .path(baseResource, "activities") 
     .path(subResource) 
     .path(subResource, "putActivity") 
     .build(randomUUID(), randomUUID()); 

我还证实，如果我在ActivitiesCtrlr类改变@Path到下面的路径匹配。这证实了与Regex.UUID

@Path("/individuals/{individual:" + Regex.UUID + "}/activities") 

虽然没有问题，只是要确定

package com.lm.infrastructure; 

public class Regex { 
    public static final String UUID 
      = "[\\p{XDigit}]{8}" 
      + "(-[\\p{XDigit}]{4}){3}" 
      + "-[\\p{XDigit}]{12}"; 
} 

这里的实际提交HTTP

PUT /NornLM/individuals/e672cd0c-729d-4128-a118-aaf7fd8675d7/activities/251453ff-12d1-4a38-8b5a-00bf2557584b HTTP/1.1 
Content-Length: 57 
Content-Type: application/json; charset=UTF-8 
Host: 127.0.0.1:8080 
Connection: Keep-Alive 
User-Agent: Apache-HttpClient/4.3.2 (java 1.5) 
Accept-Encoding: gzip,deflate 

{"completed":false,"created":null,"description":"testme"} 

我在做什么错？

Answer 1

您的ActivitiesCtrlr类是JAX-RS根资源，而不是子资源。你可以尝试删除这个类的@Path注释和修改@Path注释上ActivitiesCtrlr#get()到这样的事情：

@GET 
@Path("/activities/{activity:" + Regex.UUID + "}") 
public Response get(
     @PathParam("activity") final UUID activityId 
) { 
    ... 
} 

我希望它会工作。
