Java 为什么使用quarkus华丽、hibernate和jsonb的反序列化失败了？

我想玩一下hibernate、panache和quarkus。我想构建一个“跟踪”api，其中一个人可以有几个跟踪，但一个跟踪只能由一个人拥有。但我面临一个反序列化错误

假设我想发布以下内容：

curl --location --request POST 'localhost:8080/trace' \
--header 'Content-Type: application/json' \
--data-raw '{
    "traceOwner": "AtestOwner",
    "participants": ["Karl", "John"],
    "place": "10101, TestCity, TestStreet 25",
    "startTime": "2016-07-20T23:07:41.907+02:00[Europe/Berlin]",
    "stopTime": "2016-07-27T23:07:45.807+02:00",
    "comment": "TestComment"
}'

我得到以下错误：

javax.ws.rs.ProcessingException: RESTEASY008200: JSON Binding deserialization error: javax.json.bind.JsonbException:
Unable to deserialize property 'traceOwner' because of: Error deserialize JSON value into type: class
de.test.Person.

在日志中：

2020-07-27 10:48:12,597 SEVERE [org.ecl.yas.int.Unmarshaller] (executor-thread-1) Unable to deserialize property 'traceOwner' because of: Error deserialize JSON value into type: class de.test.Person.

我的实体如下所示：

import java.time.ZonedDateTime;
import java.util.List;

import javax.persistence.Column;
import javax.persistence.ElementCollection;
import javax.persistence.Entity;
import javax.persistence.ManyToOne;

import io.quarkus.hibernate.orm.panache.PanacheEntity;

@Entity
public class Trace extends PanacheEntity {
  @ManyToOne
  public Person traceOwner;
  @ElementCollection
  public List<String> participants;
  public String place;
  @Column(columnDefinition = "TIMESTAMP WITH TIME ZONE")
  public ZonedDateTime startTime;
  @Column(columnDefinition = "TIMESTAMP WITH TIME ZONE")
  public ZonedDateTime stopTime;
  public String comment;

  public String toString() {
    return String.format("%s, [%s, %s], %s, %s, %s", this.traceOwner, this.participants.get(0),
        this.participants.get(1), this.place, this.startTime, this.stopTime, this.comment);
  }
}

  @POST
  @Produces(MediaType.APPLICATION_JSON)
  @Consumes(MediaType.APPLICATION_JSON)
  public Response createTrace(@Valid Trace trace) {
    try {
      LOG.info(trace);
      transaction.begin();
      trace.persist();
      transaction.commit();
    } catch (NotSupportedException | SystemException | SecurityException | IllegalStateException | RollbackException
        | HeuristicMixedException | HeuristicRollbackException e1) {
      LOG.error("Could not finish transaction to save entity", e1);
      return Response.status(HttpStatus.SC_BAD_REQUEST).build();

    }
    return Response.ok(Trace.find("startTime =?1 AND traceOwner = ?2", trace.startTime, trace.traceOwner).firstResult())
        .build();
  }

POST端点如下所示：

import java.time.ZonedDateTime;
import java.util.List;

import javax.persistence.Column;
import javax.persistence.ElementCollection;
import javax.persistence.Entity;
import javax.persistence.ManyToOne;

import io.quarkus.hibernate.orm.panache.PanacheEntity;

@Entity
public class Trace extends PanacheEntity {
  @ManyToOne
  public Person traceOwner;
  @ElementCollection
  public List<String> participants;
  public String place;
  @Column(columnDefinition = "TIMESTAMP WITH TIME ZONE")
  public ZonedDateTime startTime;
  @Column(columnDefinition = "TIMESTAMP WITH TIME ZONE")
  public ZonedDateTime stopTime;
  public String comment;

  public String toString() {
    return String.format("%s, [%s, %s], %s, %s, %s", this.traceOwner, this.participants.get(0),
        this.participants.get(1), this.place, this.startTime, this.stopTime, this.comment);
  }
}

  @POST
  @Produces(MediaType.APPLICATION_JSON)
  @Consumes(MediaType.APPLICATION_JSON)
  public Response createTrace(@Valid Trace trace) {
    try {
      LOG.info(trace);
      transaction.begin();
      trace.persist();
      transaction.commit();
    } catch (NotSupportedException | SystemException | SecurityException | IllegalStateException | RollbackException
        | HeuristicMixedException | HeuristicRollbackException e1) {
      LOG.error("Could not finish transaction to save entity", e1);
      return Response.status(HttpStatus.SC_BAD_REQUEST).build();

    }
    return Response.ok(Trace.find("startTime =?1 AND traceOwner = ?2", trace.startTime, trace.traceOwner).firstResult())
        .build();
  }

为了避免缓存问题，我打开了一个新事务，但我想这不是问题所在吧

我真的不明白为什么jsonB会抱怨反序列化以及我如何修复它。另外，在某个时刻，我希望

公共列表参与者

成为

公共列表参与者

，但这可以等到关系和反序列化工作开始。

因此，我发现我做错了什么。两件事：

使用有效的json：

请注意不同的“跟踪所有者”部分

使用

@ManyToOne（cascade=CascadeType.ALL）

也可以在持久化时更新瞬态属性

你能粘贴错误信息和stacktrace以便我们更好地了解问题吗？我附上了错误信息以及我可以从日志中收集到的信息。即使我使用

/gradlew quarkusDev--stacktrace

或

，日志看起来也是一样的--debug

公平地说，我认为这不起作用的原因与quarkus无关（尽管我想知道如何更好地调试错误），而是我犯了一些与hibernate相关的错误
