Question

在我的yaml定义中，对象没有连接。它是null。我没有看到问题：

人：

@Entity
@Table(name="person")
public class Person extends Model {

    @Id
    @Constraints.Required
    @Formats.NonEmpty
    public Long id;
...

LifeCycleEvent：

@Entity
@Table(name="lifecycleevent")
public class LifeCycleEvent extends Model {

@Id
@Constraints.Required
@Formats.NonEmpty
public Integer id;

@ManyToOne
@Constraints.Required
public Person author;

INIT-data.yml

lifecycleevent:

- !!models.LifeCycleEvent
    title:      Lorem Away 1
    text:       Lorem ipsum dolor sit amet, consectetuer a ...
    read:       1
    creationDateTime:   2010-02-11 11:02:57
    publishingDateTime: 2012-01-12 07:30:00
    lastEditedDateTime: 2013-03-23 15:22:00
    author:     !!models.Person
                    id: 1

测试

    LifeCycleEvent lifeCycleEvent = LifeCycleEvent.findById(1);
    assertThat(lifeCycleEvent).isNotNull();
    assertThat(lifeCycleEvent.id).isEqualTo(1);
    assertThat(lifeCycleEvent.author).overridingErrorMessage("Author of " + lifeCycleEvent + " can not be null").isNotNull();

问题是（当然）全局设置中Ebean.save（）的顺序很重要

Yaml中的多对一关系
