我尝试使用两种模型从REST API（宠物和媒体）获取数据。我试图通过FetchType.EAGER批注获取宠物与媒体之间的oneToMany关系，但是在编写MediaRepository时没有出现数据。如果我没有实现该文件，则媒体关系和数据会在响应中返回。

实施MediaRepository.java后，GET / pets返回：

{
  "id": 72,
  "name": "Spot",
  "description": "Annoying as hell",
  "media": [], <-- why is this here only if I don't implement MediaRepository?
  ...
}

如果未实现MediaRepository.java，则GET / pets将返回：

{
  "id": 72,
  "name": "Spot",
  "description": "Annoying as hell",
  ... (No media array in response)
}

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name="name")
    private String name;

    @Column(name="description")
    private String description;

    @OneToMany(cascade=CascadeType.ALL, mappedBy="pet", …
