使用@JsonSerialize在Spring Data REST中隐藏HATEOAS链接

Question

我正在使用Spring Boot 2.x，Spring Data REST，Spring HATEOAS。 我有一个简单的豆子：

@Entity
public class Printer extends AbstractEntity {

    @NotBlank
    @Column(nullable = false)
    private String name;

    // Ip address or hostname
    @NotBlank
    @Column(nullable = false)
    private String remoteAddress;

    @NotNull
    @Enumerated(EnumType.STRING)
    @Column(nullable = false)
    @JsonSerialize(using = PrinterModelSerializer.class)
    private PrinterModel model;

    @NotNull
    @Column(nullable = false, columnDefinition = "BIT DEFAULT 0")
    private boolean ssl = false;

    // The store where the device is connected
    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    private Store store;

我为枚举PrinterModel添加了自定义序列化器：

public class PrinterModelSerializer extends JsonSerializer<PrinterModel> {

    @Override
    public void serialize(PrinterModel value, JsonGenerator gen, SerializerProvider serializers) throws IOException {

        gen.writeStartObject(); // {

        gen.writeStringField("key", value.toString());
        gen.writeStringField("name", value.getName());
        gen.writeBooleanField("fiscal", value.isFiscal());
        gen.writeStringField("imageUrl", value.getImageUrl());

        gen.writeEndObject(); // }

        gen.close();

    }

}

当我使用Spring Data REST存储库获取资源打印机时，我已经：

{
  "sid" : "",
  "createdBy" : "admin",
  "createdDate" : "2018-10-16T12:29:24Z",
  "lastModifiedDate" : "2018-10-16T14:12:08.671566Z",
  "lastModifiedBy" : "ab48d95f-09f3-40ba-b8ba-e6fd206a2fe6",
  "createdByName" : null,
  "lastModifiedByName" : null,
  "name" : "m30",
  "remoteAddress" : "111.222.333.456",
  "model" : {
    "key" : "EPSON_M30",
    "name" : "Epson TM-m30",
    "fiscal" : false,
    "imageUrl" : "https://www.epson.it/files/assets/converted/550m-550m/0/0/1/d/001d0815_pictures_hires_en_int_tm-m30_w_frontpaperloading_paper.tif.jpg"
  }
}

如您所见，我没有HATEOAS链接。如果我删除自定义序列化程序，那么我会得到正确的答复：

{
  "sid" : "",
  "createdBy" : "admin",
  "createdDate" : "2018-10-16T12:29:24Z",
  "lastModifiedDate" : "2018-10-16T14:12:08.671566Z",
  "lastModifiedBy" : "ab48d95f-09f3-40ba-b8ba-e6fd206a2fe6",
  "createdByName" : null,
  "lastModifiedByName" : null,
  "name" : "m30",
  "remoteAddress" : "111.222.333.456",
  "model" : "EPSON_M30",
  "ssl" : true,
  "_links" : {
    "self" : {
      "href" : "http://x.x.x.x:8082/api/v1/printers/3"
    },
    "printer" : {
      "href" : "http://x.x.x.x:8082/api/v1/printers/3{?projection}",
      "templated" : true
    },
    "store" : {
      "href" : "http://x.x.x.x:8082/api/v1/printers/3/store{?projection}",
      "templated" : true
    }
  }
}

如何防止@JsonSerialize断开HATEOAS链接？
