Question

每当我在spring数据休息中使用自定义序列化程序时，它会添加一个＆＃34;内容＆＃34;包装返回对象的属性，如：

{
   "content":{
      object properties...
   },
   _links: {
   }
}

编辑：添加配置类

@Configuration
public class JacksonCustomizations {

    @Bean
    public Module rateModule() {
        return new RateModule();
    }

    @SuppressWarnings("serial")
    static class RateModule extends SimpleModule {

        public RateModule() {
            setMixInAnnotation(Package.class, RateModule.PackageMixin.class);
            setMixInAnnotation(Section.class, RateModule.SectionMixin.class);
            setMixInAnnotation(MainPart.class, RateModule.MainPartMixin.class);
            setMixInAnnotation(SubPart.class, RateModule.SubPartMixin.class);

            addSerializer(MaintenanceTask.class, new MaintenanceTaskSerializer());

            addDeserializer(Package.class, new PackageDeserializer());
            addDeserializer(Section.class, new SectionDeserializer());
            addDeserializer(MainPart.class, new MainPartDeserializer());
            addDeserializer(MaintenanceTask.class, new MaintenanceTaskDeserializer());
        }

        @JsonAutoDetect(fieldVisibility=Visibility.NONE, getterVisibility=Visibility.NONE, isGetterVisibility=Visibility.NONE)
        static abstract class PackageMixin {

            @JsonProperty("name") public abstract String getName();
            @JsonProperty("sections") public abstract List<Section> getSections();
        }

        @JsonAutoDetect(fieldVisibility=Visibility.NONE, getterVisibility=Visibility.NONE, isGetterVisibility=Visibility.NONE)
        static abstract class SectionMixin {

            @JsonProperty("id") public abstract Long getId();
            @JsonProperty("name") public abstract String getName();
        }

        @JsonAutoDetect(fieldVisibility=Visibility.NONE, getterVisibility=Visibility.NONE, isGetterVisibility=Visibility.NONE)
        static abstract class MainPartMixin {

            @JsonProperty("name") public abstract String getName();
            @JsonProperty("subparts") public abstract List<SubPart> getSubParts();
        }

        @JsonAutoDetect(fieldVisibility=Visibility.NONE, getterVisibility=Visibility.NONE, isGetterVisibility=Visibility.NONE)
        static abstract class SubPartMixin {

            @JsonProperty("id") public abstract Long getId();
            @JsonProperty("name") public abstract String getName();
        }

        static class MaintenanceTaskSerializer extends JsonSerializer<MaintenanceTask> {

            @Override
            public void serialize(final MaintenanceTask value, final JsonGenerator gen, final SerializerProvider serializers)
                    throws IOException, JsonProcessingException {
                gen.writeStartObject();
                gen.writeNumberField("id", value.getId());
                gen.writeStringField("maintenanceRequirementId", value.getMaintenanceRequirementId());
                gen.writeStringField("type", value.getType().toString());
                gen.writeStringField("title", value.getTitle());
                gen.writeStringField("description", value.getDescription());
                gen.writeStringField("note", value.getNote());
                gen.writeStringField("effectivity", value.getEffectivity());
                gen.writeNumberField("procedureReference", value.getReferenceTask().getId());
                gen.writeNumberField("aircraftModel", value.getAircraftModel().getId());
                gen.writeNumberField("packageId", value.getPack().getId());
                gen.writeNumberField("sectionId", value.getSection().getId());
                gen.writeStringField("taskType", value.getTaskType().toString());
                gen.writeEndObject();
            }

        }
    }
}

但是当我使用没有自定义序列化程序的spring数据休息序列化时，不会插入该属性。

如何阻止此属性显示？

这是一个已知问题。

此处有报道：https://jira.spring.io/browse/DATAREST-504
该问题指向此堆栈溢出问题：Different JSON output when using custom json serializer in Spring Data Rest

将内容属性添加到序列化
