Question

对不起，标题不是很明确......在我的项目模型中，我有一个Product实体可以与其他产品相关联，但我不知道如何注释它。目前，我已经这样做了：

    @XmlRootElement(name = "product")
    @XmlType(propOrder = { "barCode", "productName", "price", "brand", "description", "reviews", "photos", "videos", "associated" })
    @XmlAccessorType(XmlAccessType.FIELD)
    public class Product {
        @XmlAttribute(name = "id")
        private Long            productId;
        private String          barCode;
        private String          productName;
        private Double          price;

        @XmlElementWrapper(name = "photos")
        @XmlElement(name = "photo", type = String.class)
        private List<String>    photos;

        @XmlElementWrapper(name = "videos")
        @XmlElement(name = "video", type = String.class)
        private List<String>    videos;

        private String          brand;
        private String          description;

        @XmlElementWrapper(name = "reviews")
        @XmlElement(name = "review", type = Review.class)
        private List<Review>    reviews;

        @XmlElementWrapper(name = "associated")
        @XmlElement(name = "product", type = Product.class)
        private List<Product>   associated;

        // with constructor, getters and setters not annotated
   }

目前，由于循环引用，此映射无效。我希望有类似的东西：

<product id="1">
   <barCode>123456789</barCode>
   <productName>Product 1</productName>
   <price>100.0</price>
   <brand>Brand 1</brand>
   <description>Description 1</description>
   <reviews/>
   <photos/>
   <videos/>
   <associated>
      <product id="2">
         <barCode>987654321</barCode>
         <productName>Product 2</productName>
         <price>500.0</price>
         <brand>Brand 2</brand>
         <description>Description 2</description>
      </product>
   </associated>
</product>

我的意思是没有地图photos，videos，reviews和associated，是否可能？我希望我很清楚，如果不是问，我会详细解释一下！

如果要排除映射字段，请使用@XmlTransient（适用于处理循环引用）
