Question

抱歉，標題不是很明確...在我的Projet模型中，我有一個Product實體，該實體可以與其他產品關聯，但是我不知道如何對其進行注釋。 目前，我已經做到了：

    @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
   }

當前，由於循環引用，此映射不起作用。 我想要一些類似的東西：

<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>

我的意思是在地圖中沒有photos ， videos ， reviews和associated ，這可能嗎？ 我希望我已經足夠清楚了，如果不僅僅是問我，我會詳細解釋！

如果要排除映射的字段，請使用@XmlTransient（適用於處理循環引用）
