我做了一些轻微的缩进调整，你的dsm配置文件工作得很好。

输出：

  "agency" : "Agent",

    "rate" : 1
  } ],
  "categories" : [ {
    "id" : 398,
    "parentId" : 198,
    "name" : "Lorum Ipsum"
  }, {
    "id" : 409,
    "parentId" : null,
    "name" : "Uncategorized"
  } ],
  "deliveryOptions" : null,
  "offers" : [ {
    "id" : "2016",
    "available" : true,

    "price" : 35.0,
    "currencyId" : "USD",
    "categoryId" : "168",
  }, {
    "id" : "2017",
    "available" : true,
    "type" : "vendor.model",
    "url" : "https://ms.com/id/2",
    "price" : 250.0,
    "currencyId" : "USD",
    "categoryId" : "201",

  } ]
}

这是我用来测试它的代码：

@Test
public void dsmParsing() throws IOException {

    InputStream is = new FileInputStream("src/main/resources/dsm.yml");

    DSMBuilder builder = new DSMBuilder(is);
    DSM dsm = builder.setType(DSMBuilder.TYPE.XML).create(Shop.class);
    Shop shop = (Shop) dsm.toObject(new File("src/main/resources/shop.xml"));

    ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();

    System.out.println(ow.writeValueAsString(shop));
}

要回答有关具有属性的嵌套元素的问题，必须考虑到在使用此定义时：

categories:
  type: array
  path: categories/category

当你定义 fields 您将描述元素 <category> .
在下面的示例中，属性 id 以及 parentId 将在 fields 段作为属性，但得到实际值 category 元素，则需要引用当前路径 ./ . 如果有子元素，只需在 fields 段。
xml格式

<categories>
   <category id="398" parentId="198">Lorum Ipsum</category>
 </categories>

需求侧管理

categories:
  type: array
  path: categories/category
  fields:
    name: ## you could call it 'value' or whatever you want
      path: ./
    id:
      xml:
        attribute: true
    parentId:
      xml:
        attribute: true

下一个例子很有趣：
xml格式

<offers attr1="abc" attr2="def">
    <offer id="2016" available="true">
        <url>https://ms.com/id/1</url>
    </offer>
</offers>

首先，您需要另一个pojo来正确表示 offers 及其属性：
商店

public class Shop {
  ...
  OffersList offers; // this attribute's name needs to match the one used in the dsm descriptor
}

新类报价表

public class OffersList {
  String attr1;
  String attr2;
  List<Offers> offer; // this attribute's name needs to match the one used in the dsm descriptor
}

最后，dsm将如下所示：

offers: ## name should match with Shop's attribute 'offers' (OffersList)
  type: object ## now offers is an object, is mandatory to define 'fields'
  path: offers  ## focus is on the <offers> element
  fields:
    attr1:
      xml:
        attribute: true
    attr2:
      xml:
        attribute: true
    offer:   ## name should match with OffersList's attribute 'offer'
      type: array
      path: ../offers/offer  ## will go back a level to indicate <offers> <offer> should be parsed as an array
      fields:
        id:
          xml:
            attribute: true
        available:
          xml:
            attribute: true
        url:
          path: url

输出

"offers" : {
    "attr1" : "abc",
    "attr2" : "def",
    "offer" : [ {
      "id" : "2016",
      "available" : true,
      "url" : "https://ms.com/id/1",
    } ]
  }
