我正在使用 Jackson XmlMapper 读取 XML 字符串并将其转换为 JsonString。我的 XML 文件是:

<root>
<catalog>
   <book id="bk101">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications 
      with XML.</description>
   </book>
   <book id="bk105">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications 
      with XML.</description>
   </book>
   <book id="bk114">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications 
      with XML.</description>
   </book>
</catalog>
</root>

我为转换编写的代码是:

XmlMapper xmlMapper = new XmlMapper();
List entries = xmlMapper.readValue(file, List.class);
ObjectMapper jsonMapper = new ObjectMapper();
String json = jsonMapper.writeValueAsString(entries);

我作为输出得到的 Json 字符串是:

{
  "id": "569df9c1e4b0e505eb9fb913",
  "json": [
    {
      "book": {
        "id": "bk114",
        "author": "Gambardella, Matthew",
        "title": "XML Developer's Guide",
        "genre": "Computer",
        "price": "44.95",
        "publish_date": "2000-10-01",
        "description": "An in-depth look at creating applications \n          with XML."
      }
    }
  ],
  "fileType": "xml"
}

只有最后一本书被映射到 Json 字符串。 回答一个类似的问题,建议将 xml 字符串读入它的对象类而不是通用列表类。但是我试图处理的 XML 文件是通用的,没有固定的 POJO 表示。我该如何处理这个问题?

谢谢!

解决了这个问题。使用 org.json.XML toJsonObject 函数将 XML 转换为 JSON。这个 XML 解析器能够解析复杂的 XML 文件,比如问题中的那个。
