解析为LinkedHashMap时，XmlMapper缺少root

Question

public static void main(String[] args) throws IOException {
    XmlMapper xmlMapper = new XmlMapper();
    LinkedHashMap result = xmlMapper.readValue("<root><a>1</a><b>2</b></root>", LinkedHashMap.class);
    System.out.println(result);
}

它返回：

{a=1, b=2}

如何让它保持这样的根元素：

{
   root = { 
      a = 1, 
      b = 2
   }
}

Answer 1

Please consider creating a real POJO for this use-case as maps are not supported for root elements.
