XML映射到XML产生重复的标签

输入采样：XML映射到XML产生重复的标签

{ 
    "InventoryDetails" : { 
    "Inventory" : { 
     "Details" : { 
     "Category" : "Fruits", 
     "Type" : "Perishable" 
     }, 
     "Properties" : { 
     "OptField" : [ { 
      "Name" : "Apple", 
      "Value" : "Red" 
     }, { 
      "Name" : "Orange", 
      "Value" : "Orange" 
     }, { 
      "Name" : "Grapes", 
      "Value" : "Green" 
     } 
    ] 
     } 
    } 
    } 
}

我映射JSON来POJO，并试图将POJO转换为使用XML映射为XML。

没有为这种转换，无需转换JSON直接XML格式的要求，所以我一定要坚持下去，因为我们转换成XML

之前有一些转型过程但是，当我这样做，我可以看到根元素标签打印两次，有人可以帮我解决这个问题。

输出

<InventoryDetails> 
    <InventoryDetails> 
     <Inventory> 
      <Details> 
       <Category>Fruits</Category> 
       <Type>Perishable</Type> 
      </Details> 
      <Properties> 
       <OptField> 
        <Name>Apple</Name> 
        <Value>Red</Value> 
       </OptField> 
       <OptField> 
        <Name>Orange</Name> 
        <Value>Orange</Value> 
       </OptField> 
       <OptField>

哪里是你的POJO？ –

用POJO更新，并测试代码 – jasminemullai

你有没有在'InventoryDetails'类上试过'@ JacksonXmlRootElement'？ –

从here开始默认使用简单的类名作为根元素。

为了克服这一remove从输入JSON对象包围：

{ 
"Inventory" : { 
    "Details" : { 
    "Category" : "Fruits", 
    "Type" : "Perishable" 
    }, 
    "Properties" : { 
    "OptField" : [ { 
     "Name" : "Apple", 
     "Value" : "Red" 
    }, { 
     "Name" : "Orange", 
     "Value" : "Orange" 
    }, { 
     "Name" : "Grapes", 
     "Value" : "Green" 
    } 
    ] 
    } 
} 
}
