Jackson parsing XML

问题

I'm trying to serialize POJO class to Amazon XML format to aggregate the date from the service.

The goal is to have an xml like:

  1. <ShipmentEventList>
  2.     <ShipmentEvent>
  3.         <ShipmentItemList>
  4.             <ShipmentItem></ShipmentItem>
  5.         </ShipmentItemList>
  6.         <AmazonOrderId>AAAA</AmazonOrderId>
  7.         <PostedDate>BBBB</PostedDate>
  8.         <MarketplaceName>CCCC</MarketplaceName>
  9.         <SellerOrderId>DDDD</SellerOrderId>
  10.     </ShipmentEvent>
  11. </ShipmentEventList>

Here are my POJO classes

ShipmentEventList

  1. public class ShipmentEventList {
  3.    @JacksonXmlElementWrapper(localName = "ShipmentEventList")
  4.    @JacksonXmlProperty(localName = "ShipmentEvent")
  5.    private List<ShipmentEvent> shipmentEventList;
  6. }

ShipmentEvent

  1. @JacksonXmlRootElement(localName = "ShipmentEvent")
  2. public class ShipmentEvent {
  4.     @JacksonXmlElementWrapper(localName = "ShipmentItemList")
  5.     private List<ShipmentItem> shipmentItemList;
  7.     @JacksonXmlProperty(localName = "AmazonOrderId")
  8.     private String amazonOrderId;
  10.     @JacksonXmlProperty(localName = "PostedDate")
  11.     private String postedDate;
  13.     @JacksonXmlProperty(localName = "MarketplaceName")
  14.     private String marketplaceName;
  16.     @JacksonXmlProperty(localName = "SellerOrderId")
  17.     private String sellerOrderId;
  18. }

Unfortunatelly, as a result of the serialization I have:

  1. <ShipmentEventList>
  2.     <ShipmentEventList>
  3.         <ShipmentEvent>
  4.             <AmazonOrderId>A</AmazonOrderId>
  5.             <PostedDate>B</PostedDate>
  6.             <MarketplaceName>C</MarketplaceName>
  7.             <SellerOrderId>D</SellerOrderId>
  8.         </ShipmentEvent>
  9.         <ShipmentEvent>
  10.             <AmazonOrderId>B</AmazonOrderId>
  11.             <PostedDate>C</PostedDate>
  12.             <MarketplaceName>D</MarketplaceName>
  13.             <SellerOrderId>E</SellerOrderId>
  14.         </ShipmentEvent>
  15.     </ShipmentEventList>
  16. </ShipmentEventList>

Could you explain me how does the serialization of collections work in Jackson?

你需要将 useWrapping 标志设置为 false：

  1. class ShipmentEventList {
  3.     @JacksonXmlElementWrapper(useWrapping = false)
  4.     @JacksonXmlProperty(localName = "ShipmentEvent")
  5.     private List<ShipmentEvent> shipmentEventList;
  6. }
英文:

You need to set useWrapping flag to false:

  1. class ShipmentEventList {
  3. 	@JacksonXmlElementWrapper(useWrapping = false)
  4. 	@JacksonXmlProperty(localName = &quot;ShipmentEvent&quot;)
  5. 	private List&lt;ShipmentEvent&gt; shipmentEventList;
  6. }
