JAXB解组 - 意外的元素异常

Question

我尝试解组XML文件中的对象。

我得到这个错误：

javax.xml.bind.UnmarshalException: unexpected element (URI:"", lokal:"ORDER"). Expected elements are <{http://www.opentrans.org/XMLSchema/1.0}ACCOUNT>,<{http://www.opentrans.org/XMLSchema/1.0}ACCOUNTING_INFO>,<{http://www.opentrans.org/XMLSchema/1.0}ADDRESS>,<{http://www.opentrans.org/XMLSchema/1.0}AGREEMENT>,<{http://www.opentrans.org/XMLSchema/1.0}ARTICLE_ID>,<{http://www.opentrans.org/XMLSchema/1.0}ARTICLE_PRICE>,<{http://www.opentrans.org/XMLSchema/1.0}BUYER_AID>,<{http://www.opentrans.org/XMLSchema/1.0}BUYER_PARTY>,<{http://www.opentrans.org/XMLSchema/1.0}CARD>,<{http://www.opentrans.org/XMLSchema/1.0}CASH>,<{http://www.opentrans.org/XMLSchema/1.0}CATALOG_REFERENCE>,<{http://www.opentrans.org/XMLSchema/1.0}CHECK>,<{http://www.opentrans.org/XMLSchema/1.0}CONTACT>,<{http://www.opentrans.org/XMLSchema/1.0}CONTROL_INFO>,<{http://www.opentrans.org/XMLSchema/1.0}COST_CATEGORY_ID>,<{http://www.opentrans.org/XMLSchema/1.0}DEBIT>,<{http://www.opentrans.org/XMLSchema/1.0}DELIVERY_DATE>,<{http://www.opentrans.org/XMLSchema/1.0}DELIVERY_PARTY>,<{http://www.opentrans.org/XMLSchema/1.0}FINAL_DELIVERY_PARTY>,<{http://www.opentrans.org/XMLSchema/1.0}INTERNATIONAL_AID>,<{http://www.opentrans.org/XMLSchema/1.0}INTERNATIONAL_RESTRICTIONS>,<{http://www.opentrans.org/XMLSchema/1.0}INVOICE_PARTY>,<{http://www.opentrans.org/XMLSchema/1.0}MANUFACTURER_INFO>,<{http://www.opentrans.org/XMLSchema/1.0}MIME>,<{http://www.opentrans.org/XMLSchema/1.0}MIME_INFO>,<{http://www.opentrans.org/XMLSchema/1.0}ORDER>,<{http://www.opentrans.org/XMLSchema/1.0}ORDER_HEADER>,<{http://www.opentrans.org/XMLSchema/1.0}ORDER_INFO>,<{http://www.opentrans.org/XMLSchema/1.0}ORDER_ITEM>,<{http://www.opentrans.org/XMLSchema/1.0}ORDER_ITEM_LIST>,<{http://www.opentrans.org/XMLSchema/1.0}ORDER_PARTIES>,<{http://www.opentrans.org/XMLSchema/1.0}ORDER_SUMMARY>,<{http://www.opentrans.org/XMLSchema/1.0}PARTY>,<{http://www.opentrans.org/XMLSchema/1.0}PARTY_ID>,<{http://www.opentrans.org/XMLSchema/1.0}PAYMENT>,<{http://www.opentrans.org/XMLSchema/1.0}PAYMENT_TERM>,<{http://www.opentrans.org/XMLSchema/1.0}PHONE>,<{http://www.opentrans.org/XMLSchema/1.0}PRICE_FLAG>,<{http://www.opentrans.org/XMLSchema/1.0}PUBLIC_KEY>,<{http://www.opentrans.org/XMLSchema/1.0}REMARK>,<{http://www.opentrans.org/XMLSchema/1.0}SHIPMENT_PARTIES>,<{http://www.opentrans.org/XMLSchema/1.0}SOURCING_INFO>,<{http://www.opentrans.org/XMLSchema/1.0}SPECIAL_TREATMENT_CLASS>,<{http://www.opentrans.org/XMLSchema/1.0}SUPPLIER_PARTY>,<{http://www.opentrans.org/XMLSchema/1.0}TRANSPORT>,<{http://www.opentrans.org/XMLSchema/1.0}TRANSPORT_PARTY> 

我unmarshelling过程是这样的：

InputStream is = new FileInputStream(xmlfile); 
JAXBContext jc = JAXBContext.newInstance(ORDER.class); 
Unmarshaller u = jc.createUnmarshaller(); 
ORDER order = (ORDER) u.unmarshal(is); 

我的XML实体样子：

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "", propOrder = { 
    "orderheader", 
    "orderitemlist", 
    "ordersummary" 
}) 
@XmlRootElement(name = "ORDER") 
public class ORDER { 

    @XmlElement(name = "ORDER_HEADER", required = true) 
    protected ORDERHEADER orderheader; 
    @XmlElement(name = "ORDER_ITEM_LIST", required = true) 
    protected ORDERITEMLIST orderitemlist; 
    @XmlElement(name = "ORDER_SUMMARY", required = true) 
    protected ORDERSUMMARY ordersummary; 
    @XmlAttribute(name = "version") 
    protected String version; 
    @XmlAttribute(name = "type") 
    @XmlJavaTypeAdapter(CollapsedStringAdapter.class) 
    protected String type; 

    getters and setters 
} 

我XMLFILE样子：

<?xml version="1.0" encoding="UTF-8" ?> 
<ORDER version="1.0" type="standard"> 
    <ORDER_HEADER> 
     ... 
    </ORDER_HEADER> 
    <ORDER_ITEM_LIST> 
     <ORDER_ITEM> 
      ... 
     </ORDER_ITEM> 
    </ORDER_ITEM_LIST> 
    <ORDER_SUMMARY> 
     ... 
    </ORDER_SUMMARY> 
</ORDER> 

那么，什么是错我的解组过程？ 的XML实体来说与XJC创建。

我想这也与简单的XML文件/对象。这对我来说很好。

Answer 1

错误信息基本上可以归结为：

javax.xml.bind.UnmarshalException: 
    Unexpected element: <{}ORDER> 
    Expected element: <{http://www.opentrans.org/XMLSchema/1.0}ORDER> 

基本上，错误是你的架构是命名空间http://www.opentrans.org/XMLSchema/1.0，但你的文档没有命名空间。

要使其工作，你有3种选择：

1. 添加命名空间XML数据
从XML模式
2. 删除命名空间
3. 解析没有命名空间的支持

我建议＃1，如果可能的话：

<?xml version="1.0" encoding="UTF-8" ?> 
<ORDER version="1.0" type="standard" xmlns="http://www.opentrans.org/XMLSchema/1.0"> 
    <ORDER_HEADER> 
     ... 
    </ORDER_HEADER> 
    <ORDER_ITEM_LIST> 
     <ORDER_ITEM> 
      ... 
     </ORDER_ITEM> 
    </ORDER_ITEM_LIST> 
    <ORDER_SUMMARY> 
     ... 
    </ORDER_SUMMARY> 
</ORDER>
