我们正在解码来自 http://xmlgw.companieshouse.gov.uk/ 的响应.这是发送给编码的文本:
<NameSearch xmlns="http://xmlgw.companieshouse.gov.uk/v1-0/schema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlgw.companieshouse.gov.uk/v1-0/schema http://xmlgw.companieshouse.gov.uk/v1-0/schema/NameSearch.xsd">
<ContinuationKey>...</ContinuationKey>
<RegressionKey>...</RegressionKey>
<SearchRows>20</SearchRows>
<CoSearchItem>
<CompanyName>COMPANY NAME</CompanyName>
<CompanyNumber>23546457</CompanyNumber>
<DataSet>LIVE</DataSet>
<CompanyIndexStatus>DISSOLVED</CompanyIndexStatus>
<CompanyDate></CompanyDate>
</CoSearchItem>
// more CoSearchItem elements
</NameSearch>
CoSearchItem的模型是这样的:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "CoSearchItem", propOrder = {
"companyName",
"companyNumber",
"dataSet",
"companyIndexStatus",
"companyDate",
"searchMatch"
})
public class CoSearchItem {
@XmlElement(name = "CompanyName", required = true)
protected String companyName;
@XmlElement(name = "CompanyNumber", required = true)
protected String companyNumber;
@XmlElement(name = "DataSet", required = true)
protected String dataSet;
@XmlElement(name = "CompanyIndexStatus")
protected String companyIndexStatus;
@XmlElement(name = "CompanyDate")
@XmlSchemaType(name = "date")
protected XMLGregorianCalendar companyDate;
@XmlElement(name = "SearchMatch")
protected String searchMatch;
// getters and setters
}
NameSearch 模型具有以下结构:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "NameSearch", namespace = "http://xmlgw.companieshouse.gov.uk/v1-0/schema", propOrder = {
"continuationKey",
"regressionKey",
"searchRows",
"coSearchItem"
})
@XmlRootElement(name = "NameSearch", namespace = "http://xmlgw.companieshouse.gov.uk/v1-0/schema")
public class NameSearch {
@XmlElement(name = "ContinuationKey", required = true)
protected String continuationKey;
@XmlElement(name = "RegressionKey", required = true)
protected String regressionKey;
@XmlElement(name = "SearchRows", required = true)
protected BigInteger searchRows;
@XmlElement(name = "CoSearchItem")
protected List<CoSearchItem> coSearchItem;
// setters and getters
}
包有这个注解:
@XmlSchema(namespace = "http://xmlgw.companieshouse.gov.uk/v1-0", elementFormDefault = XmlNsForm.QUALIFIED, //
xmlns = {
@XmlNs(prefix = "xsi", namespaceURI = "http://www.w3.org/2001/XMLSchema-instance")
}
)
package uk.gov.companieshouse;
解码是从第一个 Node
完成的,该 Node
从更大的 Document
中提取,在 any
项目列表中。然而,当我们解析 xml 时,CoSearchItem 中的所有字段都设置为 null,无法找出原因。
最佳答案
您需要使用包级 @XmlSchema
注释来指定模型的 namespace 限定。
@XmlSchema(
namespace = "http://xmlgw.companieshouse.gov.uk/v1-0/schema",
elementFormDefault = XmlNsForm.QUALIFIED)
package example;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
这指定您不需要在 NameSearch
类的 @XmlRootElement
和 @XmlType
上指定命名空间 URI。

The unmarshaling is done from the first Node extracted from a larger Document, inside an any list of items.
确保用于创建节点的 DOM 解析器是命名空间感知的。
documentBuilderFactory.setNamespaceAware(true);
