我需要在JAXB XmlElementRef标记生成中提供一些帮助。我有以下课程：
@XmlRootElement(name = "Request")
public class BaseRequest
{
@XmlAttribute(name = "requestid")
private String requestId;
//Getters and Setters
}
@XmlRootElement(name = "ChildRequest")
public class ChildRequest extends BaseRequest
{
private String name = null;
private String id = null;
//Setters and getters
}
@XmlRootElement(name = "PublishRequest")
public class PublishRequest
{
private List<BaseRequest> requests = null;
@XmlElementWrapper(name = "Requests")
@XmlElementRefs({ @XmlElementRef(type = ChildRequest.class) })
public List<BaseRequest> getRequests()
{
return this.requests;
}
}
我希望从这些类中删除XML。
<PublishRequest>
<Requests>
<Request requestid = "">
<ChildRequest>
<name></name>
<id></id>
</ChildRequest>
</Request>
</Requests>
</PublishRequest>
但@XmlElementRef忽略父类属性及其声明的JAXB注释。 任何人都可以帮我生成预期的输出。

您可以使用xjc生成类：
xjc -p <your package> <your XSD>
对于您的方案，以下是XML的xsd：
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="PublishRequest">
<xs:complexType>
<xs:sequence>
<xs:element name="Requests">
<xs:complexType>
<xs:sequence>
<xs:element name="Request">
<xs:complexType>
<xs:sequence>
<xs:element name="ChildRequest">
<xs:complexType>
<xs:sequence>
<xs:element type="xs:string" name="name"/>
<xs:element type="xs:string" name="id"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute type="xs:string" name="requestid"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>

在类中使用@XmlElement注释。更新了以下代码。
@XmlRootElement(name = "Request")
public class BaseRequest
{
@XmlAttribute(name = "requestid")
private String requestId;
//Getters and Setters
@XmlElement(name = "ChildRequest")
ChildRequest childRequest;
}
@XmlRootElement(name = "ChildRequest")
public class ChildRequest extends BaseRequest
{
@XmlElement(name = "name")
private String name = null;
@XmlElement(name = "id")
private String id = null;
//Setters and getters
}
@XmlRootElement(name = "PublishRequest")
public class PublishRequest
{
private List<BaseRequest> requests = null;
@XmlElementWrapper(name = "Requests")
@XmlElementRefs({ @XmlElementRef(type = ChildRequest.class) })
public List<BaseRequest> getRequests()
{
return this.requests;
}
}
