为什么我不能使用外部映射将“type”属性覆盖为非瞬态?如下所示?当我序列化时,我没有看到“type”元素。
public class PhoneNumber
{
private String type;
@XmlTransient
public String getType()
{
return type;
}
//other properties
}
我使用“xml-attribute”指定“type”,希望这将优先于注释,但它不起作用。
<java-type name="PhoneNumber">
<java-attributes>
<xml-attribute java-attribute="type" />
<xml-value java-attribute="number" />
</java-attributes>
</java-type>

您似乎遇到了错误。您可以使用以下链接跟踪我们在此问题上的进展情况:
解决方法强>
您可以指定字段访问权应用于PhoneNumber
类。
<java-type name="PhoneNumber" xml-accessor-type="FIELD">
<java-attributes>
<xml-attribute java-attribute="type" />
<xml-value java-attribute="number"/>
</java-attributes>
</java-type>
