考虑这个 XSD:
<xsd:schema targetNamespace="http://foobar" xmlns:tns="http://foobar"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:complexType name="IdAttribute">
<xsd:attribute name="id" type="xsd:token" />
</xsd:complexType>
<xsd:complexType name="FoobarType">
<xsd:sequence>
<xsd:element name="someIds" type="tns:IdAttribute" maxOccurs="unbounded" />
</xsd:sequence>
</xsd:complexType>
<xsd:element name="Foobar" type="tns:FoobarType" />
</xsd:schema>
这会产生以下生成的 Java 类:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "FoobarType", propOrder = {"someIds"})
public class FoobarType {
@XmlElement(required = true)
protected List<IdAttribute> someIds;
// ...
}
因为IdAttribute
只包含一个 String ( id
),所以我想将这些 String 直接映射到我FoobarType
的字符串中以便于使用。因此我写了一个XmlAdapter
:
public class IdAttributeAdapter extends XmlAdapter<IdAttribute, String> { ... }
我已经手动编辑了生成的类,以XmlAdapter
按预期验证我的作品(确实如此):
@XmlElement(required = true)
@XmlJavaTypeAdapter(IdAttributeAdapter.class)
protected List<String> someIds;
当然,我希望在代码生成期间完成这个小代码更改,所以我添加了以下绑定文件 ( src/main/xjb/bindings.xjb
):
尝试1:
<jaxb:bindings version="2.0" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd">
<jaxb:bindings schemaLocation="../resources/xsd/foobar.xsd">
<jaxb:bindings node="//xsd:complexType[@name='IdAttribute']">
<xjc:javaType
name="java.lang.String"
adapter="org.foobar.IdAttributeAdapter" />
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>
结果
com.sun.istack.SAXParseException2; systemId: file:/C:/dev/foobar/src/main/xjb/bindings.xjb;
lineNumber: 12; columnNumber: 91;
compiler was unable to honor this conversion customization. It is attached to a wrong place, or its inconsistent with other bindings.
尝试2(从这里):
<jaxb:globalBindings xmlns:foo="http://foobar" xsi:schemaLocation="http://foobar ../resources/xsd/foobar.xsd">
<xjc:javaType
name="java.lang.String"
xmlType="foo:IdAttribute"
adapter="org.foobar.IdAttributeAdapter" />
</jaxb:globalBindings>
结果
com.sun.istack.SAXParseException2; systemId: file:/C:/dev/projects/luna/oasch/src/main/xjb/bindings.xjb;
lineNumber: 8; columnNumber: 112;
undefined simple type "{http://foobar}IdAttribute".
我尝试了一些变体,但它们都导致了类似的错误。那么添加XmlApender
使用绑定文件的正确方法是什么?
