java - 声明导致 ObjectFactory 中的冲突

Question

我有两个 xsd 导入到主 xsd 中。两者具有相同的元素，但命名空间不同。因此，我为第二个 xsd(B.xsd) 创建了自定义绑定(bind)。我仍然收到“两个声明导致 ObjectFactory 类中发生冲突”。据我了解，自定义绑定(bind)实际上会为默认 XML 名称到 Java 标识符映射无法自动处理的情况提供有意义的自定义名称。因此，将避免冲突。

A.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="urn:abc:def:ghi" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:element name="lotNumber" type="xs:string"/>
    <xs:element name="itemExpirationDate" type="xs:date" />

</xs:schema>

B.xsd

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
     xmlns="http://abc.def.org/kj/ns"
     targetNamespace="http://abc.def.org/kj/ns"
     elementFormDefault="qualified"
     attributeFormDefault="unqualified">
    <xs:element name="ilmd">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="lotNumber" minOccurs="0"/>
                <xs:element ref="itemExpirationDate" minOccurs="0"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:element name="lotNumber" type="xs:string"/>
    <xs:element name="itemExpirationDate" type="xs:string"/>
</xs:schema>

绑定(bind).xml

<jaxb:bindings
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"

        </jaxb:bindings>

如果元素内部包含complextype，则应该为complextype添加name属性

<xs:element name="ilmd">
        <xs:complexType **name="ilmdArray"**>
            <xs:sequence>
                <xs:element ref="lotNumber" minOccurs="0"/>
                <xs:element ref="itemExpirationDate" minOccurs="0"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
