Question

我需要像这样生成我的XML：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<advice_request xmlns="urn:xyz.com:bf:api:core:v1" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<instructions>
    <instruction i:type="advice_instruction_adjust">
        <method>not_set</method>
        <quantity>1</quantity>
        <site_guid>abcd123</site_guid>
    </instruction>
</instructions>
</advice_request>

注意＆＃34;类型＆＃34;属性用＆＃34; i＆＃34;。

限定

我已将xsd定义为：

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns="urn:xyz.com:bf:api:core:v1"
    xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
    targetNamespace="urn:xyz.com:bf:api:core:v1"
    elementFormDefault="qualified" attributeFormDefault="unqualified">  
<xsd:element name="advice_request">
    <xsd:complexType>
        <xsd:sequence>
            <xsd:element name="instructions" type="Instructions" minOccurs="1" maxOccurs="1"/>
        </xsd:sequence>
    </xsd:complexType>
</xsd:element>

<xsd:complexType name="Instructions">
    <xsd:sequence>
        <xsd:element name="instruction" type="Instruction" minOccurs="1" maxOccurs="unbounded"/>
    </xsd:sequence>
</xsd:complexType>

<xsd:complexType name="Instruction">
    <xsd:sequence>
        <xsd:element name="method" type="xsd:string" minOccurs="1" maxOccurs="1"/>
        <xsd:element name="quantity" type="xsd:int" minOccurs="1" maxOccurs="1"/>
        <xsd:element name="site_guid" type="xsd:string" minOccurs="1" maxOccurs="1"/>
    </xsd:sequence>
    <xsd:attribute name="type" id="type" type="xsd:string"/>
</xsd:complexType>
</xsd:schema>

XJC生成以下package-info.java：

@XmlSchema(namespace = "urn:xyz.com:bf:api:core:v1", elementFormDefault = QUALIFIED)

然而，在编组对象时，我总是将XML视为：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<advice_request xmlns="urn:xyz.com:bf:api:core:v1">
<instructions>
    <instruction type="advice_instruction_adjust">
        <method>not_set</method>
        <quantity>1</quantity>
        <site_guid>abcd123</site_guid>
    </instruction>
</instructions>
</advice_request>

如何使用＆＃34; i＆＃34;？任何帮助都非常感激。

我尝试了多种方法，例如导入XMLSchema-instance命名空间，明确地在marshaller上设置SCHEMA_LOCATION（尽管这可能不是我的选项）但仍然没有...

提前致谢！

您应该为complexType使用层次结构。 i:type="advice_instruction_adjust"表示有complextType名为advice_instruction_adjust。

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns="urn:xyz.com:bf:api:core:v1"
    xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
    targetNamespace="urn:xyz.com:bf:api:core:v1"
    elementFormDefault="qualified" attributeFormDefault="qualified">  

    <xsd:element name="advice_instruction_adjust" type="advice_instruction_adjust"/>
    <xsd:complexType name="advice_instruction_adjust">
        <xsd:complexContent>
            <xsd:extension base="Instruction">
            </xsd:extension>
        </xsd:complexContent>
    </xsd:complexType>

    <xsd:element name="Instructions" type="Instructions"/>
    <xsd:complexType name="Instructions">
        <xsd:sequence>
            <xsd:element name="instruction" type="Instruction" minOccurs="1" maxOccurs="unbounded"/>
        </xsd:sequence>
    </xsd:complexType>


    <xsd:complexType name="Instruction" abstract="true">
        <xsd:sequence>
            <xsd:element name="method" type="xsd:string" minOccurs="1" maxOccurs="1"/>
            <xsd:element name="quantity" type="xsd:int" minOccurs="1" maxOccurs="1"/>
            <xsd:element name="site_guid" type="xsd:string" minOccurs="1" maxOccurs="1"/>
        </xsd:sequence>
    </xsd:complexType>
</xsd:schema>

这是XML的一个例子

<?xml version="1.0" encoding="UTF-8"?>
<ns1:Instructions xmlns:ns1="urn:xyz.com:bf:api:core:v1"  xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <ns1:instruction i:type="advice_instruction_adjust">
        <ns1:method />
        <ns1:quantity/>
        <ns1:site_guid/>
    </ns1:instruction>
</ns1:Instructions>

无法使用XJC仅限定xsd属性
