java - JaxB 属性值已定义。使用 to resolve this conflict

Question

我正在使用以下 xsd 架构文件来生成 java 类

<xsd:complexType name="Instruction">
<xsd:choice>
    <xsd:sequence>
        <xsd:element name="InstructionIndicator" type="InstructionIndicator">
            <xsd:annotation>
                <xsd:documentation>some text</xsd:documentation>
            </xsd:annotation>
        </xsd:element>
        <xsd:sequence minOccurs="0" maxOccurs="49">
            <xsd:element name="MultipleTimingModifier" type="ANDOR"
                minOccurs="0">
                <xsd:annotation>
                    <xsd:documentation>some text</xsd:documentation>
                </xsd:annotation>
            </xsd:element>
            <xsd:element name="TimingAndDuration" type="TimingAndDuration" />
        </xsd:sequence>
    </xsd:sequence>
    <xsd:sequence>
        <xsd:choice>
            <xsd:element name="AdministrationIndicator" type="AdministrationIndicator">
                <xsd:annotation>
                    <xsd:documentation>some text</xsd:documentation>
                </xsd:annotation>
            </xsd:element>
            <xsd:sequence>
                <xsd:element name="DoseAdministration" type="DoseAdministration" />
                <xsd:element name="TimingAndDuration" type="TimingAndDuration">
                    <xsd:annotation>
                        <xsd:documentation>some text</xsd:documentation>
                    </xsd:annotation>
                </xsd:element>
                <xsd:sequence minOccurs="0" maxOccurs="49">
                    <xsd:element name="MultipleTimingModifier" type="ANDOR"
                        minOccurs="0">
                        <xsd:annotation>
                            <xsd:documentation>some text</xsd:documentation>
                        </xsd:annotation>
                    </xsd:element>
                    <xsd:element name="TimingAndDuration" type="TimingAndDuration" />
                </xsd:sequence>
            </xsd:sequence>
        </xsd:choice>
        <xsd:sequence minOccurs="0">
            <xsd:element name="IndicationForUse" type="Indication"
                maxOccurs="50">
                <xsd:annotation>
                    <xsd:documentation>some text</xsd:documentation>
                </xsd:annotation>
            </xsd:element>
            <xsd:element name="IndicationClarifyingFreeText" type="an1..255"
                minOccurs="0" />
        </xsd:sequence>
        <xsd:element name="MaximumDoseRestriction" type="MaximumDoseRestriction"
            minOccurs="0" maxOccurs="50">
            <xsd:annotation>
                <xsd:documentation>some text</xsd:documentation>
            </xsd:annotation>
        </xsd:element>
    </xsd:sequence>
</xsd:choice>

但是处理这个会导致错误

Property "MultipleTimingModifierAndTimingAndDuration" is already defined. Use <jaxb:property> to resolve this conflict.

为了解决这个问题，我编写了一个包含以下内容的绑定(bind)文件

<jaxb:bindings xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
jaxb:extensionBindingPrefixes="xjc" version="2.0">

<jaxb:bindings schemaLocation="structures.xsd"
    node="//xs:complexType[@name='Instruction']/xs:choice[1]
    /xs:sequence[1]/xs:sequence/xs:element[@name='MultipleTimingModifier']">
    <jaxb:property name="MultipleTimingModifier1" />
</jaxb:bindings>

<jaxb:bindings schemaLocation="structures.xsd"
    node="//xs:complexType[@name='Instruction']/xs:choice
    /xs:sequence[1]/xs:sequence/xs:element[@name='TimingAndDuration']">
    <jaxb:property name="TimingAndDuration1" />
</jaxb:bindings>

在 elcipse 中生成 Jaxb 类时添加此绑定(bind)文件后，会产生以下错误

compiler was unable to honor this property customization. It is attached to a wrong place, or its inconsistent with other bindings.

如果从目标序列节点中删除 maxoccurrs="49"约束，类将成功生成

注意:

• 架构是 5 个不同文件的组合，超过 2000 行
• 这里仅分享产生错误的部分

使用以下绑定(bind)代码我已经解决了我的问题

<jaxb:bindings
     schemaLocation="structures.xsd"
     node="//xs:complexType[@name='Instruction']/xs:choice/xs:sequence[1]/xs:sequence[1]">
     <jaxb:property name="seq1"/>
</jaxb:bindings>
