确保XML架构中的唯一属性值

我正在努力确保<context:property-placeholder location="config/application.properties"/> <import resource="jms-listener-container-config.xml"/> <!-- Get Input Messages --> <int-jms:message-driven-channel-adapter id="msgInCDC" channel="toRoute" container="messageListenerContainerCDC" error-channel="errorChannel" acknowledge="transacted"/> <int-jms:message-driven-channel-adapter id="msgInPDC" channel="toRoute" container="messageListenerContainerPDC" error-channel="errorChannel" acknowledge="transacted"/> <!-- Route Messages Depending on Root Element --> <int:channel id="toAircraftAssign"/> <int:channel id="toDiversionChange"/> <int:channel id="toFlightCreate"/> <int:channel id="toFlightPlanRelease"/> <int:channel id="toGateChange"/> <int:channel id="toPositionReport"/> <int:channel id="toScheduleChange"/> <int-xml:xpath-router id="flightUpdateRouter" input-channel="toRoute" default-output-channel="errorChannel" evaluate-as-string="true"> <int-xml:xpath-expression expression="name(/*)"/> <int-xml:mapping value="AircraftAssignment" channel="toAircraftAssign"/> <int-xml:mapping value="DiversionChangesUpdate" channel="toDiversionChange"/> <int-xml:mapping value="CreateFlight" channel="toFlightCreate"/> <int-xml:mapping value="FlightPlanRelease" channel="toFlightPlanRelease"/> <int-xml:mapping value="GateChange" channel="toGateChange"/> <int-xml:mapping value="PositionReportUpdate" channel="toPositionReport"/> <int-xml:mapping value="ScheduleChangesUpdate" channel="toScheduleChange"/> </int-xml:xpath-router> <int-jms:outbound-channel-adapter id="aircraftAssignMsgOut" channel="toAircraftAssign" connection-factory="remoteConnectionFactory" destination="aircraftAssignQueue"/> <int-jms:outbound-channel-adapter id="diversionChangeMsgOut" channel="toDiversionChange" connection-factory="remoteConnectionFactory" destination="diversionChangeQueue"/> <int-jms:outbound-channel-adapter id="flightCreateMsgOut" channel="toFlightCreate" connection-factory="remoteConnectionFactory" destination="flightCreateQueue"/> <int-jms:outbound-channel-adapter id="flightPlanReleaseMsgOut" channel="toFlightPlanRelease" connection-factory="remoteConnectionFactory" destination="flightPlanReleaseQueue"/> <int-jms:outbound-channel-adapter id="gateChangeMsgOut" channel="toGateChange" connection-factory="remoteConnectionFactory" destination="gateChangeQueue"/> <int-jms:outbound-channel-adapter id="positionReportMsgOut" channel="toPositionReport" connection-factory="remoteConnectionFactory" destination="positionReportQueue"/> <int-jms:outbound-channel-adapter id="scheduleChangeMsgOut" channel="toScheduleChange" connection-factory="remoteConnectionFactory" destination="scheduleChangeQueue"/> <!-- Error Handling --> <int-jms:outbound-channel-adapter id="errMsgOut" channel="errorChannel" connection-factory="remoteConnectionFactory" destination="failureQueue"/> <!-- Logger --> <int:wire-tap pattern="to*" order="7" channel="wireTapChannel"/> <int:logging-channel-adapter id="wireTapChannel" level="debug" logger-name="WIRETAP"/> <!-- Logger --> <!-- <int:wire-tap pattern="to*" order="0" channel="loggerChannel"/> --> <!-- <int:logging-channel-adapter id="loggerChannel" level="DEBUG" expression="'YYYY'"/> --> </beans>元素中的属性是唯一的。例如，属性<property_advert>应该是唯一的。我希望下面的XML由于重复的属性而失败。

agent_advert_reference

我的架构如下：

<?xml version="1.0" encoding="UTF-8"?>
<property_adverts xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:schemaLocation="http://www.example.org/XmplifyDerivedSchema.xsd">

    </adverts>
</property_adverts>

我只使用了两天的XML架构，所以请耐心等待我的新问题。提前谢谢。

根本不考虑模式中的唯一约束，因为在复杂类型property_adverts_type中，您使用隐含的复杂类型xs：anyType重新定义名为adverts的元素（因此，它将接受广告元素下的任何内容）。相反，您应该使用ref属性引用广告的全局元素声明。

简而言之，您需要替换

<xs:element name="adverts" minOccurs="1" maxOccurs="1"/>

与

<xs:element ref="adverts" minOccurs="1" maxOccurs="1"/>

我在本地检查过，这样做会在文档上返回一个身份约束错误。
