Question

我正在尝试根据架构验证传入的XML请求。基本上有三种不同的模式CDM_GeneralLedger_v1.0.xsd，GLBookingTypes-v1.0.xsd，CDM_GeneralLedger_v1.0.xsd（CDM_GeneralLedger_v1.0.xsd导入CDM_ISOCurrencyCodes_v1.0.xsd和GLBookingTypes-v1.0.xsd导入CDM_GeneralLedger_v1.0。 xsd）。现在在WSO2 ESB中，我使用的是验证调解器，但是它给了我一个例外情况。

由于机密性，我无法发布我的XSD。但是同样的xsds在TIBCO，Talend等其他工具中运行良好。

Validate介体源代码是：

<sequence xmlns="http://ws.apache.org/ns/synapse" name="validateXml">
   <property xmlns:ns="http://org.apache.synapse/xsd" name="CMMHeader" expression="$body/Message/CMMHeader" scope="default" type="OM"></property>
   <validate xmlns:ns="http://org.apache.synapse/xsd" xmlns:tns="http://com.glbooking/v1/data" source="//tns:GLBookingMessage">
      <schema key="conf:/XSD/CDM_GeneralLedger_v1.0.xsd"></schema>
      <schema key="conf:/XSD/GLBookingTypes-v1.0.xsd"></schema>
      <schema key="conf:/XSD/CDM_ISOCurrencyCodes_v1.0.xsd"></schema>
      <on-fail>
         <makefault version="pox">
            <reason value="XML Request is invalid. Error while validating "></reason>
            <detail>Invalid XML Request</detail>
         </makefault>
         <log level="full" category="ERROR"></log>
         <payloadFactory media-type="xml">

                  <ErrorMessage>Error while validating XML</ErrorMessage>

            </args>
         </payloadFactory>
         <send>
            <endpoint key="conf:/GLBookingErrorQueue_EPLOCAL"></endpoint>
         </send>

   </validate>

应定义主模式外部的外部模式文件使用资源元素

<validate>
    <schema key="conf:/XSD/Employee.xsd"/>
    <resource location="XSD/Address.xsd" key="conf:XSD/Address.xsd"/>
    <on-fail>
        <makefault version="soap11">
            <code xmlns:soap11Env="http://schemas.xmlsoap.org/soap/envelope/" value="soap11Env:Client"/>
            <reason value="Invalid xml"/>
            <role/>
        </makefault>
    </on-fail>
</validate>

location属性的值（上例中的XSD / Address.xsd）应该是schemaLocation属性的值

以下是示例模式文件

的employee.xsd

<xs:schema elementFormDefault="qualified" targetNamespace="http://schemas.srd.com/Employee" xmlns="http://schemas.srd.com/Employee" xmlns:addr="http://schemas.srd.com/Address"  xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:import namespace="http://schemas.srd.com/Address" schemaLocation="XSD/Address.xsd"/>
    <xs:element name="Employee">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" name="ename" type="xs:string"/>
                <xs:element minOccurs="0" name="deptno" type="xs:string"/>
                <xs:element minOccurs="0" name="hiredate" type="xs:string"/>
                <xs:element minOccurs="0" name="job" type="xs:string"/>
                <xs:element minOccurs="0" name="mgr" type="xs:string"/>
                <xs:element minOccurs="0" name="sal" type="xs:decimal"/>
                <xs:element minOccurs="0" name="comm" type="xs:decimal"/>
                <xs:element ref="addr:Address"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

Address.xsd

<xs:schema elementFormDefault="qualified" targetNamespace="http://schemas.srd.com/Address" xmlns="http://schemas.srd.com/Address" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="Address">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" name="city" type="xs:string"/>
                <xs:element minOccurs="0" name="state" type="xs:string"/>
                <xs:element minOccurs="0" name="country" type="xs:string"/>
                <xs:element minOccurs="0" name="postalCode" type="xs:string"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

针对在WSO2 ESB中导入另一个xsd的Schema验证XML
