如何验证 mule esb 中的架构？

Question

我需要根据 XSD 架构验证传入的 XML 文件。是否有任何组件可以完成此任务？我怎样才能在 mule esb 中实现这一点？

请建议我对 mule 有点陌生。谢谢..,

你可以使用下面的例子:-

 <mulexml:schema-validation-filter schemaLocations="yourSchema.xsd" returnResult="true" name="Schema_Validation"
        doc:name="Schema Validation" />

并且可以参考您的 .xsd 文件，您的传入 XML 需要根据该文件进行验证。 Mule 有一个验证过滤器，它会为你做验证..

参考：- https://docs.mulesoft.com/mule-user-guide/v/3.7/schema-validation-filter

对于如下代码片段，此处似乎不起作用，但仍收到如下错误。

根据文档使用的代码片段：

 <message-filter throwOnUnaccepted="true" doc:name="Message">
                            <mulexml:schema-validation-filter schemaLocations="GetMasterOrganizationRecordByIDRequest.xsd" returnResult="false"/>
                        </message-filter>

用于验证的架构如下：

    <xs:element name="CustMDGetRequest" type="CustMDGetRequestType"/>

    <xs:complexType name="CustMDGetRequestType">
        <xs:sequence>  
            <xs:element name="CallingSourceSystem" type="xs:string" maxOccurs="1" minOccurs="1"/>
            <xs:element name="SourceSystemId" type="xs:string" maxOccurs="1" minOccurs="1"/>
            <xs:element name="SourceSystemNm" type="xs:string" maxOccurs="1" minOccurs="1"/>
            <xs:element name="IncludeDefaultAttributesForSourceTypes" type="xs:boolean" maxOccurs="1" minOccurs="0"/>
            <xs:element name="SourceTypesToBeIncluded" type="xs:string" maxOccurs="1" minOccurs="0"/>
            <xs:element name="Filters" type="FiltersType" maxOccurs="unbounded" minOccurs="0"/>
            <xs:element name="AsynchronousRequestId" type="xs:string" maxOccurs="1" minOccurs="0"/> 
        </xs:sequence>
    </xs:complexType>

    <xs:complexType name="FiltersType">
        <xs:sequence>
            <xs:element name="Name" type="xs:string" maxOccurs="1" minOccurs="1"/>
            <xs:element name="Values" type="xs:string" maxOccurs="1" minOccurs="1"/>
        </xs:sequence>
    </xs:complexType>

</xs:schema>

收到错误：

Answer 4

使用 .xsd 的模式验证对我不起作用，但使用正则表达式的验证对我有用，如下所示，用于上述问题陈述。

<set-variable variableName="CallingSrcSys" value="#[xpath3('//CallingSourceSystem')]" doc:name="Variable-callingSrcSystem"/>
                <validation:matches-regex value="#[flowVars.CallingSrcSys]" regex="^[a-zA-Z]{0,14}+$" doc:name="Validation-CallingSrcSys"/>
                <set-variable variableName="MandatoryFieldRestrictionLevel" value="#[xpath3('//MandatoryFieldRestrictionLevel')]" doc:name="var-MandatoryFieldRestrictionLevel"/>
                <validation:matches-regex value="#[flowVars.MandatoryFieldRestrictionLevel]"  doc:name="Validation-MandatoryFieldRestrictionLevel" regex="^\s*\d*\s*$"/>
                <set-variable variableName="MinimumSearchScore" value="#[xpath3('//MinimumSearchScore')]" doc:name="var-MinimumSearchScore"/>
                <validation:matches-regex value="#[flowVars.MinimumSearchScore]" regex="^[a-zA-Z]{0,14}+$" doc:name="Validation-MinimumSearchScore"/>
