的SAXParseException; src-resolve:无法将名称"..."解析为(n)'类型定义'组件

Question

我正在尝试进行模式验证,目前使用的是javax.xml.validation.SchemaFactory.不幸的是,当我调用该newSchema(Source schema)函数时,我收到以下错误:

Caused by: org.xml.sax.SAXParseException; systemId: file:/C:/Users/C42056/Documents/workspace-sts-3.2.0.RELEASE/cec-sample-ws-integration-2-war/target/classes/WEB-INF/schemas/xsd/individual/PrivateComponentTypes_4_0.xsd; lineNumber: 33; columnNumber: 88; src-resolve: Cannot resolve the name 'utility:ObjectStatusDateType' to a(n) 'type definition' component.

该utility:ObjectStatusDateType元素用于我传递给newSchema(Source schema)函数的.xsd文件中.我ObjectStatusDateType从另一个.xsd文件导入 - 我已经检查了文件路径.该utility命名空间还正确声明.

这是我传递给函数的模式的片段(LocateCoverageIndexesByIdentifier_3_0.xsd):

<xs:import namespace="http://www.sei.com/utility/1/" schemaLocation="../../utility/InvocationOutcome_1_0.xsd"/>
<xs:import namespace="http://www.sei.com/utility/1/" schemaLocation="../../utility/ObjectHistory_1_0.xsd"/>
<xs:import namespace="http://www.sei.com/individual/component/4/" schemaLocation="../PrivateComponentTypes_4_0.xsd"/>
<xs:import namespace="http://www.sei.com/individual/shared/5/" schemaLocation="../IndividualTypes_5_0.xsd"/>
.
. <!-- Some more stuff -->
.
<xs:element name="coveragePeriod" 
            type="utility:ObjectStatusDateType" 
            minOccurs="0"/>

这是来自ObjectHistory_1_0.xsd:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
           xmlns:tns="http://www.sei.com/utility/1/" 
           targetNamespace="http://www.sei.com/utility/1/" 
           elementFormDefault="qualified" 
           attributeFormDefault="unqualified" 
           version="1.0">
.
. <!-- Some more stuff -->
.
  <xs:complexType name="ObjectStatusDateType">
    <xs:sequence>
      <xs:element name="effectiveDate" type="xs:date"/>
      <xs:element name="cancelDate" type="xs:date" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>

最后,豆子

<bean id="locateClaimValidator" 
      class="com.sei.ec.xml.validation.SimpleXmlValidator">

    <value>classpath:WEB-INF/schemas/xsd/individual/ci/LocateCoverageIndexesByIdentifier_3_0.xsd
    </value>
  </constructor-arg>
</bean>

以前有人遇到过这类问题吗？

Answer 1

我以前遇到过这个问题.所有在Eclipse中验证的东西,但在运行时破坏了.您的任何模式是否将多个模式导入同一名称空间？

这样的东西不起作用,但将由Eclipse验证:

<import namespace="http://www.whatever.gov" location="../wherever" />
<import namespace="http://www.whatever.gov" location="../folder/superawesomeschema.xsd" />

Answer 2

很多人以前遇到过这类问题.无论出于何种原因,只要您的验证器没有加载您希望它加载的架构文档(并认为它正在加载),它就会出现.

要确认诊断:尝试在ObjectHistory_1_0.xsd中引入错误(例如,格式错误),并查看系统是否抱怨.

Answer 3

使用 Xerces 可以通过将特性设置http://apache.org/xml/features/honour-all-schemaLocations为 true来解决这个问题 。

该功能http://apache.org/xml/features/honour-all-schemaLocations仅在 Xerces 2.7.0 中可用。当前版本的 Java 5.0 和 6.0 内置了 Xerces 2.6.2。因此，必须使用较新的 Xerces 库才能使其正常工作，即。复制xml-apis.jar和xercesImpl.jar到<jdk-home>/jre/lib/endorsed和创建jaxp.properties文件<jdk-home>/jre包含行
