java - xsd 验证失败

Question

我的 xml 验证失败，原因如下:

Failed to execute goal se.ericsson.jcat.ebs:xml-validation-plugin:1.0.2:validate (default) on project ebs-extensions: Unable to execute mojo: While parsing /home/xchoshu/latestWorkspace/ebs-extensions/src/main/resources/log4j2.xml, at file:/home/xchoshu/latestWorkspace/ebs-extensions/src/main/resources/log4j.xsd, line 18, column 64: src-resolve.4.1: Error resolving component 'ConfigurationType'. It was detected that 'ConfigurationType' has no namespace, but components with no target namespace are not referenceable from schema document 'file:/home/xchoshu/latestWorkspace/ebs-extensions/src/main/resources/log4j.xsd'. If 'ConfigurationType' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'ConfigurationType' has no namespace, then an 'import' without a "namespace" attribute should be added to 'file:/home/xchoshu/latestWorkspace/ebs-extensions/src/main/resources/log4j.xsd'. -> [Help 1]

我的 xds 看起来像:

我的 xml 看起来像:

 <Configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://logging.apache.org/log4j/2.0/config"
    xsi:schemaLocation="http://logging.apache.org/log4j/2.0/config https://ei-switching.rnd.ki.sw.ericsson.se/browser/jcat-bsp/log4j.xsd">

    <Appenders>
        <Console name="JCATDefaultConsoleAppender" target="SYSTEM_OUT"
            follow="true">
            <PatternLayout pattern="%d{default} %m [%t] %l%n%ex{full}" />
        </Console>
    </Appenders>

    <Loggers>
        <Root level="INFO">
            <AppenderRef ref="JCATDefaultConsoleAppender" />
        </Root>
    </Loggers>

任何人都可以帮我纠正 xsd.TIA

问候，舒布汉卡

Answer 1

XSD 缺少命名空间声明xmlns="http://logging.apache.org/log4j/2.0/config"。这使得 XSD 有效。

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
           xmlns="http://logging.apache.org/log4j/2.0/config" 
           targetNamespace="http://logging.apache.org/log4j/2.0/config" 
           elementFormDefault="qualified" 
           attributeFormDefault="unqualified">
    <xs:element name="Configuration" type="ConfigurationType"/>

但是您的 XML 文件有很多问题

您缺少强制元素Properties和ThresholdFilters，并且Appenders应包含至少1个Appender(不是控制台)
