未找到XPathFactoryImpl错误(使用myBatis)

Question

使用myBatis standAlone(Atlassian jira插件(OSGi)环境)

发生以下错误.

[INFO] [talledLocalContainer] org.apache.ibatis.exceptions.PersistenceException:
[INFO] [talledLocalContainer]     ### Error building SqlSession.
[INFO] [talledLocalContainer]     ### Cause: java.lang.RuntimeException: XPathFactory#newInstance() failed to create an XPathFactory for the default o
bject model: http://java.sun.com/jaxp/xpath/dom with the XPathFactoryConfigurationException: javax.xml.xpath.XPathFactoryConfigurationException: java.
util.ServiceConfigurationError: javax.xml.xpath.XPathFactory: Provider org.apache.xpath.jaxp.XPathFactoryImpl not found
[INFO] [talledLocalContainer] ### Cause: java.lang.RuntimeException: XPathFactory#newInstance() failed to create an XPathFactory for the default object model: http://java.sun.com/jaxp/xpath/dom with the XPathFactoryConfigurationException:javax.xml.xpath.XPathFactoryConfigurationException: java.util.ServiceConfigurationError: javax.xml.xpath.XPathFactory: Provider org.apache.xpath.jaxp.XPathFactoryImpl not found

源代码

static {
    try {
        // set SessionFactory
        if (MyBatisConnectionFactory.sqlSessionFactory == null) {
            MyBatisConnectionFactory.sqlSessionFactory = new SqlSessionFactoryBuilder().build(Resources.getResourceAsStream("/mybatisConfig.xml"));
        }

    } catch (final Exception e) {
        MyBatisConnectionFactory.LOGGER.error(e.getMessage());
    } finally {
    }
}

添加xalan时,会发生以下错误.

Caused by: java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory

Pure Java Application环境中未发生此错误.

我想知道为什么会出现这个错误

请帮我.

谢谢.

我有类似的错误,这个尴尬的东西,在这里记录,修复它为我:

-Djavax.xml.xpath.XPathFactory:http://java.sun.com/jaxp/xpath/dom=com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl

我在macos上使用这个java版本:

java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

来自-Djaxp.debug = 1的stderr帮我找到了这个:

JAXP: Looking up system property 'javax.xml.xpath.XPathFactory:http://java.sun.com/jaxp/xpath/dom'
JAXP: The property is undefined.

所以我给了它正是它所要求的东西,并且它很开心,如此:

JAXP: Looking up system property 'javax.xml.xpath.XPathFactory:http://java.sun.com/jaxp/xpath/dom'
JAXP: The value is 'com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl'
JAXP: createInstance(com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl)
JAXP: loaded com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl from jar:file:/Library/Java/JavaVirtualMachines/jdk1.8.0_92.jdk/Contents/Hom     e/jre/lib/rt.jar!/com/sun/org/apache/xpath/internal/jaxp/XPathFactoryImpl.class
JAXP: factory 'com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl' was found for http://java.sun.com/jaxp/xpath/dom

我很好奇:uri语法,因为以下工作没有:uri.那么为什么XPath需要这个而其他人不需要呢？

-Dcom.sun.org.apache.xml.internal.dtm.DTMManager=com.sun.org.apache.xml.internal.dtm.ref.DTMManagerDefault
-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
