我有简单的xml文件contacts.xml,位于实际文件夹的子文件夹 xml-files 中。
<contacts xsi:noNamespaceSchemaLocation="contacts.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<contact>
<firstname>AAA</firstname>
<lastname>BBB</lastname>
</contact>
</contacts>
架构文件也位于子文件夹 xml-files 。
中解析文件的代码:
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating(true);
SAXParser parser = factory.newSAXParser();
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
SAXReader reader = new SAXReader(parser.getXMLReader());
reader.setValidation(true);
reader.read("xml-files/contacts.xml");
我想使用SAXReader的read方法,它将java.io.Reader作为参数,如下所示
reader.read(new FileReader("xml-files/contacts.xml"));
但我得到例外
org.dom4j.DocumentException:文档第2行出错:cvc-elt.1:无法找到元素'contacts'的声明。嵌套异常:cvc-elt.1:找不到元素'contacts'的声明。
使用自定义实体解析器显示,在第一种情况下,xsd文件是从路径文件中加载的:/// e:/devel/xsd/xml-files/contacts.xsd,在第二种情况下是文件:/// e:/ devel的/ XSD / contacts.xsd。
有没有办法将SAXReader设置为xsd文件所在的文件夹?

未经测试,但从我上面的评论来看,这就是我的想法:
Platform.where(url:urls).eager_load(:campaign_platforms).where.not('campaign_platforms.campaign_id = ?', campaign.id)
答案 1 :(得分:0)
受Java: How to prevent 'systemId' in EntityResolver#resolveEntity(String publicId, String systemId) from being absolutized to current working directory的启发,我使用了自己的EntityResolver2实现
private static class EntityResolver2Impl implements EntityResolver2 {
private File xmlFile;
public EntityResolver2Impl(File xmlFile) {
this.xmlFile = xmlFile;
}
@Override
public InputSource getExternalSubset(String name, String baseURI) throws SAXException, IOException {
return null;
}
@Override
public InputSource resolveEntity(String name, String publicId, String baseURI, String systemId) throws SAXException, IOException {
File entityPath = new File(xmlFile.getParent(), systemId);
return new InputSource(new FileReader(entityPath));
}
@Override
public InputSource resolveEntity(String publicId, String systemId) throws SAXException, IOException {
return null;
}
}
调用代码看起来像这样
File xmlFile = new File("xml-files/contacts.xml");
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating(true);
SAXParser parser = factory.newSAXParser();
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
SAXReader reader = new SAXReader(parser.getXMLReader());
reader.setEntityResolver(new EntityResolver2Impl(xmlFile));
reader.setValidation(true);
reader.read(new FileReader(xmlFile));
此代码还可以处理xsd的路径包含通向父文件夹(../ ..)等的相对路径的情况。
