在 jar 文件中引用 XSD 架构

Referencing a XSD schema within jar file(在 jar 文件中引用 XSD 架构)

问题描述

我有两个架构文件，一个是从另一个导入的.在 Eclipse 架构中执行代码时找到但从 jar 架构文件中执行代码时找不到

I have two schema files one is imported from the other. When executing the code in Eclipse schemas are found but when executing the code from jar schema files are not found

这里是代码

SAXParserFactory factory = SAXParserFactory.newInstance();
        factory.setNamespaceAware(true);
        factory.setValidating(false);

        SchemaFactory schemaFactory = SchemaFactory
                .newInstance("http://www.w3.org/2001/XMLSchema");
        try {
            factory.setSchema(schemaFactory.newSchema(new Source[] {
                    new StreamSource(getClass().getResource("Liso.xsd")
                            .getFile()),
                    new StreamSource(getClass().getResource("LisoXml.xsd")
                            .getFile()) }));
                this.saxParser = factory.newSAXParser();
        } catch (SAXException se) {
            System.out.println("SCHEMA : " + se.getMessage()); // problem in the XSD itself
        }

这是我得到的错误

SCHEMA : schema_reference.4: Failed to read schema document 'file:/C:/Tools/lib/LisoTools.jar!/com/xerox/liso/xml/Liso.xsd', because 1) could not find the do
cument; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

谢谢

推荐答案

如果Liso.xsd是在导入LisoXml.xsd，那么定义即可>Liso.xsd 到模式工厂，如下所示.该 API 足够智能，可以加载导入/包含的架构.

If Liso.xsd is importing LisoXml.xsd, then it is just sufficient to define Liso.xsd to the schema factory as shown below. The api is smart enough the load the imported/included schema(s).

SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema")
Schema compiledSchema = schemaFactory.newSchema(getClass().getClassLoader().getResource("Liso.xsd"))

我验证这在 1.5 和 1.6 上都有效.在 1.6 上，您可能会遇到 这个问题如果使用 DOM 就好了.

I verified this worked on both 1.5 and 1.6. On 1.6, you might hit in to this issue as well if using DOM.
