从jar加载xslt文件加载jar本身，而不是xslt

Question

我有一个xslt文件在classpath里面的jar文件。我曾尝试使用InputStream加载xslt文件。一些如何在调试后，InputStream代替xslt文件包含jar文件。

String xslPath = "/com/japi/application/templates/foo.xslt"; 
InputStream is = getClass().getResourceAsStream(xslPath); 
... 
Source xslt = new StreamSource(is); 
trans = factory.newTransformer(xsltSource); //Fatal error. Error parsing XSLT {0} 

我已经仔细检查xslt文件的路径是否正确，物理文件是否包含在jar中。任何想法的人？

Answer 1

InputStream中包含的jar文件，而不是 XSLT文件

是什么让你这么说？您是否尝试将文本内容InputStream打印出来？在创建InputStream in并使用它之间，你是否正在做其他事情（......部分）？

如果提供给getResourceAsStream点到XSLT，如果is路径是呼叫后不null，is应该包含代表XSLT资源InputStream。如何粘贴整个堆栈跟踪？

Answer 2

试试这个

String pathWithinJar = "com/example/xslt/dummy.xslt"; 
InputStream is = java.lang.ClassLoader.getSystemResourceAsStream(pathWithinJar); 

那你能给我们IOUtils（阿帕奇）或建议here一个InputStream的转换为字符串或只使用接受输入的javax.xml ... StreamSource的构造函数流。

public static void transform(InputStream xslFileStream, File xmlSource, File xmlResult) 
     throws TransformerException, IOException { 

    // unknown if the factory is thread safe, always create new instance 
    TransformerFactory factory = TransformerFactory.newInstance(); 
    StreamSource xslStreamSource = new StreamSource(xslFileStream); 
    Transformer transformer = factory.newTransformer(xslStreamSource); 

    StreamSource sourceDocument = new StreamSource(xmlSource); 
    StreamResult resultDocument = new StreamResult(xmlResult); 
    transformer.transform(sourceDocument, resultDocument); 

    resultDocument.getOutputStream().flush(); 
    resultDocument.getOutputStream().close(); 
    }

创建自定义解析从类路径来解决 组到Transfromer 测试，我在类路径Eclipse项目设定一个jar文件

所有的代码是在这里下面 -----运行示例------------- '

public class RunTransform { 

    public static void main(String[] args) { 

     // SimpleTransform.transform("xsl/SentAdapter.xsl", "C:/Amin/AllWorkspaces/ProtoTypes/XsltDemo/xml/acc.xml"); 

     SimpleTransform.transform("xslt/ibanvalidation/accuity-ibanvalidationresponse.xsl", "C:/Amin/AllWorkspaces/ProtoTypes/XsltDemo/xml/acc.xml"); 
    } 

} 

-----------Sample transfomring example ----------------

package com; 

import java.io.File; 
import java.io.FileOutputStream; 


import javax.xml.transform.Templates; 
import javax.xml.transform.Transformer; 
import javax.xml.transform.TransformerFactory; 
import javax.xml.transform.URIResolver; 
import javax.xml.transform.stream.StreamResult; 
import javax.xml.transform.stream.StreamSource; 


public class SimpleTransform { 

    public static void transform(String xslName,String xmlName) { 
     try { 
      ResourceResolver resloader = new ResourceResolver(); 
       TransformerFactory tFactory = TransformerFactory.newInstance(); 
       tFactory.setURIResolver(resloader); 

       StreamSource xsltSRC = new StreamSource(resloader.resolve(xslName)); 

       Transformer transformer = tFactory.newTransformer(xsltSRC); 

       StreamSource xmlSSRC = new StreamSource(xmlName); 
       System.out.println("Streamm sources created ....."); 

       System.out.println("XSLT SET ...."); 
       transformer.transform(xmlSSRC, new StreamResult(new FileOutputStream(new File("C:/Amin/AllWorkspaces/ProtoTypes/XsltDemo/xml/result.xml")))); 
       System.out.println("Finished transofrmation .........."); 
       System.out.println("************* The result is out in respoinse *************"); 


      } catch (Throwable t) { 
         t.printStackTrace(); 
      } 

    } 

}
