SAP PI映射中2字节UTF-8序列的无效字节2 [英] Invalid byte 2 of 2-byte UTF-8 sequence in SAP PI mapping

问题描述

这是SAP PI业务情景.该消息在2个系统之间交换.源系统:IPOS目标系统:ECC ..消息到达PI系统后，将生成一个与IPOS相对应的xml.我必须将IPOS结构映射到ECC结构.在这里，我正在使用DOM解析器..我正在使用main()进行测试.

This is SAP PI scenario. The message is exchanged between 2 systems. Source System: IPOS Target system: ECC.. Once the message reaches PI system an xml corresponding to IPOS is generated. I have to map the IPOS structure to ECC structure. Here I am using DOM parser.. I am using main() for testing purpose.

public static void main (String str[]) throws FileNotFoundException, StreamTransformationException { 

    ZcreateHomeDelivery obj = new ZcreateHomeDelivery();

    try { 


    InputStream inputStream  = new FileInputStream("C:/Users/XYZ/workspace/input.xml");

    FileOutputStream newOut = new FileOutputStream("C:/Users/XYZ/workspace/output.xml");  
    obj.execute(inputStream, newOut);
    }catch (Exception e ) { 
        e.printStackTrace();
    }}

我已经导入了所有必需的软件包.

I have imported all the required packages..

import com.sap.aii.mapping.api.AbstractTrace;
import com.sap.aii.mapping.api.StreamTransformation;

我面临的问题是当我执行代码时，出现错误信息

The problem I am facing is when I execute the code, I am getting error as

我尝试过的解决方案是

try
    {
        TransformerFactory tFactory = TransformerFactory.newInstance();
        Transformer transformer = tFactory.newTransformer();
        transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");// added
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        DOMSource source = new DOMSource(outdoc);
        StreamResult result = new StreamResult(outputStream);
        transformer.transform(source, result);
    } catch (Exception e) {
        e.printStackTrace();
        throw new StreamTransformationException("Mapping failed:Check input file", e);
    }

*已添加(在上面的代码中作了注释)来解决此问题-但它有帮助.我必须添加UTF-8，但是在哪里添加呢?

*added(Commented in the above code) to resolve the issue- But it dint help. I have to add UTF-8 , But where to add it ?

这已解决:解决方案是
1)在记事本中打开xml
2)确保文档的开头和结尾没有多余的空间.
3)选择文件->另存为
4)选择保存类型->所有文件
5)输入文件名称为filename.xml
6)选择编码"-UTF-8->单击保存"

This is resolved : solution is
1)Open the xml in notepad
2)Make sure you dont have extra space at the beginning and end of the document.
3)Select File -> Save As
4)select save as type -> All files
5)Enter file name as filename.xml
6)select Encoding - UTF-8-> Click Save

推荐答案

您可以找到

Hi you can find here a reference to the problem. The problem is that the xml file declares a different encoding from the one used for saving the file. If the files are encoded using iso-8859-1 and in the file it's declared as UTF-8 you can read the file using a reader and force the encoding to the correct one. the link shows the api for doing this.
