这是 SAP PI 场景。消息在 2 个系统之间交换。源系统：IPOS 目标系统：ECC.. 一旦消息到达 PI 系统，就会生成与 IPOS 对应的 xml。我必须将 IPOS 结构映射到 ECC 结构。这里我使用 DOM 解析器。我使用 main() 进行测试。

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包..

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，我收到错误

com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 2 of 2-byte UTF-8 sequence.

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);
    }

*添加（在上面的代码中注释）以解决问题 - 但它有帮助。我必须添加 UTF-8，但是在哪里添加呢？

这已解决：解决方案是1）在记事本中
打开 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 6）选择编码-->点击保存 xml



filename.xml
UTF-8

您好，您可以在此处找到该问题的参考。问题是 xml 文件声明了与用于保存文件的编码不同的编码。如果文件使用 iso-8859-1 编码并且在文件中它被声明为 UTF-8，您可以使用阅读器读取文件并将编码强制为正确的。该链接显示了执行此操作的 api。
