Question

我在我的代码中使用了DocumentBuilder类的parse()方法。

文件doc = dBuilder.parse（bis）;

在上面一行，它抛出异常：

com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 3 of 3-byte UTF-8 sequence.

如果有人知道根本原因和解决方案，请建议。

提前致谢。

对我来说，更改解析功能是：从文件XML到InputSource（将字符集更改为UTF）

 InputStream inputStream= new FileInputStream(file); 
 Reader reader = new InputStreamReader(inputStream,"UTF-8");        
 InputSource is = new InputSource(reader); 
 is.setEncoding("UTF-8");
 doc = dBuilder.parse(is);

怎么解决？ com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException：3字节UTF-8序列的无效字节3
