Java USES POI while reading Word document if the document content is empty when abnormal-CodePudding

Exceptions are as follows:
Org, The apache poi. EmptyFileException: The supplied file was empty (zero bytes long)
The at org, apache poi. Util. IOUtils. PeekFirstNBytes (IOUtils. Java: 74)
The at org, apache poi. Util. IOUtils. PeekFirst8Bytes (IOUtils. Java: 57)
The at org, apache poi. Poifs. Filesystem. FileMagic. The valueOf (FileMagic. Java: 135)

Don't know how to avoid the abnormal,
How to determine whether a word document content is empty? Or how to get to the size of a document?

CodePudding user response:

Whether the document content is empty:
The File File=new File (" test. Docx ");
If (the file. The length ()==0) {
System. Out.println (" file is empty!" );
}
In addition to read the Word Document content with Free Spire. Doc for Java is a good method, two lines of code Document Document=new Document (" input. Docx "); String text=document. The getText ();

Upstairs said makes sense

CodePudding user response:

Let the poi generate excel, do not generate its own excel empty file, generate excel is not standard cannot be resolved
