SB的方法对付SB的java API,处理excel，word经常出现类似于： IOException：Unable to read entire block;

java处理excel，word经常出现类似于： IOException：Unable to read entire block; 362 bytes read; expected 512 bytes

 很搞笑。既然expected 512 bytes ，那我就写够512bytes囖。

 ByteArrayOutputStream byteOS = new ByteArrayOutputStream(); 

 FileInputStream fis = new FileInputStream(fileToBeRead);  

byte[] by = new byte[512];  

int t = fis.read(by,0,by.length); 

 while(t>0){   byteOS.write(by, 0, 512);  //这里别写成t，写够512，呵呵，SB的方法对付SB的java API

 t = fis.read(by,0,by.length);  

} 

 byteOS.close();  

InputStream byteIS = new ByteArrayInputStream(byteOS.toByteArray());  

HSSFWorkbook workbook = new HSSFWorkbook(byteIS);
