要用到三个包：chardet.jarantlr.jarcpdetector_1.0.7.jar

importinfo.monitorenter.cpdetector.io.CodepageDetectorProxy;
importinfo.monitorenter.cpdetector.io.JChardetFacade;

importjava.io.File;
importjava.nio.charset.Charset;

publicclassCharacterEnding{

publicstaticStringgetFileCharacterEnding(StringfilePath){

Filefile=newFile(filePath);

returngetFileCharacterEnding(file);
}

/**
*Trytogetfilecharacterending.
*</p>
*<strong>Warning:</strong>usecpDetectortodetectfile'sencoding.
*
*@paramfile
*@return
*/
publicstaticStringgetFileCharacterEnding(Filefile){

StringfileCharacterEnding="UTF-8";

CodepageDetectorProxydetector=CodepageDetectorProxy.getInstance();
detector.add(JChardetFacade.getInstance());

Charsetcharset=null;

//Filef=newFile(filePath);

try{
charset=detector.detectCodepage(file.toURL());
}catch(Exceptione){
e.printStackTrace();
}
if(charset!=null){
fileCharacterEnding=charset.name();
}

returnfileCharacterEnding;
}
}
