完美解决java读取大文件内存溢出的问题

Files.readLines(new File(path), Charsets.UTF_8); 
FileUtils.readLines(new File(path));

FileInputStream inputStream = null; 
Scanner sc = null; 
try { 
 inputStream = new FileInputStream(path); 
 sc = new Scanner(inputStream, UTF-8); 
 while (sc.hasNextLine()) {
  String line = sc.nextLine(); 
  // System.out.println(line); 
  } 
}catch(IOException e){
  logger.error(e);
}finally {
  if (inputStream != null) { 
  inputStream.close(); 
  } 
  if (sc != null) {
    sc.close();
   }
}

LineIterator it = FileUtils.lineIterator(theFile, UTF-8); 
try {
 while (it.hasNext()) {
 String line = it.nextLine(); 
 // do something with line 
  } 
} finally {
 LineIterator.closeQuietly(it);
}
