java读取文件 返回字符串



基础    不多说， 直接贴代码  以后用到直接到这里copy

private String readFileToString(String filepath) throws FileNotFoundException, IOException {
  StringBuilder sb = new StringBuilder();
  String s ="";
  BufferedReader br = new BufferedReader(new FileReader(filepath));

  while( (s = br.readLine()) != null) {
  sb.append(s + "\n");
  }

  br.close();
  String str = sb.toString();
  
  
  return str;
 }
