public File writeString2File(String Data, String filePath,Logger log)      {      BufferedReader bufferedReader = null;      BufferedWriter bufferedWriter = null;      File distFile=null;     try {      distFile= new File(filePath);              if (!distFile.getParentFile().exists()) distFile.getParentFile().mkdirs();              bufferedReader = new BufferedReader(new StringReader(Data));              bufferedWriter = new BufferedWriter(new FileWriter(distFile));              char buf[] = new char[1024];         //字元緩衝區              int len;              while ((len = bufferedReader.read(buf)) != -1)             {              bufferedWriter.write(buf, 0, len);              }              bufferedWriter.flush();              bufferedReader.close();              bufferedWriter.close();              } catch (Exception e) {              log.info("資訊寫入臨時檔案出錯"+e.toString());                 e.printStackTrace();                 }      return distFile; }
