Java使用utf8格式保存文本文件的方法

FileOutputStream fos = null;
OutputStreamWriter writer = null;
try {
  File file = new File(filepath);
  fos = new FileOutputStream(file);
  writer = new OutputStreamWriter(fos,"utf-8");
  writer.write(makeLanguageRes(resource));
} catch (Exception e) {
  CheckXmlUtil.addErrorMsg(CheckXmlUtil.TEXT_FOMART_ERROR,
   CheckXmlUtil.SAVE_XML_FIALL, e);
  return null;
} finally {
  try {
  if(fos != null){
   fos.close();
  }
} catch (IOException e1) {
  CheckXmlUtil.addErrorMsg(CheckXmlUtil.TEXT_FOMART_ERROR,
   CheckXmlUtil.SAVE_XML_FIALL, e1);
}
if (writer != null) {
  try {
   writer.close();
  } catch (IOException e) {
   CheckXmlUtil.addErrorMsg(CheckXmlUtil.TEXT_FOMART_ERROR,
    CheckXmlUtil.SAVE_XML_FIALL, e);
  }
  }
}
