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);  }  }}
