java(IO)读写文件乱码转换UTF-8问题
读取文件 String Content = ""; // 文件很长的话建议使用StringBuffer try { FileInputStream fs=new FileInputStream("文件录取"); InputStreamReader isr = new InputStreamReader(fis, "UTF-8"); BufferedReader br = new BufferedReader(isr); String line = null; while ((line = br.readLine()) != null) { Content += line; Content += "\r\n"; // 补上换行符 }catch (Exception e) { e.printStackTrace(); } 写入文件 StringBuffer sb=new StringBuffer();//文件内容 try { FileOutputStream fos=new FileOutputStream("文件路径"); OutputStreamWriter osw=newOutputStreamWriter(fos,"utf-8"); osw.write(sb); osw.close(); }catch (Exception e) { e.printStackTrace(); }
