使用FileOutputStream序列化可以直接向文件写入文本内容,代码如下:
File file = new File("文件路径+文件名") FileOutputStream outStream = new
FileOutputStream(file); outStream.write(str.getBytes()); outStream.close();
但这里的字符串如果包含中文,就会出现乱码,这是因为FileOutputStream是字节流,将文本按字节写入文件,而一个汉字是两个字节
,无法一次写入,就会出现乱码,解决方法是使用OutputStreamWriter将字节流转换为字符流写入,同时指定utf-8编码。代码如下:
File file = new File("文件路径+文件名") OutputStreamWriter oStreamWriter = new
OutputStreamWriter(new FileOutputStream(file), "utf-8"); //追加内容到文件中
oStreamWriter.append(str); //写入文件到文件中
//oStreamWriter.write(sb.toString().replace("\n","\r\n")) oStreamWriter.close();
