如何用Java编写UTF-8文件？ [英] How to write a UTF-8 file with Java?

问题描述

我有一些当前的代码，问题是它创建一个1252代码页文件，我想迫使它创建一个UTF-8文件

任何人都可以帮助我与此代码，正如我所说的，目前的工作...但我需要强制保存在utf ..我可以传递一个参数或东西??

这是我有什么，真的赞赏任何帮助

  var out = new java.io.FileWriter（new java.io.File（path ）），
 text = new java.lang.String（src ||）; 
 out.write（text，0，text.length（））; 
 out.flush（）; 
 out.close（）; 
  

解决方案

使用 FileWriter ，创建一个 FileOutputStream 。然后你可以把它封装在一个 OutputStreamWriter 中，它允许你在构造函数中传递一个编码。然后你可以把你的数据写到：

pre $ Output $ Output

I have some current code and the problem is its creating a 1252 codepage file, i want to force it to create a UTF-8 file

Can anyone help me with this code, as i say it currently works... but i need to force the save on utf.. can i pass a parameter or something??

this is what i have, any help really appreciated

var out = new java.io.FileWriter( new java.io.File( path )),
        text = new java.lang.String( src || "" );
    out.write( text, 0, text.length() );
    out.flush();
    out.close();

解决方案

Instead of using FileWriter, create a FileOutputStream. You can then wrap this in an OutputStreamWriter, which allows you to pass an encoding in the constructor. Then you can write your data to that:

OutputStreamWriter writer = new OutputStreamWriter(new FileOutputStream(PROPERTIES_FILE), StandardCharsets.UTF_8)
