Java解決BufferedReader读取UTF-8文件中文乱码

1、最近用到了BufferedReader 乱码问题，经过尝试，以下为解决办法原代码为：BufferedRead髫潋啜缅er read = new BufferedReader(new FileReader(new File(filename)));修改后为：因为InputStreamReader和BufferedReader都继承自Reader,而BufferedReader的构造器又是Reader.InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "UTF-8");BufferedReader br= new BufferedReader(isr);以下为全部代码，仅供参考File file = new File(filePath);String isHasFile = "0";StringBuilder sb = new StringBuilder();if(file.exists()){//将文件内容读取出来 InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "UTF-8"); BufferedReader br = new BufferedReader(isr); String s = null; while((s = br.readLine())!=null){ sb.append(s); } br.close();}
