Java解決BufferedReader读取UTF-8文件中文乱码

1、最近用到了BufferedReader  匠强海乱码问题，经过尝试，以下为解决办法

原代码为：

BufferedReader 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);   盆凤      String s = null;       往泥  while((s = br.readLine())!=null){                sb.append(s);          }         br.close();}
