BufferedReader读取文件内容中文乱码问题及解决方案

问题代码：使用该代码读取文件内容时，bufferedReader会以系统默认的编码字符集获取文件内容。如果解析设置的编码字符集与系统默认编码字符集不一致，则会出现乱码问题。

File file = new File("D:/1.txt");
BufferedReader br = null;
try { 
	br = new BufferedReader(new FileReader(file));
	String tmpStr = null;
	while ((tmpStr=br.readLine())!=null) {
    	byte[] tmpByte = tmpStr.getBytes(Charset.forName("GBK"));
		String name = new String(tmpByte,0,10,Charset.forName("GBK"));
		String birthday = new String(tmpByte,10, 8,Charset.forName("GBK"));
		String sex = new String(tmpByte,18, 1,Charset.forName("GBK"));
		System.out.println(name+";"+birthday+";"+sex);
	}
} catch (Exception e) {
	e.printStackTrace();
}finally {
	if(br!=null){
		try {
			br.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

修改后的代码：在获取文件流时，设置文件的编码字符集，这样在解析的时候才能正常解析。

    	File file = new File("D:/1.txt");
    	BufferedReader br = null;
    	try {
    		br = new BufferedReader(new InputStreamReader(new FileInputStream(file),Charset.forName("GBK")));
    		String tmpStr = null;
        	while ((tmpStr=br.readLine())!=null) {
        		byte[] tmpByte = tmpStr.getBytes(Charset.forName("GBK"));
    			String name = new String(tmpByte,0,10,Charset.forName("GBK"));
    			String birthday = new String(tmpByte,10, 8,Charset.forName("GBK"));
    			String sex = new String(tmpByte,18, 1,Charset.forName("GBK"));
    			System.out.println(name+";"+birthday+";"+sex);
    		}
		} catch (Exception e) {
			e.printStackTrace();
		}finally {
			if(br!=null){
				try {
					br.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
