本文提供了一个Java方法用于正确读取UTF-8编码的文件，避免中文乱码问题。通过使用InputStreamReader和BufferedReader类，并确保文件编码设置为UTF-8，实现文件内容的正确解析。

Java 读取UTF-8文件中文乱码

InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "UTF-8");

BufferedReader read = new BufferedReader(isr);

例如：

private static String readUTF8File(String filePath) throws IOException {
	InputStreamReader isr = null;
	BufferedReader read = null;
	StringBuffer str = null;
	try {
	    isr = new InputStreamReader(
		    new FileInputStream(new File(filePath)), "UTF-8");
	    read = new BufferedReader(isr);
	    str = new StringBuffer();
	    char[] buff = new char[1024];
	    int byteRead = 0;
	    while ((byteRead = read.read(buff)) != -1) {
		str.append(new String(buff, 0, byteRead));
	    }
	    return str.toString();
	} finally {
	    isr.close();
	    read.close();
	    str = null;
	    isr = null;
	    read = null;
	}
    }

应该没问题，试试吧！
