你试过逐行阅读这个文件吗？
下面是一个如何执行此操作的示例（https://www.digitalocean.com/community/tutorials/java-read-file-line-by-line）：

public class ReadFileLineByLineUsingBufferedReader {

    public static void main(String[] args) {
        BufferedReader reader;

        try {
            reader = new BufferedReader(new FileReader("sample.txt"));
            String line = reader.readLine();

            while (line != null) {
                System.out.println(line);
                // This is where you would split your individual line
                // read next line
                line = reader.readLine();
            }

            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}
