Java Nio 读取txt 报错Java.nio.charset.MalformedInputException: Input length = 1

直接用nio读取txt

Path novelPath=Paths.get("C://txt/"+filename); List<String> novellines=Files.readAllLines(novelPath);

结果报错

Exception in thread "main" java.nio.charset.MalformedInputException: Input length = 1

查了下异常说明，是当输入字节序列对于给定 charset 来说是不合法的，或者输入字符序列不是合法的 16 位 Unicode 序列时，抛出此经过检查的异常

想到txt的编码应该是默认的gbk，点开readAllLines方法，显示用的是utf-8读取的

public static List<String> readAllLines(Path path) throws IOException { return readAllLines(path, StandardCharsets.UTF_8); }

改成gbk试试

Path novelPath=Paths.get("C://txt/"+filename); Charset charset= Charset.forName("GBK"); List<String> novellines=Files.readAllLines(novelPath,charset);

ok
