如何避免关闭传递给我在Reader流中包装的方法的InputStream？

try (InputStream inputStream = new FileInputStream("file.txt")) {
    Reader reader = new InputStreamReader(inputStream);
    // 使用Reader流进行操作
}

public class NonClosingInputStream extends FilterInputStream {
    public NonClosingInputStream(InputStream in) {
        super(in);
    }

    @Override
    public void close() throws IOException {
        // 不关闭InputStream
    }
}

InputStream inputStream = new FileInputStream("file.txt");
NonClosingInputStream nonClosingInputStream = new NonClosingInputStream(inputStream);
Reader reader = new InputStreamReader(nonClosingInputStream);
// 使用Reader流进行操作

InputStream inputStream = new FileInputStream("file.txt");
InputStream closeShieldInputStream = CloseShieldInputStream.wrap(inputStream);
Reader reader = new InputStreamReader(closeShieldInputStream);
// 使用Reader流进行操作

InputStream inputStream = new FileInputStream("file.txt");
Reader reader = new InputStreamReader(inputStream);
try {
    // 使用Reader流进行操作
} finally {
    try {
        reader.close();
    } catch (IOException e) {
        // 处理异常
    }
}
