java - ZLIB 输入流意外结束

Question

我正在尝试使用 DeflaterOutputStream 将 JSON 字符串往返转换为字节数组，但下面的代码抛出 java.io.EOFException: Unexpected end of ZLIB input stream。

当您将字符串替换为“Hello world”时，或者如果您从下面的字符串中删除一些字符，它会起作用。

有什么想法吗？

public static void main(String[] args) throws IOException {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    DeflaterOutputStream deflate = new DeflaterOutputStream(bytes, new Deflater(Deflater.BEST_COMPRESSION, true));
    OutputStreamWriter writer = new OutputStreamWriter(deflate);
    writer.write("[1,null,null,\"a\",null,null,null,null,[1,null,null,null,null,null,null,null,null,null,null,null,null,0.0,0.0,null,null]");
    writer.flush();
    writer.close();

    InflaterInputStream inflaterIn = new InflaterInputStream(new ByteArrayInputStream(bytes.toByteArray()), new Inflater(true));
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inflaterIn));
    System.out.println(bufferedReader.readLine());
}

Java 版本 (OSX):

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11A511)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)

Answer 1

我遇到了这个问题，这是因为我没有正确关闭我的输出流。
