fastjson序列化ByteBuffer的问题

[zplinuxlover]

1. 我的测试代码是

  @Test
    public void test() {
        ByteBuffer buff = ByteBuffer.allocate(32);
        buff.putInt(100);
        buff.flip();
        Map<String, Object> map = new HashMap<>();
        map.put("binary", buff);
        String result = JSON.toJSONString(buff);
        System.out.println(result);
    }

我使用的fastjson的代码是1.2.56版本
出现的异常是
