ObjectOutputStream 乱码

[doodlesomething]

        FileOutputStream fos = new FileOutputStream(filename);
        ObjectOutputStream oos = new ObjectOutputStream(fos);
        oos.writeObject(new Date());
        

得到


获取编码:

String defaultCharsetName=Charset.defaultCharset().displayName();   
 System.out.println("defaultCharsetName:"+defaultCharsetName);
 

output: defaultCharsetName:UTF-8

Linux 平台(Centos)
vimrc设置:

 if v:lang =~ "utf8$" || v:lang =~ "UTF-8$"
     set fileencodings=gbk,utf-8,chinese,latin-1
     set termencoding=utf-8
     set encoding=utf-8
   endif 

尝试:

 public static void FileWriterTest(String filename) throws IOException {
		String s = "try";
		String s1 = "agin";	
		FileWriter fw = new FileWriter(filename);
		fw.write(s, 0, s.length());
		fw.write(s1,0,s1.length());
		fw.flush();
	}

正常

请教是哪里的问题?Thanks

Object输出的本来就是字节数据，你硬要用记事本打开

明白了,thanks. 基础太差

        FileInputStream ios = new FileInputStream(filename);
        ObjectInputStream iis = new ObjectInputStream(ios);
        Date date = (Date) iis.readObject();
        System.out.println(date);

正常读出
