无法查看控制台中打印的阵列的内容 [英] Cannot see the contents of the array printed in console

问题描述

public RMI post(PrintStream stream, Object object)
{
try
{
    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    ObjectOutputStream oos = new ObjectOutputStream(baos);

    //

    oos.writeObject(System.rmi);

    oos.flush();

    oos.close();

    //

    stream.println("Class size: " + baos.toByteArray().length);

    stream.println("Class data: " + baos.toByteArray());

    stream.flush();

    stream.close();

    //
}
catch (Exception e)
{
    e.printStackTrace();
}

return this;

}

这将打印[B @ 12843fce，而不是预期的基础字节码结构.在FileOutputStream中可以找到相同的操作，但在ByteArrayOutputStream中不能找到.我们真的需要这个来工作.您能发现什么地方出了问题或发生了什么事吗?

This prints [B@12843fce instead of the expected underlying bytecode structure. The same operation works find with FileOutputStream but here not with ByteArrayOutputStream. We would really need this to work. Can you spot what's wrong or what's happened?

推荐答案

不要打印对该对象的引用，您需要一种将byte[]转换为String的正确方法，一种常见的方法是Arrays.toString(baos.toByteArray()).

Don't print the reference to the object, you need a proper way to translate the byte[] to a String, and a common way is Arrays.toString(baos.toByteArray()).
