java中的readobect中的EOF异常

Question

当我尝试将byte []数组转换为对象时，我得到了eof异常。两个数组中的最后一个字节相同。

 java.io.EOFException
    at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source)
    at java.io.ObjectInputStream$BlockDataInputStream.readUTFBody(Unknown Source)
    at java.io.ObjectInputStream$BlockDataInputStream.readUTF(Unknown Source)
    at java.io.ObjectInputStream.readUTF(Unknown Source)
    at java.io.ObjectStreamClass.readNonProxy(Unknown Source)
    at java.io.ObjectInputStream.readClassDescriptor(Unknown Source)
    at java.io.ObjectInputStream.readNonProxyDesc(Unknown Source)
    at java.io.ObjectInputStream.readClassDesc(Unknown Source)
    at java.io.ObjectInputStream.readOrdinaryObject(Unknown Source)
    at java.io.ObjectInputStream.readObject0(Unknown Source)
    at java.io.ObjectInputStream.readObject(Unknown Source)

以上是例外。发生这种异常时？请帮忙
