public void testdeserialize() throws ioexception, classnotfoundexception { bytearrayoutputstream baos = new bytearrayoutputstream(); objectoutputstream oos = new objectoutputstream(baos); biginteger bi = new biginteger(0); oos.writeobject(bi); byte[] str = baos.tobytearray(); objectinputstream ois = new objectinputstream(new bufferedinputstream(new bytearrayinputstream(str))); object obj = ois.readobject(); assertnotnull(obj); assertequals(obj.getclass().getname(),java.math.biginteger); assertequals(((biginteger)obj).intvalue(), 0); }
关键处理
byte[] str = baos.tobytearray();
