答案 0 :(得分：4)
Player有Game，Game有Player，Player有Game，Game有Player ... stackoverflow。
更改班级的结构。消除循环引用，或在transient或Player引用上使用Game关键字将其从序列化中排除。
编辑：
如果您不想更改课程结构，例如：每个游戏都引用了播放器，但播放器没有引用其游戏。然后你可以做这样的事情：
private transient Player player;字段，
避免StackOverflowError game.setPlayer(this); 您还需要修复toString()方法。由于Player类的toString()方法调用Game类toString()调用Player类＆{39} toString()
当你StackOverflowError得到这样的事情时。或者不要像这样构建类结构，其中每个Player都有Games，每个Game都有Player。
