DefaultSerializer requires a Serializable payload but received an object of type...

1，项目最近改了点东西，今天往redis缓存里存入内容时报错了，如下：

Failed to serialize object using DefaultSerializer; 
nested exception is java.lang.IllegalArgumentException: DefaultSerializer 
requires a Serializable payload but received an object of type [com.xxx.po.UserInfoPo]

2，查找资料才发现上面要缓存的对象没有实现 Serializable接口，果然实现Serializable接口后就不报错了

public class UserInfoPo extends BasePo implements Serializable {
}

 

完
