Cannot serialize； nested exception is org.springframework.core.serializer

问题描述：

Cannot serialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to serialize object using DefaultSerializer; nested exception is java.lang.IllegalArgumentException: DefaultSerializer requires a Serializable payload but received an object of type [com.itwang.domain.Customer]

---

原因分析：

springboot整合redis时报错，对象不能序列化

---

解决方案：

将对象实现 Serializable 接口

import java.io.Serializable;

public class Customer implements Serializable {
    //***
 }
