org.springframework.data.redis.serializer.SerializationException: Cannot serialize（解决redis存入对象序列化）

org.springframework.data.redis.serializer.SerializationException: Cannot deserialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to deserialize payload. Is the byte array a result of corresponding serialization for DefaultDeserializer?; nested exception is java.io.InvalidClassException: com.xs.entity.XXX; class invalid for deserializationat org.springframework.data.redis.serializer.JdkSerializationRedisSerializer.deserialize

在调用service 实现类时报出以上错误，原因是因为 spring会先将对象序列化，再存入redis进行缓存，而entity没有实现序列化接口，因此序列化出错，需要在对应的实体类中添加序列化即可（implements Serializable），如下：

@Override@Cacheable(value = "student")public Student getStudentById(int id) {return studentMapper.getStudentById(id);}

public class Student implements Serializable{privateint id;private String name;private String fullname;}
