## spring boot 项目中redis 序列化异常 ##

当配置好redis配置时候，进行测试redis查询缓存，以下是注解配置下的缓存设置代码：java.lang.IllegalArgumentException: DefaultSerializer requires a Serializable payload but received an object of type

@Cacheable(value="thisredis", key="'device:obj:'+#dvcNo")
        DeviceInfo selectByPrimaryKey(String dvcNo);

关键日志为：

## 详细报错日志： ##

`org.springframework.data.redis.serializer.SerializationException: 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.csii.bean.DeviceInfo] at org.springframework.data.redis.serializer.JdkSerializationRedisSerializer.serialize(JdkSerializationRedisSerializer.java:96) at org.springframework.data.redis.serializer.DefaultRedisElementWriter.write(DefaultRedisElementWriter.java:43) at org.springframework.data.redis.serializer.RedisSerializationContext$SerializationPair.write(RedisSerializationContext.java:241) at org.springframework.data.redis.cache.RedisCache.serializeCacheValue(RedisCache.java:238) at org.springframework.data.redis.cache.RedisCache.put(RedisCache.java:144)`

## 异常原因 ##

redis缓存的类没有实现学序列化接口，导致redis序列化失败。

public class DeviceInfo  { 
        private String dvcNo;
    
        private String dvcName;

改为：

public class DeviceInfo implements Serializable { 
        private String dvcNo;
    
        private String dvcName;

之后经过测试，没有出现以上报错。
