spring-boot - NotSerializableException with redisson-spring-boot-starter

Question

I'm using redisson-spring-boot-starter 3.13.2 and Kotlin for cache but I get the following exception:

java.lang.IllegalArgumentException: java.io.NotSerializableException: com.service.message.State

This is how my config class looks like:

@Configuration
@EnableCaching
class CacheConfig {
    @Bean
    fun cacheManager(client: RedissonClient): CacheManager {
        val config = org.redisson.spring.cache.CacheConfig()
        config.ttl = 10 * 60 * 1000
        return RedissonSpringCacheManager(client, mapOf("State" to config))
    }
}

Type that I'm trying to cache:

data class State(
    val phoneCode: String,
    val phoneNumber: String
)

And this is how I'm trying to cache it:

@CachePut(value = ["State"], key = "#id")
    fun initializeState(phoneAreaCode: String, phoneNumber: String, id: String): State {
        ...
        return State(
            phoneCode = "...",
            phoneNumber = "...",
            ...
        )
    }

Edit: I managed to by pass this error by adding JsonJacksonCodec() to RedissonSpringCacheManager(client, mapOf("State" to config), JsonJacksonCodec()) but now I'm having trouble deserializing:

unable to decode data. channel: [id: 0x81736df6, L:/...], reply: ReplayingDecoderByteBuf(ridx=1704, widx=1704), command: (EVAL), params: [local value = redis.call('hget', KEYS[1], ARGV[2]); if value == false then return nil; end; local t,..., 5, ...

我创建了一个特定的 Kotlin JsonJacksonCodec：

import com.fasterxml.jackson.databind.ObjectMapper
import com.fasterxml.jackson.databind.jsontype.BasicPolymorphicTypeValidator
import org.redisson.codec.JsonJacksonCodec

class JsonJacksonKotlinCodec(objectMapper: ObjectMapper) : JsonJacksonCodec(objectMapper) {

    override fun initTypeInclusion(mapObjectMapper: ObjectMapper) {
        mapObjectMapper.activateDefaultTyping(BasicPolymorphicTypeValidator.builder()
            .allowIfBaseType(Any::class.java)
            .build(), ObjectMapper.DefaultTyping.EVERYTHING)
    }
}

此编解码器覆盖所有类型包含逻辑并包括所有内容的类型。数据类、密封类和一切正常。

要使用它：

val config = Config()
val codec = JsonJacksonKotlinCodec(ObjectMapper())
codec.objectMapper.registerKotlinModule()
config.codec = codec
config.useSingleServer().address = redisConfig.host
redissonClient = Redisson.create(config).reactive()
