我正在尝试创建一个RedisTemplate
bean,它将具有更新的值序列化程序,以以redis格式序列化一个JSON
格式的对象。
@Configuration
class RedisConfig {
@Bean(name = ["redisTemplate"])
@Primary
fun template(factory: RedisConnectionFactory): RedisTemplate<Any, Any> {
val template = RedisTemplate<Any, Any>()
template.connectionFactory = factory
template.valueSerializer = Jackson2JsonRedisSerializer(Object::class.java)
template.afterPropertiesSet()
return template
}
}
根据我的理解,spring应该使用JSON序列化程序来序列化标记为Cacheable
注释的方法返回的对象。尽管有这种配置,spring似乎在使用默认的Java序列化程序,因为此异常证实了这一事实。

我是否遗漏了任何配置或者spring无法确定使用什么RedisTemplate
的东西?

你可能已经解决了它的同时,但为进一步的答案寻求者。
根据春季数据红皮书参考文献
默认情况下,RedisCache和RedisTemplate配置为使用本机序列化。
从堆栈跟踪中,我可以看到您实际上是在使用Redis进行缓存,因此您需要配置RedisCache
而不是RedisTemplate
。RedisCache
没有拿起您的@Bean
,因为它没有在内部使用RedisTemplate
。
例如,如何在Java中这样做:
@EnableCaching
@Configuration
public class CacheConfig {
@Bean
@Primary
public RedisCacheConfiguration defaultCacheConfig(ObjectMapper objectMapper) {
return RedisCacheConfiguration.defaultCacheConfig()
.serializeKeysWith(SerializationPair.fromSerializer(new StringRedisSerializer()))
.serializeValuesWith(SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer(objectMapper)));
}
}
