【问题描述】:
我正在尝试创建一个 RedisTemplate bean,它将具有更新的值序列化程序,以在 redis 中序列化 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序列化器来序列化带有Cacheable注解的方法返回的对象。尽管有这种配置,spring 似乎使用了默认的 Java 序列化程序,因为这个异常证实了这一事实。

我是否遗漏了 spring 无法确定使用什么 RedisTemplate 的任何配置或内容?
