无法在 Spring 反应性 Redis 缓存中存储 Boolean

Question

" java.lang.IllegalStateException: Cannot serialize value of type class java.lang.Boolean without a serializer

我在存储 Boolean 时遇到此异常。

我的 redis 配置：

ReactiveRedisTemplate<String, Object> reactiveRedisTemplateGeneric(ReactiveRedisConnectionFactory reactiveRedisConnectionFactory) {
    GenericJackson2JsonRedisSerializer valueSerializer = new GenericJackson2JsonRedisSerializer();
    RedisSerializationContext.RedisSerializationContextBuilder<String, Object> builder =
            RedisSerializationContext.newSerializationContext(new StringRedisSerializer());
    RedisSerializationContext<String, Object> context = builder.value(valueSerializer).build();
    return new ReactiveRedisTemplate<>(reactiveRedisConnectionFactory, context);
}

在构建上下文时，我们还需要在 hashValue 中设置序列化程序。

RedisSerializationContext<String, Object> context = builder.value(valueSerializer).hashValue(valueSerializer).build();
