redis序列化和反序列化

RedisTemplate中需要声明4种serializer，默认为“JdkSerializationRedisSerializer”:

1) keySerializer :对于普通K-V操作时，key采取的序列化策略

2) valueSerializer:value采取的序列化策略

3) hashKeySerializer: 在hash数据结构中，hash-key的序列化策略

4) hashValueSerializer:hash-value的序列化策略

public void setSerializer(RedisTemplate template) {
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
template.setValueSerializer(jackson2JsonRedisSerializer);
template.setKeySerializer(new StringRedisSerializer());
}
