RedisTemplate 序列化(配置类)

@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
//创建redistemplate对象
        RedisTemplate<String, Object> objectObjectRedisTemplate = new RedisTemplate<>();
//        设置连接工厂
        objectObjectRedisTemplate.setConnectionFactory(redisConnectionFactory);
//        创建json序列化工具
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
//        设置key的序列化
        objectObjectRedisTemplate.setKeySerializer(RedisSerializer.string());
        objectObjectRedisTemplate.setHashKeySerializer(RedisSerializer.string());
//        设置value的序列化
        objectObjectRedisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);
        objectObjectRedisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer);
//        返回
        return objectObjectRedisTemplate;
    }
}
