RedisConfig通用配置

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory)
    throws UnknownHostException {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
       redisTemplate.setConnectionFactory(factory);

       //Json序列化配置
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        //指定要序列化的域，field,get和set，以及修饰符范围，ANY是都有，包括private和public
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        //指定序列化输入的类型，类必须是非final修饰的，final修饰的类，比如String，Integer等会抛出异常
        om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);

        //配置具体的序列化方式
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        //key采用String的序列化方式
        redisTemplate.setKeySerializer(stringRedisSerializer);

        //hash的key也采用String的序列化方式
        redisTemplate.setHashKeySerializer(stringRedisSerializer);

        //value序列化采用jackson
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();

        return  redisTemplate;
    }
