根據“在整合springboot/shiro/redis 時，發現@Cacheable註解失效，如何解決？”處理springboot-shiro-redis自定義redis快取註解不進入aop問題？
(1) 在ShiroRealm中userService上加入@Lazy註解
(2) Redistemplate能存值但是取不到值
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
// 使用Jackson2JsonRedisSerialize 替換預設序列化
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
// 設定value的序列化規則和 key的序列化規則
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
