Spring Boot Redis 组件配置

@Configuration
public class RedisConfig {
   //基于注解的序列化设置
   @Bean
   public RedisCacheManager redisCacheManager(RedisConnectionFactory redisConnectionFactory, CacheProperties cacheProperties) {
      //序列化方式，分别为String格式和Json格式

      ObjectMapper om = new ObjectMapper();
      //解决查询缓存转换异常问题
      om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
      om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
      //设置转换核心类
      jackson2JsonRedisSerializer.setObjectMapper(om);
      //用于读取配置文件，内部使用@ConfigurationProperties(prefix = "spring.cache")注解
      CacheProperties.Redis redisProperties = cacheProperties.getRedis();
