根据对应的contorller请求在方法的@Cacheable注解上添加cacheManager = "cacheManager1Hour",可根据公司的业务需求配置不同的过期时间类型，序列化是一样的，拿来直接用即可。@Primary注解表示默认值，如果你没有配就会采用这个注解下的过期时间。

@Bean 
@Primary 
public RedisCacheManager cacheManager1Hour(RedisConnectionFactory connectionFactory) { RedisCacheConfiguration config = instanceConfig(3600L); 
return RedisCacheManager.builder(connectionFactory) 
                        .cacheDefaults(config) 
                        .transactionAware() 
                        .build(); 
                                                                                       }

 private RedisCacheConfiguration instanceConfig(Long ttl) {

Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class); 
ObjectMapper objectMapper = new ObjectMapper(); objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS); objectMapper.registerModule(new JavaTimeModule()); 
// 去掉各种@JsonSerialize注解的解析 objectMapper.configure(MapperFeature.USE_ANNOTATIONS, false); 
// 只针对非空的值进行序列化 objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL); 
// 将类型序列化到属性json字符串中 objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance , ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);
jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
return RedisCacheConfiguration.defaultCacheConfig() 
                              .entryTtl(Duration.ofSeconds(ttl))                               .disableCachingNullValues()
                                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer));
}
