Spring Cache 注解@Cachable 、@CachePut、@CacheEvict 实现自定义过期时间

在使用Spring Cache 的时候，在RedisConfig中已经对其的默认过期时间定死了，但是，对于一些其他的缓存需要自己的过期时间，需要在进行其他配置。

根据自己的需求进行配置

 Map<String, RedisCacheConfiguration> cacheConfigurations = new HashMap<>();
cacheConfigurations.put("cache:blog:hot", RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofHours(1)));

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        RedisSerializer<String> redisSerializer = new StringRedisSerializer();
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        //解决查询缓存转换异常的问题
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        // 配置序列化（解决乱码的问题）,过期时间600秒
        Map<String, RedisCacheConfiguration> cacheConfigurations = new HashMap<>();

        cacheConfigurations.put("cache:blog:hot", RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofHours(1)));
//        cacheConfigurations.put("cacheName2", RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofMinutes(30)));


        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofSeconds(600)) //缓存过期10分钟 ---- 业务需求。
                .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer))//设置key的序列化方式
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer)) //设置value的序列化
                .disableCachingNullValues();
        RedisCacheManager cacheManager = RedisCacheManager.builder(factory)
                .withInitialCacheConfigurations(cacheConfigurations)
                .cacheDefaults(config)
                .build();
        return cacheManager;
    }
