环境:SpringBoot2.X + SpringCache + Redis
- Spring boot默认使用的是SimpleCacheConfiguration,使用ConcurrentMapCacheManager来实现缓存。
配置:
spring: redis: host: 192.168.1.192 database: 1 port: 6379 password: 123456 timeout: 1s jedis: pool: max-active: 20 max-idle: 20 min-idle: 10 max-wait: -1ms cache: redis: use-key-prefix: true key-prefix: dev cache-null-values: false time-to-live: 20s
解决redis保存数据乱码的问题
- 解决从redis反序列化报错的问题
- 增加失效时间
@Configuration @ConfigurationProperties(prefix = "spring.cache.redis") public class SpringCacheRedisConfig { private Duration timeToLive = Duration.ZERO; public void setTimeToLive(Duration timeToLive) { this.timeToLive = timeToLive; } @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) RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig() .entryTtl(timeToLive) .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer)) .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer)) .disableCachingNullValues(); RedisCacheManager cacheManager = RedisCacheManager.builder(factory) .cacheDefaults(config) .build(); return cacheManager; } }
