配置好自定义RedisCacheManager 组件，就可以自动将要保存的数据以JSON格式存入Redis
1 @Configuration 2 public class MyRedisConfig { 3 4 @Bean 5 public RedisCacheManager cacheManager(RedisConnectionFactory factory) { 6 7 RedisSerializer<String> redisSerializer = new StringRedisSerializer(); 8 Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class); 9 10 //解决查询缓存转换异常的问题 11 ObjectMapper om = new ObjectMapper(); 12 om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY); 13 om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL); 14 jackson2JsonRedisSerializer.setObjectMapper(om); 15 16 //配置序列化(解决乱码的问题) 17 RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig() 18 .entryTtl(Duration.ZERO) 19 .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer)) 20 .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer)) 21 .disableCachingNullValues(); 22 23 RedisCacheManager cacheManager = RedisCacheManager.builder(factory) 24 .cacheDefaults(config) 25 .build(); 26 return cacheManager; 27 } 28 }
