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;
