springboot2的redis缓存管理器cacheManager配置，使存入json格式数据

springboot中默认存入缓存的数据，使用的序列化方案对应的值不方便查看，我们希望存入json格式值，所以要配置cacheManager达到效果

springboot2的缓存管理器配置和springboot1有所差别，所以记录下来：

效果图：

1cacheManager配置代码：
2
3//缓存管理器
4    @Bean(name = "cacheManager")
5    @Primary
6    public CacheManager cacheManager(ObjectMapper objectMapper, RedisConnectionFactory redisConnectionFactory) {
7        //设置序列化
8        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
9        ObjectMapper om = new ObjectMapper();
10        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
11        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
12        jackson2JsonRedisSerializer.setObjectMapper(om);
13
14        RedisCacheConfiguration cacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
15                .disableCachingNullValues()
16//                .computePrefixWith(cacheName -> "yourAppName".concat(":").concat(cacheName).concat(":"))
17                .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()))
18                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer));
19
20        return RedisCacheManager.builder(redisConnectionFactory)
21                .cacheDefaults(cacheConfiguration)
22                .build();
23    }
