##### 先看Springboot1.5的配置方法 #####

@Configuration
    public class MyRedisConfig { 
    
        @Bean
        public RedisTemplate<Object, Object> RedisTemplate(
                RedisConnectionFactory redisConnectionFactory)
                throws UnknownHostException { 
            RedisTemplate<Object, Object> template = new RedisTemplate<Object, Object>();
            template.setConnectionFactory(redisConnectionFactory);
            //采用Jackson2JsonRedisSerializer序列化机制
            Jackson2JsonRedisSerializer<Object> ser = new Jackson2JsonRedisSerializer<Object>(Employee.class);
            template.setDefaultSerializer(ser);
            
            return template;
        }
    	 @Primary  //将某个缓存管理器作为默认的
        @Bean
        public RedisCacheManager CacheManager(RedisTemplate<Object, Object> empRedisTemplate){ 
        	//通过注入RedisTemplate得到cacheManager
            RedisCacheManager cacheManager = new RedisCacheManager(RedisTemplate);
            cacheManager.setUsePrefix(true);
    
            return cacheManager;
        }
    }

##### Springboot2.0版本以上的配置方式 #####

@Configuration
    public class MyRedisConfig { 
    
        @Bean
        public RedisCacheManager cacheManager(RedisConnectionFactory connectionFactory) { 
            //初始化一个RedisCacheWriter输出流
            RedisCacheWriter redisCacheWriter = RedisCacheWriter.nonLockingRedisCacheWriter(connectionFactory);
    		//采用Jackson2JsonRedisSerializer序列化机制
            Jackson2JsonRedisSerializer<Object> serializer = new Jackson2JsonRedisSerializer<Object>(Employee.class);
    		//创建一个RedisSerializationContext.SerializationPair给定的适配器pair
            RedisSerializationContext.SerializationPair<Object> pair = RedisSerializationContext.SerializationPair.fromSerializer(serializer);
    		//创建CacheConfig
            RedisCacheConfiguration defaultCacheConfig = RedisCacheConfiguration.defaultCacheConfig().serializeValuesWith(pair);
    		
            return new RedisCacheManager(redisCacheWriter, defaultCacheConfig);
        }
    }
