springboot2.0x 和springboot 1.0 整合redis 使用自定义CacheManager的区别

springboot1.0x版本的 创建cachemanager 然后传入redistemple模板对象

  @Bean
    public RedisTemplate<Object, Employee> empRedisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
        RedisTemplate<Object, Employee> template = new RedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        Jackson2JsonRedisSerializer<Employee> serializer = new Jackson2JsonRedisSerializer<Employee>(Employee.class);
        template.setDefaultSerializer(serializer);
        return template;
    }

    @Bean
    public RedisCacheManager employeeCacheManager(RedisTemplate<Object,Employee> empRedisTemplate){
        RedisCacheManager cacheManager = new RedisCacheManager(empRedisTemplate);
        cacheManager.setTransactionAware(true);

        return cacheManager;
    }

而springboot2.0x版本的 可以直接这样使用rediscachemanager

 @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        RedisCacheConfiguration cacheConfiguration =
                RedisCacheConfiguration.defaultCacheConfig()
                        .entryTtl(Duration.ofDays(1))
                        .disableCachingNullValues()
                        .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new
                                GenericJackson2JsonRedisSerializer()));
        return RedisCacheManager.builder(factory).cacheDefaults(cacheConfiguration).build();
    }
