spring缓存配置

配置redis缓存 并设置值序列化为json格式

	//springboot会自动注入该bean
    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
   
        RedisStandaloneConfiguration redisStandaloneConfiguration =
                new RedisStandaloneConfiguration();
        redisStandaloneConfiguration.setHostName(host);
        redisStandaloneConfiguration.setPort(port);
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisStandaloneConfiguration);
        return jedisConnectionFactory;
    }
    
     @Bean
    public RedisCacheManager cacheManager(RedisConnectionFactory connectionFactory) {
   
        //默认1
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig();
        config = config.serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(keySerializer()));
        config = config.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(valueSerializer()));
        config = config.disableCachingNullValues();
        RedisCacheManager redisCacheManager = RedisCacheManager.builder(connectionFactory)
                .cacheDefaults(config)
                .transactionAware()
                .build();
        log.debug("自定义RedisCacheManager加载完成");

        return redisCacheManager;
    }

    //键得序列号
    private RedisSerializer<String> keySerializer() {
   
        return new StringRedisSerializer();
    }

    //值得序列号
    private RedisSerializer<Object> valueSerializer() {
   
        return new GenericJackson2JsonRedisSerializer();
    } 

spring使用本地缓存配置 注：sprinboot导入缓存场景启动器自动为本地缓存 不需要该配置

    /** * 使用本地缓存 */
    @Bean
    public CacheManager cacheManager(List<Cache> caches) {
   
        SimpleCacheManager simpleCacheManager = new SimpleCacheManager();
        simpleCacheManager.setCaches(caches);
        return simpleCacheManager;
    }

    @Bean
    public ConcurrentMapCacheFactoryBean dictCkind() {
   
        ConcurrentMapCacheFactoryBean stockDetail = new ConcurrentMapCacheFactoryBean();
        // 如果用户设置名称为stockDetail的缓存，则需要添加这样的一个bean
        //stockDet
        return stockDetail;
    }

spring中配置maven
