SpringBoot+Redis缓存简单配置_序列化

依赖：

    <!--redis-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

application.properties：

    #可以不用配置，有默认配置
    spring.redis.database=0
    spring.redis.host=127.0.0.1
    spring.redis.port=6379
    spring.redis.password=
    spring.redis.pool.max-active=8
    spring.redis.pool.max-wait=-1
    spring.redis.pool.max-idle=8
    spring.redis.pool.min-idle=1
    spring.redis.timeout=100

Redis配置类：

    @Configuration
    public class RedisConfig {
        /*缓存管理器配置*/
        @Bean
        public CacheManager cacheManager(@SuppressWarnings("rawtypes") RedisTemplate redisTemplate) {
            RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
            //设置缓存过期时间
            //FIXME 修改下边的缓存过期时间
            cacheManager.setDefaultExpiration(60*60);
            return cacheManager;
        }
        /*设置RedisTemplate*/
        @Bean
        public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory){
            StringRedisTemplate template = new StringRedisTemplate(factory);
            setSerializer(template);//设置序列化工具
            template.afterPropertiesSet();
            return template;
        }
        /*设置序列化工具*/
        private void setSerializer(StringRedisTemplate template){
            @SuppressWarnings({ "rawtypes", "unchecked" })
            Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
            ObjectMapper om = new ObjectMapper();
            om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
            jackson2JsonRedisSerializer.setObjectMapper(om);
            template.setValueSerializer(jackson2JsonRedisSerializer);
        }
    }
