在把RedisTemplate注入Spring容器的时候,如果不设置RedisTemplate的序列化,在Redis存数据的时候,key前边追加了一些编码数据,加上这个设置会把这些编码数据给去掉

@SpringBootApplication
@EnableDiscoveryClient
@MapperScan(basePackages = {"com.changgou.seckill.dao"})
@EnableScheduling
public class SecKillApplication {
    public static void main(String[] args) {
        SpringApplication.run(SecKillApplication.class,args);
    }

    @Bean
    public IdWorker idWorker(){
        return new IdWorker(1,1);
    }

     /**
             * 设置 redisTemplate 的序列化设置
             * @param redisConnectionFactory
             * @return
             */
            @Bean
            public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
                // 1.创建 redisTemplate 模版
                RedisTemplate<Object, Object> template = new RedisTemplate<>();
                // 2.关联 redisConnectionFactory
                template.setConnectionFactory(redisConnectionFactory);
                // 3.创建 序列化类
                GenericToStringSerializer genericToStringSerializer = new GenericToStringSerializer(Object.class);
                // 6.序列化类，对象映射设置
                // 7.设置 value 的转化格式和 key 的转化格式
                template.setValueSerializer(genericToStringSerializer);
                template.setKeySerializer(new StringRedisSerializer());
                template.afterPropertiesSet();
                return template;
            }
