查看Redis的数据，发现无缘无故多了内容(\\x00\\x00)

经过一系列调试，问题出在这，没有设置时间单位

如果不设置时间单位，那么第三个会是偏移量

#### 解决方案 ####

加上时间单位

如果这个不能解决的话，可以改下RedisConfig配置是否正确

import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.connection.RedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.*;
    
    /**
     * Redis配置类
     */
    @Configuration
    @EnableCaching
    public class RedisConfig {
        
        // 声明模板
        /*
        ref = 表示引用
        value = 具体的值
        <bean class="org.springframework.data.redis.core.RedisTemplate" >
            <property name="defaultSerializer" ref = "">
        </bean>
         */
        @Bean
        public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        
            RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
            redisTemplate.setConnectionFactory(redisConnectionFactory);
            GenericJackson2JsonRedisSerializer jackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
            // 设置值（value）的序列化采用FastJsonRedisSerializer。
            redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
            // 设置键（key）的序列化采用StringRedisSerializer。
            redisTemplate.setKeySerializer(new StringRedisSerializer());
            redisTemplate.setHashKeySerializer(new StringRedisSerializer());
            redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
            redisTemplate.afterPropertiesSet();
            return redisTemplate;
        }
    
    }
