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;
    }
