Spring redis缓存明码

Question

我使用redis为我的Spring应用程序实现了缓存。现在，我想运行一个作业，每天将Mysql中的数据同步到redis。但我有个问题，redis key不是人类可读的文本。例如userList2:��在使用spring Cache时，如何将redis key存储为纯文本？

您可以在cacheManager配置中使用自定义redis模板将值存储为json。

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
    redisTemplate.setConnectionFactory(redisConnectionFactory);
    redisTemplate.setKeySerializer(new StringRedisSerializer());
    redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
    redisTemplate.setHashKeySerializer(new StringRedisSerializer());
    redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
    return redisTemplate;
}

@Bean
public CacheManager cacheManager(RedisTemplate redisTemplate) {
    RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
    cacheManager.setUsePrefix(true);
    return cacheManager;
}
