使用spring-data-redis2.x版本时，将@Cacheable缓存key值时默认会给value或cacheNames后加上双冒号 改为 单冒号

默认双冒号：

修改配置：

@Configuration
@EnableCaching
public class RedisCacheConfig extends CachingConfigurerSupport {
    /**
     * 缓存配置管理器
     */
    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        // 以锁写入的方式创建RedisCacheWriter对象
        RedisCacheWriter writer = RedisCacheWriter.lockingRedisCacheWriter(factory);
        // 设置CacheManager的Value序列化方式
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = jackson2JsonRedis();
        RedisSerializationContext.SerializationPair pair = RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer);
        // 创建默认缓存配置对象、 将@Cacheable缓存key值时默认会给value或cacheNames后加上双冒号 改为 单冒号
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig().serializeValuesWith(pair).computePrefixWith(name -> name + ":");
        RedisCacheManager cacheManager = new RedisCacheManager(writer, config);
        return cacheManager;
    }
    
    // 其他配置...
}

或者：

@Configuration
public class SpringCacheConfig{
    @Bean
    public CacheManager cacheManager(LettuceConnectionFactory lettuceConnectionFactory){        
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()        
                .entryTtl(Duration.ofHour(1)                
                //变双冒号为单冒号
                .computePrefixWith(name -> name +":")                
                .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()))                
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()))    
                .disableCachingNullValues();                
        RedisCacheManager cacheManager = RedisCacheManager.RedisCacheManagerBuilder        
                .fromConnectionFactory(lettuceConnectionFactory)                
                .cacheDefaults(config)                
                .transactionAware()                
                .build();
        return cacheManager;    
    }
    ...其他配置
}
