@Configuration
@EnableCaching
public class CacheConfig {
    
    @Bean
    public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisCacheConfiguration cacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer.json()));
        
        return RedisCacheManager.builder(redisConnectionFactory)
                .cacheDefaults(cacheConfiguration)
                .build();
    }
}

@Service
public class ExampleService {
    
    @Cacheable(value = "exampleCache", key = "#id")
    public ExampleEntity getExampleEntityById(Long id) {
        // 从数据库或其他数据源获取数据
        return exampleEntity;
    }
}
