安全与性能优化

分布式锁与并发控制

系统采用Redis分布式锁确保高并发场景下的数据一致性。

分布式锁服务：

@Service
public class DistributedLockService {
    
    @Autowired
    private RedisTemplate<String, Object> redisTemplate;
    
    public <T> T executeWithLock(String lockKey, Duration timeout, Supplier<T> supplier) {
        String lockValue = UUID.randomUUID().toString();
        Boolean lockAcquired = false;
        
        try {
            lockAcquired = redisTemplate.opsForValue()
                .setIfAbsent(lockKey, lockValue, timeout);
            
            if (Boolean.TRUE.equals(lockAcquired)) {
                return supplier.get();
            } else {
                throw new ConcurrentAccessException("系统繁忙，请稍后重试");
            }
        } finally {
            if (Boolean.TRUE.equals(lockAcquired)) {
                // 只有当前线程持有的锁才释放
                String currentValue = (String) redisTemplate.opsForValue().get(lockKey);
                if (lockValue.equals(currentValue)) {
                    redisTemplate.delete(lockKey);
                }
            }
        }
    }
}

缓存架构与性能优化

通过多级缓存策略和数据库优化确保系统高性能。

缓存配置示例：

@Configuration
@EnableCaching
public class CacheConfig {
    
    @Bean
    public RedisCacheManager cacheManager(RedisConnectionFactory factory) {
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
            .entryTtl(Duration.ofMinutes(30))
            .disableCachingNullValues()
            .serializeValuesWith(RedisSerializationContext.SerializationPair
                .fromSerializer(new GenericJackson2JsonRedisSerializer()));
        
        return RedisCacheManager.builder(factory)
            .cacheDefaults(config)
            .withCacheConfiguration("taskList", 
                RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofMinutes(5)))
            .withCacheConfiguration("userProfile",
                RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofHours(1)))
            .withCacheConfiguration("taskRecommendations",
                RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofMinutes(10)))
            .build();
    }
}

全球化支持与本地化策略

系统支持多语言、多货币、多时区，满足国际化业务需求。

国际化服务：

@Service
public class InternationalizationService {
    
    @Autowired
    private MessageSource messageSource;
    
    public String getMessage(String code, String language, Object... args) {
        Locale locale = Locale.forLanguageTag(language);
        return messageSource.getMessage(code, args, locale);
    }
    
    // 货币转换
    public BigDecimal convertCurrency(BigDecimal amount, String fromCurrency, String toCurrency) {
        if (fromCurrency.equals(toCurrency)) {
            return amount;
        }
        
        ExchangeRate rate = exchangeRateRepository
            .findLatestRate(fromCurrency, toCurrency)
            .orElseThrow(() -> new ExchangeRateNotFoundException("汇率不存在"));
        
        return amount.multiply(rate.getRate());
    }
    
    // 时区处理
    public LocalDateTime convertTimeZone(LocalDateTime time, String fromZone, String toZone) {
        ZonedDateTime fromZoned = time.atZone(ZoneId.of(fromZone));
        ZonedDateTime toZoned = fromZoned.withZoneSameInstant(ZoneId.of(toZone));
        return toZoned.toLocalDateTime();
    }
}
