кеш пружины (рейды) maxWait недействителен

0 голосов
/ 09 апреля 2019

Я использую Redis в своем приложении Springboot.Когда сервер Redis завершает работу, он блокирует много времени и генерирует исключение PoolException.Что я могу сделать, чтобы сократить время блока?Спасибо!

То, что я пробовал, было установлено для свойства timeout и maxWait до 100 мс, но не работало.

Служба: 

@Service
public class TestService {

    @Cacheable(cacheNames = "test:hello")
    public String test(String name) {
        System.out.println("invoke...");
        return "hello " + name;
    }

}

Контроллер: 

@RestController
public class TestController {

    @Autowired
    private TestService testService;

    @GetMapping("/test")
    public Object test(@RequestParam String name) {
        return testService.test(name);
    }

}

Конфиг: 

@Configuration
public class RedisConfiguration extends CachingConfigurerSupport {

    public static final Logger LOG = LoggerFactory.getLogger(RedisConfiguration.class);

    @Bean
    public RedisCacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisCacheManager redisCacheManager = RedisCacheManager.RedisCacheManagerBuilder
                .fromConnectionFactory(redisConnectionFactory).build();
        return redisCacheManager;
    }

    @Override
    public CacheErrorHandler errorHandler() {
        return new CacheErrorHandler() {
            @Override
            public void handleCacheGetError(RuntimeException exception, Cache cache, Object key) {
                if (exception instanceof PoolException) {
                    LOG.error(exception.getMessage());
                } else {
                    throw exception;
                }
            }

            @Override
            public void handleCachePutError(RuntimeException exception, Cache cache, Object key, Object value) {
                if (exception instanceof PoolException) {
                    LOG.error(exception.getMessage());
                } else {
                    throw exception;
                }
            }

            @Override
            public void handleCacheEvictError(RuntimeException exception, Cache cache, Object key) {
                if (exception instanceof PoolException) {
                    LOG.error(exception.getMessage());
                } else {
                    throw exception;
                }
            }

            @Override
            public void handleCacheClearError(RuntimeException exception, Cache cache) {
                if (exception instanceof PoolException) {
                    LOG.error(exception.getMessage());
                } else {
                    throw exception;
                }
            }
        };
    }
}
