运行此计划时出现以下问题。

@Singleton
public class TaskScheduler {

    private static final Logger LOG = LoggerFactory.getLogger(TaskScheduler.class);

    @Inject
    private BuildLayerJob buildLayerJob;

    @Scheduled(fixedDelay = "30s", initialDelay = "30s")
    public void loadRegistriesDescriptions(){
        try {
            LOG.info("Cargando lista de registries cada 30s.");
            buildLayerJob.getBuildLayer().loadRegistries();
        }
        catch(Exception exception) {
            LOG.error("Error cargando lista de registries cada 30s: " +exception.getMessage());
            //exception.printStackTrace();
        }
    }
}

在第一次执行中没有问题，但是当时间到期并且再次执行时，它抛出以下错误。

我知道redis的连接有问题，但是在gcp中部署的微服务中，它继续产生同样的问题。
附录yaml

runtime:    java11
service:    default
instance_class: B2

env_variables:
  LAYERS_SERVER_PORT: 8080
  REDIS_FIXEDDELAY: 1s
  REDISA_URL: "redis://A"
  REDISB_URL: "redis://B"
  REDISC_URL: "redis://C"
  REDISD_URL: "redis://D"

basic_scaling:
  max_instances: 1
  idle_timeout: 270s
vpc_access_connector:
  name: "projects/example/locations/us-central1/connectors/example"

本地设置。应用程序.yml：

micronaut:
  application:
    name: example
  server:
    port: ${EXAMPLE_SERVER_PORT:3000}
    cors:
      enabled: true
---
redis:
  servers:
    REDISA:
      uri: redis://IP_A
    REDISB:
      uri: redis://IP_B
    REDISC:
      uri: redis://IP_C
    REDISD:
      uri: redis://IP_D

存储库层.server.repo.inforepositoryimpl:

@Singleton
public class InfoRepositoryImpl implements InfoRepository {

    private BuildLayerJob buildLayerJob;

    @Inject @Named("REDISB")  RedisAsyncCommands<String, String> reddisConnectionB;
    @Inject @Named("REDISA")  RedisAsyncCommands<String, String> reddisConnectionA;

private static final Logger LOG = LoggerFactory.getLogger(InfoRepositoryImpl.class);

    public InfoRepositoryImpl(BuildLayerJob buildLayerJob) {
        this.buildLayerJob = buildLayerJob;
    }

当所述数据源被自动配置时，这种错误可能发生。如果应用程序中没有使用redis自动配置，则可以禁用它。如果应用程序需要redis，那么应该设置 spring.redis.host 以及 spring.redis.port .

你能检查一下你有没有 io.micronaut.redis:micronaut-redis-lettuce 已将依赖项添加到类路径/生成文件中。
默认情况下，micronaut将假定redis服务器处于localhost:6379，因为在激活redis时默认启用运行状况检查。它将继续探测健康检查。
如果您使用的是micronaut application.yml，则需要提供可从运行的应用程序访问的服务器url。
micronaut redis公司
示例-application.yml

redis:
    uri: redis://localhost
    ssl: true
    timeout: 30s

您还可以使用下面的连接字符串模式来提供有关redis服务器的详细信息。
redis单机版
redis://[[用户名：]密码@]主机：端口][/数据库][[timeout=timeout[d | h | m | s | ms | us | ns]][&u database=database |]]
redis单机版（ssl）
redis://[[用户名：]密码@]主机：端口][/数据库][[timeout=timeout[d | h | m | s | ms | us | ns]][&u database=database |]]
redis独立（unix域套接字）
redis socket://[[username:]password@]路径[？[timeout=timeout[d | h | m | s | ms | us | ns]][&| u database=database |]]
