调用计划任务时出错 实例化 [io.micronaut.configuration.lettuce.health.RedisHealthIndicator] 类型的 bean 时出错
Error invoking scheduled task Error instantiating bean of type [io.micronaut.configuration.lettuce.health.RedisHealthIndicator]
我在运行这个时间表时遇到以下问题。
@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();
}
}
}
第一次执行没问题，超时再执行就报如下错误

当自动配置所述数据源时，可能会发生此类错误。如果您不在应用程序中使用 Redis 自动配置，则可以禁用它。如果您的应用程序需要 Redis，那么您应该设置 spring.redis.host 和 spring.redis.port.
你能检查一下你是否有 io.micronaut.redis:micronaut-redis-lettuce 依赖添加到你的 class 路径/构建文件中吗？
默认情况下，Micronaut 将假定 redis 服务器位于 localhost:6379，因为当 redis-lettuce 被激活时，健康检查默认启用。它将继续探测健康检查。
如果您使用的是 micronaut application.yml，您需要提供服务器 url，可以从 运行 应用访问该服务器。
示例 - application.yml
redis:
uri: redis://localhost
ssl: true
timeout: 30s
您还可以使用以下连接字符串模式来提供有关 redis 服务器的详细信息。
Redis 独立版
redis :// [[username :] password@] host [: port] [/ database][?
[timeout=timeout[d|h|m|s|ms|us|ns]] [&_database=database_]]
Redis 独立版 (SSL)
