在我們的 spring boot 專案中，我們有 postgres 集成和 kakfa 消費者。對于 postgres 遷移，我們使用的是 flyway。
當我們嘗試啟動應用程式時，我們收到以下錯誤，我們在本地檢查了資訊，flyway 作業正常，只有在 prod 中它不起作用，任何想法都會有所幫助。
彈簧靴 - 2.4.10
彈簧卡夫卡 - 2.6.10
flyway-核心 - 7.1.1
PostgreSQL - 42.2.23
例外：
org.springframework.boot.context.properties.ConfigurationPropertiesBindException: Error creating bean with name 'spring.flyway-org.springframework.boot.autoconfigure.flyway.FlywayProperties': Could not bind properties to 'FlywayProperties' : prefix=spring.flyway, ignoreInvalidFields=false, ignoreUnknownFields=true; nested exception is java.lang.IllegalStateException: org.springframework.context.annotation.AnnotationConfigApplicationContext@5454d35e has not been refreshed yet

uj5u.com熱心網友回復：
如果您沒有定義 kafka 消費者應該何時在您的應用程式中啟動，默認情況下autoStartup值為 true，您的 Spring Boot 應用程式和 kafka 消費者容器將在其中并行啟動。
讓我們考慮一下這種情況，如果有任何 NW 延遲，那么資料庫連接和表創建程序將需要一些時間，您的 Spring Boot 應用程式將需要時間來初始化背景關系中的所有 bean。同時您的消費者容器已經開始消費來自 kafka 的訊息并期望DBobjects 繼續進行。
如果您的消費者資料流依賴于任何外部系統，最好先啟動您的 spring 應用程式，然后啟動 kafka 容器。
您必須使 autoStartup=false 和用戶 container.start() 或 endpointRegistry.start()，例如
ApplicationContext context = SpringApplication.run(App.class, args);
Map<String, KafkaListenerEndpointRegistry> registry = context.getBeansOfType(KafkaListenerEndpointRegistry.class);
registry.get("org.springframework.kafka.config.internalKafkaListenerEndpointRegistry").start();
