无法将属性绑定到“FlywayProperties”，AnnotationConfigApplicationContext@5454d35e 尚未刷新

Question

在我们的 Spring Boot 项目中，我们有 postgres 集成和 kakfa 消费者。对于 postgres 迁移，我们使用的是 flyway。

当我们尝试启动应用程序时，我们收到以下错误，我们在本地检查了信息，flyway 工作正常，只是在 prod 它不工作，任何想法都会有所帮助。

spring-boot - 2.4.10

spring-kafka - 2.6.10

flyway-core - 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

如果您没有定义何时应在您的应用中启动 kafka 消费者，则 autoStartup 值默认为 true，您的 Spring boot 应用程序和 kafka 消费者容器将并行启动。

让我们考虑一下这种情况，如果有任何 NW 延迟，那么 DB 连接和表创建过程将需要一些时间，您的 Spring Boot 应用程序将需要时间来初始化上下文中的所有 bean。同时您的消费者容器已经开始使用来自的消息kafka 并期望 DBobjects 继续进行。

如果您的消费者数据流依赖于任何外部系统，最好先启动您的 spring 应用程序，然后启动 kafka 容器。

您必须使 autoStartup=false 和用户 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();
