未绑定==>concur KV Kotlin Spring Boot@ConfigurationProperties@ConstructorBinding

Question

我需要把我们的application.yml配置转移到哈希公司的领事那里。我已经创建了一个简单的Spring Boot应用程序来完成所需的更改。它将配置数据从application.yml加载到强类型类。

但是，在对应用程序进行注释之后。yml文件和引导中的启用领事。yml文件，当我尝试访问Concur KV中的相同配置时，配置数据总是空的，Concur KV在我的系统上作为Docker映像运行。我一定错过了一些简单的东西，但我完全不知道它是什么。以下是相关信息。

Answer 1

因此，我通过创建一个java项目并使其工作，解决了这个问题。接下来，基于我的Java项目，我创建了一个反应式的Kotlin版本。这两个项目都能正常工作，并且是独立的。我希望他们能帮助别人。以下是项目的链接：

Answer 2

AppProperties类不是Spring管理的bean。您需要添加@EnableConfigurationProperties（AppProperties::class）到Spring管理bean：

@SpringBootApplication(scanBasePackages = ["com.example.myconsul"])
@EnableConfigurationProperties(AppProperties::class)
class MyConsulApplication

之后，您的属性类将由Spring上下文管理。

如果您希望它是可变的，并且可以通过@Reresscope刷新，那么您需要删除@ConstructorBinding并重写您的AppProperties，如下所示：

@ConstructorBinding
@RefreshScope
@ConfigurationProperties("myconsul")
class AppProperties {
    lateinit var message: String

    @PostConstruct
    fun postConstruct() {
        println("====> $message")
    }
}
