我无法在KotlinSping Boot 应用程序中正确注入@Value
应用程序属性。在我的application.yml
文件中定义的属性,随后在additional-spring-configuration-metadata.json
文件中引用(在resources -> META-INF下),没有正确地添加到bean表达式上下文。使用IntelliJ version 2020.2.1
,当鼠标悬停在属性上时,我看到一个Cannot resolve configuration property
错误。尝试运行应用程序(将配置属性值构造注入到类中)会导致Unsatisfied dependency expressed through constructor parameter
错误。

我已经添加了注解处理依赖项,使缓存无效并重新启动,并使用了Kotlin特定的注解处理器(kapt)。我也遵循了这里的指示:https://www.jetbrains.com/help/idea/annotation-processors-support.html
我错过了什么?任何和所有的帮助将不胜感激。谢谢!

如果您的
application.yml
(或application.properties
)看起来像这样:然后尝试将每个属性重写为每个属性的全名格式:
wfveoks02#
您需要将以下内容声明为
annotationProcessor
