Answer 1

你需要有spring-boot-configuration-processor，例如，

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-configuration-processor</artifactId>
</dependency>

此外，如果您使用的是 SCDF 2.6 或更高版本，则不推荐使用 dataflow-configuration-metadata-whitelist.properties 以支持 dataflow-configuration-metadata.properties。
