Spring Cloud Stream 应用程序自定义属性未显示在 Cloud Data Flow 中 UI

Question

创建了具有自定义属性的处理器应用程序。应用程序属性已列入白名单。在将应用程序注册到 Spring 云数据流时，自定义属性未显示在应用程序属性 UI 页面中。

@EnableBinding(Processor.class)
@EnableConfigurationProperties(CustomProperties.class)

public class CustomProcessorApplication {

    @Autowired
    private CustomProperties processorProperties;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties
public class CustomProperties {

Entry in src/main/resources/META-INF/dataflow-configuration-metadata-whitelist.properties

Answer 1

您需要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，dataflow-configuration-metadata-whitelist.properties 已弃用，取而代之的是 dataflow-configuration-metadata.properties。
