Package io.microsphere.annotation.processor

Class ConfigurationPropertyAnnotationProcessor

java.lang.Object

javax.annotation.processing.AbstractProcessor

io.microsphere.annotation.processor.ConfigurationPropertyAnnotationProcessor

All Implemented Interfaces:

javax.annotation.processing.Processor

@SupportedAnnotationTypes("io.microsphere.annotation.ConfigurationProperty")
public class ConfigurationPropertyAnnotationProcessor
extends javax.annotation.processing.AbstractProcessor

The Processor for the ConfigurationProperty annotation

This class processes the ConfigurationProperty annotations during the compilation phase, collects metadata about annotated elements, and generates a JSON metadata file that contains configuration property information.

• init(ProcessingEnvironment) initializes required utilities such as the Messager and ResourceProcessor.
• process(Set, RoundEnvironment) handles each processing round:
  • During normal rounds, it resolves metadata from annotated elements.
  • On the final round, it writes collected metadata into a resource file.
• resolveMetadata(RoundEnvironment) traverses all root elements to extract configuration property metadata.
• writeMetadata() writes the generated metadata into a JSON file under "META-INF/microsphere/configuration-properties.json" using a writer.
