All Implemented Interfaces:
PropertySource
public class SystemPropertiesSource extends JavaPropertiesSource
A PropertySource implementation that reads configuration properties from the JVM system properties.

This source delegates to System.getProperties() to retrieve key-value pairs. It allows for application configuration using the -Dkey=value syntax when starting the JVM.

Example:

java -Dmy.config.value=42 -jar my-app.jar

This value could then be resolved via PropertySource#get("my.config.value").
