Component uses Properties directly, performing type conversion and error checking as appropriate.
org.springframework.core.env.Environment is not a good approach, but it could be useful when the name of the property you need to access changes dynamically.

@Component

public void method(String pathPropertyName) {

String path = env.getProperty(pathPropertyName);

@NotNull
@ParameterGroupConstraint

ClRuntimeParameterGroup defined before could be injected into components.

long heartBeatMs = parameters.getHeartBeatMs();
