Brief Description:

For Bean IDs, it is possible to create instances based on configuration dynamics when injected


Code:

Erepositoryconfigure.java

Package com.cpa.components.system.e.repository;
Import Org.apache.commons.lang3.Validate;
Import Org.springframework.beans.factory.annotation.Autowire;
Import Org.springframework.beans.factory.annotation.Value;
Import Org.springframework.context.annotation.Bean;

Import org.springframework.context.annotation.Configuration;
Import Com.cpa.components.system.e.repository.impl.edbrespository;

Import Com.cpa.components.system.e.repository.impl.eremoterepository; @Configuration public class Erepositoryconfigure {@Value ("${cpa.server.e.repository.group.type}") Private String type
	
	;
	
	Private Erepository repository; @Bean (Autowire = autowire.by_type, name = "Components.system.ERepository") public Erepository instance () {if (reposit
		Ory = null) {return repository;
			} switch (type) {case "Remote_system": Repository = new Eremoterepository ();
		Break
			Case "local_db": Repository = new Edbrespository ();
		Break
		Default:break; } validate.notnull (ReposiTory, "Invalid E repository type:[%s]", type);
	return repository; }
}
