public class ValuePropertyController extends ApplicationController{
    
	@Value("#{configProperties['']}")
	private String jdbcUrl; 
	
	@RequestMapping
	public String value(){
		(jdbcUrl);
		return "";
	}
}

<bean  class="">

           <list>
               <value>classpath:</value>
           </list>
