public class SpringTypeConverterExample {
	public static void main(String[] args) throws IOException {
		
		GenericConversionService springconversionService = ConversionServiceFactory.createDefaultConversionService();
		//Integer to String
		
		String str = springconversionService.convert(222,String.class);
		System.out.println(str);
		
		//String to Integer
		
		Integer integer = springconversionService.convert("100",Integer.class);
		System.out.println(integer);
		
		//Comma separated String to List
