  4.   
  5. public class Test {  
  6. public static void main(String[] args) {  
  7. ExpressionParser parser = new SpelExpressionParser();  
  8.   
  9. //arithmetic operator  
  10. System.out.println(parser.parseExpression("'Welcome SPEL'+'!'").getValue());  
  11. System.out.println(parser.parseExpression("10 * 10/2").getValue());  
  12. System.out.println(parser.parseExpression("'Today is: '+ new java.util.Date()").getValue());  
  13.
