14. Public class Mytaskxml {
20. public Void Show () {
22. System.out.println ("Xml:is show Run");
24. }
28. public void print () {
30. System.out.println ("xml:print run");

32. @Scheduled (cron = "0 0 1 * * *")
34. public Void Show () {
36. System.out.println ("Annotation:is show Run");
38. }
42. /**  
44. * Heartbeat update. Executes once at startup and then executes every 2 seconds
46. */
48. @Scheduled (fixedrate = 1000*2)
50. public void print () {
52. System.out.println ("annotation:print run");
54. }
56. }

4. Testing
