OFBIZ 分页代码

1. int viewSize = GlobalConstant.VIEW_SIZE;
2. int dataSize = 0;
3. int viewIndex = 0;
4. String temp = (String) map.get("viewIndex");
5. if (UtilValidate.isNotEmpty(temp)) {
6. try {
7. viewIndex = Integer.valueOf(temp);
8. } catch (NumberFormatException e) {
9. viewIndex = 0;
10. Debug.logError(e.getMessage().toString(), module);
11. }
12. }
13. int lowIndex = viewIndex * viewSize + 1;
14. int highIndex = (viewIndex + 1) * viewSize;
16. List<EntityCondition> condition = makeCondition(map);
17. EntityListIterator eli = null;
18. List<GenericValue> product = null;
19. try {
20. eli = delegator.find("test", EntityCondition.makeCondition(condition), null, null, UtilMisc
21. .toList(sortBy), null);
22. product = eli.getPartialList(lowIndex, viewSize);
23. eli.last();
24. dataSize = eli.currentIndex();
25. } catch (GenericEntityException e) {
26. Debug.logInfo(e.getMessage().toString(), module);
27. } finally {
28. try {
29. if (eli != null) {
30. eli.close();
31. eli = null;
32. }
34. } catch (GenericEntityException e) {
35. Debug.logError(e.getMessage().toString(), module);
36. }
37. }
38. if (highIndex > dataSize) {
39. highIndex = dataSize;
40. }

最主要的是：使用find方法，EntityListIterator现调用getPartialList方法
