Java代码
- int viewSize = GlobalConstant.VIEW_SIZE;
- int dataSize = 0;
- int viewIndex = 0;
- String temp = (String) map.get("viewIndex");
- if (UtilValidate.isNotEmpty(temp)) {
- try {
- viewIndex = Integer.valueOf(temp);
- } catch (NumberFormatException e) {
- viewIndex = 0;
- Debug.logError(e.getMessage().toString(), module);
- }
- }
- int lowIndex = viewIndex * viewSize + 1;
- int highIndex = (viewIndex + 1) * viewSize;
- List condition = makeCondition(map);
- EntityListIterator eli = null;
- List product = null;
- try {
- eli = delegator.find("test", EntityCondition.makeCondition(condition), null, null, UtilMisc
- .toList(sortBy), null);
- product = eli.getPartialList(lowIndex, viewSize);
- eli.last();
- dataSize = eli.currentIndex();
- } catch (GenericEntityException e) {
- Debug.logInfo(e.getMessage().toString(), module);
- } finally {
- try {
- if (eli != null) {
- eli.close();
- eli = null;
- }
- } catch (GenericEntityException e) {
- Debug.logError(e.getMessage().toString(), module);
- }
- }
- if (highIndex > dataSize) {
- highIndex = dataSize;
- }
最主要的是：使用find方法，EntityListIterator现调用getPartialList方法
