ofbiz分页代码实现

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;
        }

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
