jq.Grid 分页后台代码

ArrayList list= ktrService.findKtr(NAME);//从service获得结果集

int totalRecord = list.size(); // 总记录数
int totalPage = totalRecord % Integer.parseInt(rows) == 0 ? totalRecord
/ Integer.parseInt(rows) : totalRecord / Integer.parseInt(rows)
+ 1; // 计算总页数

try {
int index = (Integer.parseInt(page) - 1) * Integer.parseInt(rows); // 开始记录数

int pageSize = Integer.parseInt(rows);
// 以下模拟构造JSON数据对象
String json = "{\"total\": \"" + totalPage + "\", \"page\": \"" + page
+ "\", \"records\": \"" + totalRecord + "\", \"rows\": [";
for (int i = index; i < pageSize + index && i < totalRecord; i++) {
